Article Citation - WoS: 24Citation - Scopus: 27Determination of Moment, Shear and Ductility Capacities of Spiral Columns Using an Artificial Neural Network(ELSEVIER, 2019-11-01) Koçer, Mustafa; Öztürk, Murat; Arslan, M. HakanIntelligent systems are frequently used to solve difficult and complex problems in today's world. Especially in the discipline of civil engineering, much research has been conducted with the help of intelligent systems. The objective of this study is to identify the moment and shear force capacities of reinforced concrete spiral columns and their displacement ductility values by using an algorithm based on an Artificial Neural Network (ANN). In the study, 86 different spiral column experiments tested in the literature were compiled, and the moment and shear force capacities obtained through the experiments were arranged at a certain level. In addition, the ductility values of the tested columns were calculated using graphical experimental data. The output layer consists of four neural network models, which are ANN(1) (with three output neurons), ANN(2), ANN(3), and ANN(4) (with one output neuron), and moment, shear force capacity, and displacement ductility parameters were obtained, respectively. According to results of this study, it was observed that moment and shear force capacities of spiral columns could be particularly well estimated using ANN. However, it was found that the estimation success of ANN for displacement ductility was not sufficient.Article Citation - WoS: 7Citation - Scopus: 9Experimental and Numerical Investigation of the Structural, Thermal and Acoustic Performance of Reinforced Concrete Slabs With Balls for a Cleaner Environment(Springer Int Publ Ag, 2023-01-18) Arslan, Musa Hakan; Özkilic, Yasin Onuralp; Arslan, H. Derya; Sahin, Ömer SinanThis study conducted a comprehensive experimental and numerical assessment to investigate the effect of plastic circular balls placed in the middle of a section of a reinforced concrete slab on strength, ductility, thermal, and acoustic performance. The ball diameter/slab thickness (D/H), grades of concrete, and longitudinal tensile reinforcement ratio (rho) in the slab were selected as the main variables. The variation in thermal and acoustic performance depending upon the ball's diameter was investigated as well. The results showed that the slab's load-carrying capacity, ductility, and energy dissipation capacity did not differ if the D/H ratio did not exceed 0.4; however, significant decreases in these values were observed when the D/H ratio exceeded 0.4. Moreover, the increase in the concrete and reinforcement's strength had a negative effect on the slab with a D/H ratio of 0.8. The experimental results revealed that balled slabs are 3.15 times superior with respect to thermal conductivity and provide 1.38 times more insulation to absorb sound compared to non-balled slabs. In the numerical study of the slabs' thermal performance, the mean surface temperature and heat flux on the slab where the heat transfer takes place decreased as the ball diameter increased. As seen in acoustic models, the level at which the slabs absorbed sound varied depending upon both the diameter of the balls and the sound frequency.Article Citation - WoS: 8Citation - Scopus: 8An Experimental Investigation and Cost Analysis of Flexural or Shear Strengthening Pre-Damaged Rc Beams(Elsevier Ltd, 2024-04-01) Aslan, S.; Erkan, İ.H.; Aksoylu, C.; Arslan, M.H.; Erkan, brahim HakkiThis study conducted a series of experimental works to repair and strengthen beams with different flexural and shear damage levels using various repair/strengthening techniques such as carbon fiber-reinforced polymer (CFRP), steel plate (SP), and mechanical steel stitches (MSS). Within the scope of the study, post-strengthening performances of pre-damaged shear beams and flexural beams were investigated. For this, 1/2 geometrical scaled 20 reinforced concrete rectangular cross-section beams, with dimensions of 125/250 mm and a span of 2500 mm, were produced. Half of these beams (type-SB) were designed to meet shear damage due to insufficient shear reinforcement, while the other half (type-BB) was designed to undergo flexural damage (sufficient shear reinforcement). Subsequently, a reference beam was produced in both shear and bending test groups, the other beams were strengthened with different techniques, and four-point bending tests were performed. Reference (non-damaged) bending and shear beams were vertically loaded and comprehensive data for these specimens were obtained. Later, the flexural beams (type-BB) were vertically loaded until reaching mid-displacement/span length (δu/L) ratios of 1%, 2%, and 3% of the flexural reference beam, while the shear beams (type-SB) were loaded up to 50%, 65%, and 85% of the maximum load-carrying capacity (Pmax) of the shear reference beam to induce different damage levels. Then the specimens were strengthened with three strengthening methods (CFRP, SP, and MSS). The data obtained from the experiments were compared, considering each group specimen's strength, displacement ductility, stiffness, and energy dissipation capacity. In addition, the cost of each strengthening type was calculated, and the ratio of the strengthening costs / the production cost of the element itself was determined. According to load carrying capacity and ductility behavior, experimental studies have shown that CFRP has proven to be more effective for type-BB beams (3% pre-damaged level), whereas MSS has proven to be more effective for type-SB beams (85% pre-damaged level) than other methods. While both MSS and SP have been effective for all damage levels in BB beams, CFRP has only shown effectiveness for a damage level of 3%. In the case of shear beams, the load-carrying capacity has increased for various damage levels with CFRP, SP, and MSS. However, typical bending beam behavior was exhibited for CFRP 85%, SP 65%, and MSS 85% load levels. It was also determined that SP and MSS contributed to the ductility orientation for the 65% damage level. However, in terms of cost, CFRP was the most expensive, whereas MSS was the least expensive strengthening method. CFRP was approximately twice as costly as SP and three times more costly than MSS. Finally, due to its ease of application and low cost, MSS, which is a relatively new strengthening technique, has been found that the MSS method is a better alternative than other methods, especially for the strengthening of beams that have received shear damage. © 2024 Institution of Structural EngineersArticle Betonarme Çerçeveli Binaların Tasarımında Kullanılan Sonlu Eleman Programlarının Tbdy-2019’da Yer Alan Periyod, Taban Kesme Kuvveti ve Göreli Kat Ötelemesi Bağlamında Değerlendirilmesi(2022) Uysal, Yusuf; Aksoylu, Ceyhun; Arslan, Musa HakanGelişen yazılım teknolojisi ile birlikte tasarımcı, seçilen deprem yönetmeliğine göre yapının analizini paket programlar yardımıyla kolaylıkla yapabilmektedir. Deprem yükünün tespitinde en önemli aşama yapının doğal titreşim periyodunun belirlenmesidir. Yönetmelikler tasarımcının, basit periyot bağıntıları (amprik) ve fiktif kuvvetler altındaki deplasmanlara bağlı literatürde kabul görmüş yöntemlere göre hesap yapmasını istemektedir. Bu çalışmada SAP2000 ve ETABS analiz programları kullanılarak yapının doğal titreşim periyodu tespit edilmiş ve elde edilen periyod değerleri TBDY-2019’da verilen yaklaşımlardan elde edilen değerlerle karşılaştırılmıştır. Çalışmada İstanbul/Avcılar’da yapılacak olan 2-9 katlı çerçeve tipi betonarme binaların, ZA ve ZC zemin sınıfları için ETABS ve SAP2000 analizinden elde edilen periyot, taban kesme kuvveti ve göreli kat ötelemeleri karşılaştırılmıştır. Analiz programlarının periyot seçerken yaptığı hesap kabullerinden dolayı 4-9 katlı binalarda ETABS’da bulunan periyot SAP2000’de bulunan periyottan %9,5-40 kadar daha az sonuç vermiştir. Dolayısıyla yapıya gelen taban kesme kuvveti de aynı oranda değişmiştir. Ayrıca yalnızca SAP2000’de iki zemin sınıfı için yapılan analizler sonunda ZC zemin sınıfında elde edilen taban kesme kuvveti ZA zemin sınıfına göre %50-80 daha fazla olduğu görülmüştür. Göreli kat ötelemeleri ise ZA zemin sınıfı yerine ZC zemin sınıfı seçilmesi durumunda %49,2-92 kadar daha fazla elde edilmiştir. Sonuç olarak tasarımcılara yol gösterici olması amacıyla analiz programlarında yapılan hesap kabulleri açıklanmıştır.Article Citation - WoS: 14Citation - Scopus: 18Seismic Performance of Masonry Structures After 06 February 2023 Earthquakes; Site Survey and Fe Modelling Approach(Elsevier Sci Ltd, 2024-11-01) İzol, Rabia; Işık, Ercan; Avcıl, Fatih; Arslan, Musa Hakan; Arkan, Enes; Büyüksaraç, AydınThe Kahramanmaras, earthquake couple, which took place on February 6, 2023, is one of the biggest disasters T & uuml;rkiye has encountered in the instrumental period. While the effects of these earthquakes were felt primarily in 11 different provinces, they also caused significant effects in many other provinces. These two independent earthquakes of magnitude 7.7 and 7.6, which are rare in the history of literature, occurred 9 h apart and caused more structural damage. Serious losses of life and property occurred in Kahramanmaras,, the epicenter of both earthquakes. In this study, structural damages on masonry buildings in rural areas of Kahramanmaras, province are examined in detail within the framework of the cause-effect relationship. Different building samples are evaluated for each damage situation. In addition, nonlinear time history analyses were performed on a sample structure and the damage was examined in detail. In general, these structures, which do not receive engineering services, exhibit typical masonry structure damage as in other earthquakes. This study provides information about the behavior of such buildings under earthquake loads and emphasizes the importance of receiving the necessary engineering services for these structures.Article Citation - WoS: 2Citation - Scopus: 2Effects of Shear Wall Ratio and Location on Earthquake Performance of Reinforced Concrete Buildings Having Different Ribbed Slab Configurations(Elsevier, 2025-11-01) Uysal, Yusuf; Serdar, Ali; Aksoylu, Ceyhun; Arslan, Musa Hakan; Ecemiş, Ali SerdarThis study investigates the earthquake performance of reinforced concrete buildings designed with ribbed slab system. Analyses were performed on hypothetical models representing residential buildings in Gaziantep/Islahiye region. In this study, a total of 18 shear wall-frame structure models with three different shear wall placements in accordance with TBEC-2018 were analyzed. Wall density index (0.003, 0.005 and 0.008), shear wall locations defined as M1 (vertically placed on the outer axes), M2 (center-mounted), and M3 (parallel to the outer axes), and ribbed slab placements (parallel and staggered) are considered as variable parameters. The seismic performance of the structures was evaluated using linear and nonlinear analyses. Nonlinear static pushover analyses were used to compare capacity curves, overstrength factor, interstory drift ratios, base shear forces, overturning moments, and second-order effects for each model. As the wall density index increased from 0.003 (%25) to 0.008 (%75), the initial stiffness increased by 158 %, but this increase decreased the plastic deformation capacity and modal displacement values. Models M1 and M3 with walls positioned on the outer axes provided 20.53 % more load carrying capacity than Model M2 with the central wall. The uncracked section shell exhibited 19 %-83 % stiffer behavior, while the cracked sections absorbed more energy. No significant effect of the slab rib arrangement (parallel/staggered) on the stiffness and period was observed. As the shear wall ratio increased, the torsional period decreased by up to 55 %, and the highest torsional strength was achieved in Model M3. Low shear wall ratio models exceeded code drift limits and showed increased interstory drift differences. The results showed that shear wall placement and ratios are critical to seismic performance, and that TBEC-2018 effectively enhances safety in ribbed slab systems.Article Citation - WoS: 29Citation - Scopus: 32Code-Based Damage Assessment of Existing Precast Industrial Buildings Following the February 6th, 2023 Kahramanmaraş Earthquakes (pazarcık Mw 7.7 and Elbistan Mw7.6)(Elsevier Ltd, 2024-06-01) Arslan, M.H.; Dere, Y.; Ecemiş, A.S.; Doğan, G.; Özturk, M.; Korkmaz, S.Z.In Turkey, a substantial portion of the industrial buildings consists of precast structures. Unfortunately, these buildings suffered significant damage, with some partially collapsing, during two consecutive earthquakes that occurred in Kahramanmaraş (Pazarcık Mw7.7 and Elbistan Mw7.6) on February 6, 2023. Consequently, numerous industrial facilities became unusable, leading to substantial economic losses. This article aims to identify the vulnerabilities of such buildings and assess their actual earthquake performance to prevent potential future damages. The authors collected data through field investigations conducted near the earthquake's epicenter, which were subsequently evaluated within the study. The research comprehensively examines the seismic characteristics of both earthquakes, the structural system of existing prefabricated industrial buildings in the region, and the relevant provisions outlined in the history of earthquake codes for prefabricated industrial buildings. Additionally, nonlinear finite element simulations of the heavily damaged hinged type of column-beam connections commonly employed in earthquake-prone areas are presented. The impact of manufacturing defects on the structural seismic behavior is also investigated. In the study's final stage, it is concluded that non-compliance with structural projects and relevant codes during the manufacture of connection regions in prefabricated industrial buildings is one of the primary causes of structural damage. Furthermore, it is observed that necessary measures should be implemented in these structures to enhance lateral stiffness in the roof plane, and the use of hinged column-beam joints should be avoided or restricted, especially in regions prone to earthquakes. The finite element model analysis reveals that the load-bearing capacity of the connection increases by 62% for lateral out-of-plane loading when grout mortar is applied. © 2024 Elsevier LtdArticle Citation - WoS: 38Citation - Scopus: 48Detection of Damages Caused by Earthquake and Reinforcement Corrosion in Rc Buildings With Deep Transfer Learning(Elsevier Sci Ltd, 2023-03-01) Dogan, Gamze; Arslan, Musa Hakan; Ilki, Alper; Hakan Arslan, MusaThe Reinforced Concrete (RC) buildings in countries within earthquake zones like Turkey are generally damaged more than anticipated during earthquakes. Corrosion of reinforcement and other damages caused by the corrosion are also widely encountered in relatively old structures that have not received adequate engineering services. Although it is not easy to differentiate the earthquake and corrosion damages in some cases, the formation mechanisms of these damages and their consequences in terms of structural safety may be quite different. For this reason, in post-earthquake damage detections, it is important to determine the cause of the damage in a realistic way to plan the future interventions on the building (repair methodology, demolition / reconstruction, etc.) properly and to accurately decide on the financial schemes for required interventions (insurance, government support, owner, etc.). In this sense, smart systems are needed to be activated to speed up the decisionmaking process of the engineers/technical staff to be involved in field damage assessment surveys after earthquakes. Based on this motivation, a Deep Transfer Learning algorithm was developed in this study, which allowed distinguishing of damages caused by corrosion from earthquake-induced damages in structural elements of RC buildings. This study, which was conducted for the first time in the literature, tested the performance of Deep Transfer Learning method in damage detection and classification efforts of RC structural members. For development of the algorithm, a data pool was used consisting of images belonging to 1040 damaged RC elements, mostly columns, obtained from field surveys conducted after Istanbul-Silivri (Mw = 5.8) earthquake dated 26.09.2019 and Elazig-Sivrice (Mw = 6.8) earthquake dated 24.01.2020. The developed algorithm can determine whether the damage was caused by earthquake or reinforcement corrosion with an estimate success of 90.62 % based on damage image. Additionally, at the end of the study, classification performance of developed algorithm was also tested by using different data pool from Samos Earthquake dated 30.10.2020 (Mw = 6.6). It has been seen that the algorithm makes damage type predictions with high success in the new data set.Article Citation - WoS: 65Citation - Scopus: 72Investigation on Improvement in Shear Performance of Reinforced-Concrete Beams Produced With Recycled Steel Wires From Waste Tires(Mdpi, 2022-10-17) Aksoylu, Ceyhun; Özkılıç, Yasin Onuralp; Hadzima-Nyarko, Marijana; Isik, Ercan; Arslan, Musa HakanIn parallel with the increase in vehicle sales worldwide, waste tires are becoming an increasing problem. The storage and disposal of these waste tires are critical environmental problems. Re-using these wastes in different areas instead of being disposed of is vital in preventing environmental pollution and creating new low-cost products. From this motivation, this paper investigates the properties of traditional reinforced-concrete beam with recycled steel wires (RSWT) obtained from the waste tires. RSWT were added to reinforced-concrete beam between 1% and 3% by weight with an increment of 1%. In total, 9 cubes, 12 cylinders and 12 reinforced-concrete beams were cast and tested to obtain the compressive, splitting tensile and flexural strengths, respectively. RSWT added to the concrete by 1%, 2% and 3% increased the compressive strength by 17.2%, 30.8% and 46.4%, respectively, compared to the reference concrete. In split tensile strength, 14.4%, 25.1% and 36.7% increases were observed, respectively. This showed that there was an effective increase in the compressive and tensile strength of concrete with the increase of fiber content. Although the effect of fiber content in samples with high stirrup spacing (27 cm) provides significant benefit in improving the beam behavior, the effect of fibers was more limited as the stirrup spacing decreased (20 cm and 16 cm). An approximation of over 91% was obtained between the analytical calculations and the experimental results. This shows that the analytical calculations given in the standards can be used for new experimental studies.Conference Object Weight Analysis of Plane Steel Roofs(2019) Akyüz, Abdullah; Arslan, Musa HakanIn this study, the parameters affecting the weight of the plane steel roofs, which will be designed with steel, which is widely used in the world and in our country, are examined. In the light of current knowledge and experience, 6 parameters were determined and 192 different account models were created in order to see the effect of each of these parameters separately. These account models were analyzed by SAP2000 program and the weight values obtained were noted. According to the results, the effect of each parameter on the weight of the steel roofs was determined. In addition, the results obtained by the calculations were tried to be estimated with the help of intelligent systems and the results of these systems were investigated.
