An Analytical Study About the Use of Steel Plate Shear Walls To Improve Lateral Rigidity of Reinforced Concrete Framed Structures
(LATIN AMER J SOLIDS STRUCTURES, 2020) Korkmaz, Serra Zerrin
Steel plate shear walls are becoming popular for steel structures. In this study, the use of Steel Plate Shear Walls (SPSW) was discussed to increase the horizontal stiffness of reinforced concrete structures. It was aimed to fix the SPSW elements to the exterior of the building. ABAQUS models of SPSW applied 2D frame samples, which were tested in a previous experimental study, were created. Experimental and analytical horizontal load-top displacement curves were found to be in good agreement. In the study, ABAQUS models of a 6-story and 3D reinforced concrete building were also created. In models, SPSW elements were placed at the exterior of the building. The load capacities of the reinforced and non-reinforced building models were compared. The steel sheet thickness and the number of frame openings at which the SPSW element was placed were considered as the variable parameters.

The Glocalisation of Istanbul's Retail Property Market
(EMERALD GROUP PUBLISHING LTD, 2022) Eren, Fatih; Henneberry, John
Purpose The continuation of globalisation and liberalisation processes has prompted the restructuring of many national and local property markets. The research examines the evolution of Istanbul's retail property market to identify how global and local agents engage with one another to produce a unique glocalized outcome. Design/methodology/approach The morphogenetic approach is adapted and applied to analyse the dynamics of market change. The focus is on the character and behaviour of national and international market actors and how they interact with the wider political economy. The research uses a combination of elite interviews, document analysis and corporate case studies to obtain empirical evidence. Findings The liberalisation of the Turkish economy heralded the entry of the first international companies into Istanbul's retail property market in the 1990s. International involvement expanded rapidly after 2004, accelerating the process of market re-structuring. However, while the number of global buy-outs increased, the expansion of local property companies-and the establishment of some international/national corporate partnerships-was even more marked. This resulted in a glocalised market with a strong and distinctive local culture. Originality/value Istanbul has been a major centre of trade for millenia. This is the first substantive analysis of the recent restructuring of the city's retail property market. Previous research on market maturity and market evolution has paid limited attention to the dynamics of change. The paper describes the use of a process-based theoretical framework (morphogenesis) that was explicitly designed to analyse structural shifts in socio-economic conditions through an examination of the characteristics and behaviours of the actors involved.

Hybrid Composite Board Produced From Wood and Mineral Stone Wool Fibers
(North Carolina State University, 2022) Akkuş, Memiş
Wood fiberboards are used extensively, mainly in the fields of furniture production, interior fittings, construction, etc. Mineral stone wool materials are used for heat and sound insulation in the construction industry. This study aimed to produce a new hybrid-based composite material by mixing fibers obtained from wood and mineral stone wool. For this purpose, hybrid fiberboards with 50, 40, 30, and 20% stone wool addition and a fiberboard group consisting of 100% pine and beech fibers (control sample) were produced in a hot press using thermoset-based urea formaldehyde and phenol formaldehyde resins. Statistical comparisons of the results were made for values of density, thickness swelling, and water absorption extents after 24 h immersion, bending strength and modulus of elasticity in bending, tensile strength perpendicular to the board surface (internal bond strength), and time to ignition (TTI) analysis. Additionally, percentage of mass loss (PML), average heat release rate (A-HRR), average effective heat of combustion (A-EHC), and mass loss rate (MLR) were studied. The results showed that as the stone wool content in the produced boards increased, the mechanical properties and thickness swelling decreased. The combustion results showed that the combustion resistance of the boards increased with increasing stone wool ratio. © 2022, North Carolina State University. All rights reserved.
The Impact of Sun Hour and Sky View Factor on Hospital Buildings Design: a Parametric Design Analysis in Konya, Turkey,
(2024) Özdemir, Hüseyin; Çakmak, Bilgehan Yılmaz
During the initial phases of hospital design, consideration of parameters such as sun hour and sky view factor can profoundly impact the well-being of patients and healthcare personnel. This study examines the use of parametric design techniques, facilitated by Rhino and the Grasshopper plugin, to create an algorithm for evaluating the effects of sun hour and sky view factor parameters on the health and well-being of patients and healthcare personnel. The algorithm aims to analyze the impact of solar hours and sky view factor parameters on the design of hospital buildings in Konya, Turkey. For this purpose, Numune Hospital, City Hospital, and Selçuk University Faculty of Medicine Hospital in Konya were selected for analysis. The identified hospital buildings and their built environments were modelled to scale for analysis. The study found that sun hour and sky view factor levels were higher in outward-facing blocks of the examined hospitals, while they were lower in lower-rise blocks that were closer together. The research suggests that taking into account sun hour and sky view factor parameters during the design of hospital buildings can assist designers in making informed decisions at both urban and architectural scales.

Optimal Energy Design and Retrofit Recommendations for the Turkish Building Sector
(COLLEGE PUBLISHING, 2021) Sayın, Selçuk; Augenbroe, Godfried
This paper introduces methodologies and optimal strategies to reduce the energy consumption of the building sector with the aim to reduce global energy usage of a given region or country. Many efforts are underway to develop investment strategies for large-scale energy retrofits and stricter energy design standards for existing and future buildings. This paper presents a study that informs these strategies in a novel way. It introduces support for the cost-optimized retrofits of existing, and design improvements of new buildings in Turkey with the aim to offer recommendations to individual building owners as well as guidance to the market. Three building types, apartment, single-family house and office are analyzed with a novel optimization approach. The energy performance of each type is simulated in five different climate regions of Turkey and four different vintages. For each vintage, the building is modelled corresponding to local Turkish regulations that applied at the time of construction. Optimum results are produced for different goals in terms of energy saving targets. The optimization results reveal that a 50% energy saving target is attainable for the retrofit and a 40% energy saving target is attainable for new design improvements for each building type in all climate regions.

PLACES OF THINKING AND SELF EVALUATION: ANATOLIAN ÇILEHANES
(2021) Kurnalı, Melih; Koca, Duygu
The basis of the idea that originates the existence of architectural spaces underlies a function or to meet the needs and requests of the user. These functions emerged ontologically from basic needs and then diversified. However, thinking function has not been evaluated within these basic needs. Although there is no specialized area of study for spaces devoted to thinking within the architecture and interior design discipline, the main aim of this study is to investigate the historical existence and to determine their basic features of thinking spaces. In this context, the study first makes a conceptual analysis of thinking in space and specialized places or thought. In the second part, the thinkingbased spaces in Eastern civilization and the buildings realized by the reflections of similar cultures are focused. After these investigations, Çilehane buildings and their interiors, which are special structures, used for thinking within several belief systems seen in Anatolia are examined. In the field study, the aim is to define the architectural and spatial characteristics of Çilehanes. The thought process intrinsically is associated with solitude and serenity and thus requires isolated environments. The study tries to reread the definitions made in the existing literature about the thinking spaces through the architectural and spatial formations of Çilehanes. The 10 cases of Çilehanes belonging to various belief systems in Anatolia form the context of the study. The cases are examined by a formal analysis method through four criteria: the building mass, facade organization, the openness-closeness character of interiors, and interior features. The result of the research shows that the examined Çilehanes have universal characteristics for the thinking function. The main characteristics of the buildings and the interior spaces such as being far from the society and the city, located in forests, waterfront or mountainous areas, having single volume, and minimum equipment correspond to the significant principles of thinking places.
