Static Push Over Analysis of a 5 Storey Steel Building

Abstract

The use of steel structures has been increasing rapidly in recent years. This is due to the high strength and ductility of the steel. This makes steel stand out compared to concrete for earthquake resistant building design.The seismic performance of a multi-story steel frame structure is analyzed according to the provision of current Turkish Eartquake Code (DBYBHY 2018). Few guidelines like Applied Technology Council (ATC40) and Federal Emergency Management Agency (FEMA356) have used. Steel bracing is very useful for increasing the shear capacity of the structure. The use of steel brace is one of the most common methods to increase the earthquake resistance of buildings. In steel structures, the steel brace arrangement is arranged in two ways, concentric and eccentric. There are few possibilities to arrange steel bracings such as X, V, Diagonal, K (Concentric bracings) and some eccentric bracings as well. In this study typical 5 storey steel frame buildings have analyzed, for X and invert V types of concentric bracings. Performance of each frame is studied through pushover analysis. The pushover analysis has been carried out using SAP2000 v18, a product of computer and structure international. The results of all models are analyze and compare in term of base shear, story displacement, pushover curve, spectrum curve, performance point of the structure.
