Pushover Analysis of Steel Structures with Different Plan Configuration

Steel is by far most useful material in construction and played an important role in last few decades. It must necessary to analyze and design a structure to perform well under seismic loads and also endow with well strength, stability and ductility for seismic design. The seismic performance of a multi-story steel frame structure is analyzed according to the provision of current Indian code (IS 800-2007), seismic data and seismic factor from Indian code (IS1893-2016). Few guidelines like Applied Technology Council (ATC40) and Federal Emergency Management Agency (FEMA356) have used. The study of Steel Structures with different plan configuration is very essential now a day, as it will help to understand the behaviour of the structure in certain circumstances. In this study typical G+4 story Steel frame buildings have been analyzed, for different plan configuration in one direction i.e. in X- direction. In this work different models were prepared with different span length of frame and Performance of each frame is studied through pushover analysis. In the present study, four different types of model analyzed using pushover analysis in x & y direction respectively. The pushover analysis has been carried out using Etabs 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 and story drift.
