Abstract: Recently there has been a considerable increase in the number of tall buildings, both residential and commercial, and modern trend is towards taller structures. Flat slab/plate is most widely used systems in reinforced concrete construction in offices, residential and industrial buildings in many parts of the world. This system having advantages that it reduces cost of form work and construction time, easy installation and requires the least story height. The flat plate system, in which columns directly support floor slabs without beams. Shear walls are relatively thin, vertically deep reinforced column used in structure which provide stability to structures from lateral loads like wind, seismic loads. In the present work, the effect of with and without shear wall of flat slab building on the seismic behavior of high rise building with different position of shear wall studied. For that, 15 story model is selected. To study the effect of different location of shear wall on high rise structure, linear dynamic analysis (Response spectrum analysis) in software ETABs is carried out. Seismic parameters like time period, base shear, storey displacement and storey drift are checked out.
