Comparing the effect of earthquake on high rise buildings with & without shear wall and flanged concrete column using STAAD Pro


Sumit A Paul, Amey R Khedikar

Earthquake never kills people but the defective structures do. The stability and stiffness of any structure is the major issue of concern in any high-rise buildings. Shear walls are structural members which resist lateral forces predominant on moment resisting frame. Shear walls are most preferred structural walls for earthquake resistance. This research is related to comparison of shear wall type structure with moment resisting type of building. The present study states three type of models, moment resisting frame, Shear wall building concentrically located along X- axis on outer periphery of building and Concrete column flange concentrically located on outer periphery along the X-axis. Models of the three structures with same loading were created on STAAD. Pro and were analyzed and further they were compared for their suitability. For 10 storey building and 3 bays along X-axis of 4m each and 4 bays along Z-axis of 4m each were considered and loads were applied as per the IS specifications. The analysis was conducted as per the specifications of IS standards IS 13920, IS 1893, IS 875, IS 456. From the result it is seen that there is decrease of approximately 10% in Lateral storey shear and Base shear when the moment resisting frame was introduced with shear wall. Thus, possessed 10% less lateral force and base shear. The results of Axial force, bending moment, Node displacement were found satisfactorily less than the moment resisting frame. If cost is been compared, then can be stated as conomical in all sense since for the same configuration and load it greater stability and stiffness as checked from the node displacement results.
