Title:         Seismic Evaluation and effect of shear wall of high-rise buildings using drift control
Authors:   Abdul Qadir Bhatti
Abstract:  Shear wall is a technique used to control lateral drift in structures subjected to seismic and wind forces. Shear wall adds stiffness to the building which in turn reduces lateral drifts. The two important aspects regarding shear walls are its location in the building and the thickness used by the designer.
In order to visualize the effectiveness of shear wall 3 case studies of existing structures have been performed. Location and thickness are the variable parameters in each case study. Each case study is carried out in 3 phases. Modeling is done followed by detailed configuration of the building. Response spectrum analysis is performed due to irregularities in structures and seismic intensity. The results are tabulated and expressed in the form of graphs. These graphs relate the maximum lateral drift against the floor number when subjected to seismic loads.
The best possible case is selected on basis of economy and parameters specified above. It is then compared with original building to see the optimization and economy that would have been achieved if this case would have been implemented on site. What we have seen is that 6” shear wall yields better results than 12” shear wall in all case studies. This results in better economy, ductility and satisfies all the drift limits of BCP 2007.
