| Abstract | ||
| Executions of the shear walls along the exterior perimeter of slender high rise buildings enhance the efficiency of such buildings to resist the seismic forces. But uncertainties in the locations of shear walls are very high because of the demandable architectural openings (windows – doors) in the exterior views of such buildings. So, this study presents a considerable interest in establishing design guide lines for numerical investigation of seismic response of shear walls taking into account such openings and their locations. Five three dimensional models of different configurations of the openings are chosen and compared to figure out the best installation of openings having more efficiency on the performance of shear walls under earthquake excitation. Computer generated models are analyzed by SAP2000 program[11] and the loading is considered using acceleration time history with a peak ground acceleration 0.25g provided in the new Egyptian code (ECOL2008)[13] for seismic loads on structures and building works. The comparative results showed that the top displacement, base shears and stress distributions around the openings depend on the openings arrangement system. The results of staggered opening system in the shear walls (spatial arrangement) are very much close to those resulted in the shear walls without openings than the other opening arrangement cases. Finally the staggered arrangement of openings between the stories in shear walls are suggested to be applied in engineering practice since it satisfies both the architectural and seismic requirements. | ||
