Abstract

COUPLED- SHEAR WALLS are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. The lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. The structures located in near- source region behave differently compared to those in near-source sites when subjected to earthquake. Therefore, it is very important to study the behavior of these walls under near-field seismic loads. To do this, after validation of the finite element model with experimental sample; coupled-shear walls in 10 and 20 story buildings with l/h ratio (l=span length and h =beam height) of 2/0.7, 2/1, 2/1.75 and were modeled in Abaqus computer software. The NONLINEAR TIME HISTORY ANALYSIS were carried out using two coupled near and far fault records and then the performance of walls were studied under NEAR- FIELD EARTHQUAKE. The results show that the structural demands are higher for structures in near-field area in comparison to those for far- field. Besides, the effects of near- fault earthquake decrease when the coupled beam height and structural natural period increase.
