Abstract:
Using shear walls as an earthquake resistant system in reinforced concrete structures enjoys prominent position among civil engineers in recent years. As most produced stress and damage occurs at the edges of shear wall under combination of vertical and lateral loads, it is expected that seismic behavior of shear walls can be improved by using boundary element at their edges and considering special reinforcing rules. In this thesis, the effect of boundary element details and parameters on seismic behavior of shear walls has been evaluated by a finite element model. By comparing the results with parameters specified in codes, the modeling parameters and performance levels given for shear walls has been investigated. The results demonstrate that in different aspect ratios, making small changes at the edges of shear walls, i.e. transverse and longitudinal reinforcement arrangement, can improve the characteristics of shear¬ wall behavior such as lateral resistance or ductility, even up to 2 times
