seismic assessment of concrete shear wall with rectangular openings in near fault earthquake

in this study, effect of rectangular opening in different sizes and variant locations on concrete shear wall ductility and their base shear, maximum displacement as well as energy dissipation in near fault earthquake is investigated. in this investigation the model of concrete shear wall is performed using abaqus finite element software. the results of numerical study are validated with results of experimental test. there is a good agreement between results of numerical model and experimental test. the openings have area of 0.1, 0.2, 0.25 as well as 0.3 shear wall area. they are also located in center, up and right of concrete wall and up and right side of concrete wall. the models are subjected to two near fault earthquake records. energy absorption, base shear and maximum displacement of models are compared. results indicated that openings decrease energy absorption, base shear and lateral load carrying capacity. also behavior of shear wall was sensitive about location of opening.
