Seismic Behavior in different section reinforced concrete shear walls

This paper aims at comparing the seismic behavior of straight linear shear wall and L-shaped shear wall. In order to investigate the seismic behavior, hysteretic diagrams of both types of wall under cyclic loading have been drawn since the hysteretic diagrams are the best reflexive diagrams of the seismic behavior of the structural parts under the seismic loading. The research methodology includes modeling or simulating seismic behavior of the concrete walls that have been modeled by ABAQUS (FEM). To make sure of the accuracy of the modeling process and its parameters, data verification has been performed by comparison of the results of limited laboratory elements' analysis. The results of this study indicate that after modeling, analyzing, and drawing the hysteretic diagrams in the considered wall model, the straight linear wall behavior shows more ductility than the L-shaped wall. It is due to that fact that creating concentrated torsional tensions on the corner of L-shaped wall can decrease the concrete's ductility and strength in this region and have a more brittle behavior than the straight linear walls.
