Abstract :

Buildings with wall or frame-wall systems are more effective against earthquake forces and sustain less damage than buildings which their lateral resistance is solely depends on frames. Four reinforced concrete (RC) structural wall specimens were subjected to cyclic loading using finite elements method with ABAQUS software in order to study influence of diagonal web reinforcement. The research parameters included the amount and configuration of reinforcing bars in the web. The conventionally reinforced wall failed due to web crashing with an abrupt drop in load capacity, whereas the walls reinforced with diagonal web reinforcement failed in a more ductile mode. The results clearly indicates that the diagonal web reinforcement increase the lateral load capacity of wall. The energy dissipation capacity of the diagonal web reinforced is superior to the conventionally reinforced wall.
