Structural Behavior of a Steel Grid Shear Wall Subjected to Combined Axial and Cyclic Lateral Loads

Abstract:

The effects of earthquakes can be devastating especially to existing structures that are not based on earthquake resistant design. This study proposes a steel grid shear wall that can provide a sufficient lateral resistance and can be used as a seismic retrofit method. An experiment was performed on reinforced concrete (RC) frames with and without the steel grid shear wall proposed in this study. These frame specimens were subjected to combined axial and cyclic lateral loads that were applied by using two actuators with a maximum capacity of 500 kN and a single actuator with a maximum capacity of 2,000 kN, respectively. The experimental results showed that the RC frame specimen with the proposed shear wall retained high lateral strength and ductility.
