Computer simulation study on hysteretic behavior of composite steel frame-reinforced concrete infill wall structure

The composite steel frame-reinforced concrete infill wall structure is considered as a new type of earthquake-resistant system with brilliant future of application. In order to study the hysteretic behavior of the structure, a large scale specimen under cyclic load was conducted and then the computer simulation models were established using the software ANSYS. By comparison, the computer calculated results matched the experimental results well showing that the computer simulation is feasible. Based on that, the structural behavior was evaluated from four aspects: strength, stiffness, load distribution, ductility and energy dissipation. The analytical results indicate that the structure has ample lateral bearing capacity and high safety factor. The structure has good performances on ductility and energy dissipation. Finally design recommendations are presented.
