초록

In recent years, earthquake resilient structures have become a research focus in the field of seismic engineering. In order to improve the resilience of steel frame - concrete wall panel structures, an innovative self-centering SRC wall panels with replaceable energy dissipaters is presented in the paper. For this purpose, the tested subassembly involving the self-centering SRC walls with frame beams as boundary was presented. The wall panels used in steel moment frames can provide the lateral resistance for structures. Test models of the wall panels with partial framed beams as boundary were suggested. The full-scale specimens were tested under cyclic lateral loads. The configuration of energy dissipaters and initial force of PT steel bars were varied to study their impacts on lateral behavior of the walls. Furthermore, the numerical models based on ABAQUS were developed. The parameter studies, including diameter of PT tendons, beam profile, beam span and wall width, were then conducted. The PT tendons can provide self-centering ability and the dampers are used to dissipate energy. The failure of the wall panels is mainly concentrated on energy dissipaters. This case makes it possible to repair the walls easily.
