| Abstract: | According to the abroad study results, an E-shape steel damper that mild steel was replaced by high-strength steel was designed. The restoring force model of E-shape steel damper was studied through tests and numerical a-nalysis. The results of test and simulation showed that the damper has a good hysteresis loop curve between force and dis-placement under cyclic loading adopting an ideal elastic-plastic model. The analysis also showed that this design method could be applicable to high-strength steel and reduce production cost obviously. |
