摘　　要：通过对纤维增强混凝土(HPFRC)耗能墙-钢筋混凝土(RC)框架结构试件的拟静力试验发现,该新型抗震结构的滞回曲线较为饱满,耗能能力较好,HPFRC耗能墙显著增加了RC框架结构的耗能能力;HPFRC耗能墙-RC框架结构达到峰值荷载点时,仅产生中度损伤;HPFRC耗能墙-RC框架结构具有良好的延性和抗震性能。基于HPFRC耗能墙-RC框架结构的拟静力试验结果,采用理论分析结合试验数据回归的方法建立HPFRC耗能墙-RC框架结构的四折线恢复力模型,为该新型抗震结构的动力弹塑性分析提供参考。Through the quasi-static test of the fiber reinforced concrete(HPFRC)energy dissipation wall-reinforced concrete(RC)frame structure,it is found that the hysteretic curve of the new seismic structure is relatively full and the energy dissipation capacity is well,and the HPFRC energy dissipation wall significantly increases the energy dissipation capacity of RC frame structure,when the HPFRC energy dissipation wall-RC frame structure reaches the peak load point,only moderate damage occurs;HPFRC energy dissipation wall-RC frame structure has good ductility and seismic performance.Based on the quasi-static test results of HPFRC energy dissipating wall-RC frame structure,the four fold restoring force model of the new seismic structure is established by theoretical analysis and regression of test data,which provides some reference for the dynamic elastic-plastic analysis of the new seismic structure.
