摘　　要：通过对纤维增强混凝土耗能墙-钢筋混凝土框架结构试件的拟静力试验发现,HPFRC耗能墙能够显著增加RC框架结构的耗能能力.试验表明,HPFRC耗能墙-RC框架结构中的RC框架与HPFRC耗能墙是由两种性能差异较大的材料制作,故在相同的特征荷载点(如开裂、屈服、峰值荷载点)处,两种构件的损伤状态和刚度退化明显不同,计算这种结构的水平承载力时,应分别考虑这种差异.通过理论分析提出了HPFRC耗能墙的各特征点荷载计算式,为下一步HPFRC耗能墙-RC框架结构各特征点荷载的计算提供依据。Through the quasi-static test of HPFRC energy dissipation wall-RC frame structure,it is found that HPFRC energy dissipation wall can greatly increase the energy dissipation capacity of RC frame structure.The test shows that the RC frame and HPFRC energy dissipation wall are made of two materials with different performance.Therefore,at the same characteristic load point(such as crack,yield,peak load point),the damage state and stiffness degradation of the two components are obviously different.This difference should be considered respectively when calculating the horizontal bearing capacity of this structure.The calculation formula of characteristic point load of HPFRC energy dissipation wall is put forward through theoretical analysis,which provides the basis for the calculation of characteristic point load of HPFRC energy dissipation wall-RC frame structure in the next step.
