| 摘 要： | 结合对震后损伤框架结构在反复荷载作用下刚度退化的研究是结构抗震分析的重要内容,通过对一层一跨的框架结构施加低周反复荷载试验,得出了结构构件的抗震滞回特性,同时,对框架结构构件的刚度退化情况做了计算和分析,从而为建筑物加固方法的确定奠定了理论基础。

| Abstract: | Combining with the fact that the research on the stiffness deterioration of damaged frame structure after earthquake is the important content for the structural seismic analysis,the paper by having the low-cyclic loading tests on the frame structure,concludes the seismic hysteresis features of the structural components,and calculates and analyzes the stiffness deterioration of the frame structure,so as to lay the theoretic foundation for identifying the intensification method of buildings. |
