摘要
以2榀3层单跨混凝土框架结构为研究对象,通过低周反复加载试验,分别从试验现象、破坏特征、滞回曲线和变形性能等方面进行了描述和分析。分析结果表明,3层混凝土框架结构具有良好的抗震性能。此外,还利用自编的框架结构非线性分析程序,对试件进行了骨架曲线的计算分析,结果与试验吻合较好;通过改变某些参数,计算了试验未研究的一些情况,为3层框架结构的分析提供了有用的结论。
In this paper two 3-story single-span R C frame structures are taken as research objects. According to the results of cyclic loading tests, several aspects, such as the test phenomena, failure characters, hysteretic curves and deformation performances, are described and analyzed. Analysis results show that 3-story R C frame structures have good seismic performances. Besides, a frame structure nonlinear analysis program is used to give out the computed envelopes of the testing members, through which the coincidence of computed and test results can be seen. By changing some parameters, the program also studies other traits of R C frame structures untested, which provide useful conclusions for the analysis of 3-story frame structures.
