摘要
介绍了两榀高效预应力混凝土 (HPC)叠合框架和 1榀 (RC)整浇框架模型试验 ,并对试验结果进行了比较。分析了 HPC叠合框架在水平低周反复荷载作用下的受力特点、裂缝开展、延性指标、耗能能力及破坏形式 ,为 HPC叠合框架结构在地震区的应用提供了试验依据。
In this paper,the model test of two pieces of HPC omposite frame and one piece of RC frame are introduced. Compared with the results of two test specimens,the seismic behavior of HPC composite frame under laterally reversed low-cyclic loading is discussed.Testing results for following factors are analyzed:the mechanics characteristic,the crack propagation,the ductility target,the engergy consumption,the failure shape,and so on.A basis for the application of HPC composite frame in the seismic region is presented.
