摘要: 在弯剪扭复合受力下,对2根普通混凝土构件和2根再生混凝土构件进行抗震性能试验,对再生混凝土复合受扭构件的破坏形态、滞回曲线、耗能能力、延性等进行分析。研究表明,再生混凝土复合受扭构件的抗震性能比普通混凝土的稍差,但基本能够满足抗震设计的要求。

Abstract: In this paper,seismic behavior of 4 members,two of them made of recycled aggregate concrete and the other made of RC,is studied under low frequency reversed moment,shear and torsion. The failure features,the hysteresis loops and the ductility under seismic loads are comparatively investigated. The test and analyses show that the seismic behavior of members including the ductility with recycled concrete is slightly lower than that of members with conventional concrete and both of them can meet the requirements of the code for seismic design of buildings.
