在反复荷载作用下的混凝土应力-应变全曲线是深入研究抗震结构中钢筋混凝土构件恢复力特性及其延性的重要依据之一。近年来,随着电子计算机的发展,对构件进行非线性全过程分析提供了条件,而应力-应变全曲线则是必不可少的基本数据。本文通过试验研究五种形式反复荷载作 The full stress-strain curve of concrete subjected to repeated loads is an important basis for further research on the restoring force characteristics and ductility of reinforced concrete members in seismic structures. In recent years, with the development of electronic computers, conditions for the nonlinear full-process analysis of components have been provided, and the stress-strain curve is an essential basic data. This article through the experimental study of five forms of repeated loading
