| 摘 要： | 本文对1根普通混凝土柱和4根全再生混凝土柱模型进行了低周反复荷载试验研究,模型按1/2缩尺。在试验基础上,分析了其承载力、刚度及其退化过程、滞回特性、延性、耗能能力、破坏形态等。研究表明:随着配筋率的增加,再生混凝土柱的承载力、刚度、耗能能力均有提高;同时,建立了基于再生混凝土强度折减的承载力实用计算方法,其计算结果与试验结果符合较好。

| Abstract: | A series of laboratory experiments of five 1 /2 scale columns under cyclic loading action were performed.Among 5 columns,one is a natural concrete column and four are recycled concrete columns.Load-carrying capacity,stiffness and its deterioration process,hysteretic loop,ductility,energy dissipation and failure patterns were analyzed on the basis of the experiments.A practical method of load-carrying capacity calculation based on concrete strength reduction was proposed.Our results show that,with the increa... |
