摘要

通过利用混凝土边框对钢筋混凝土核心筒进行约束,形成带边框的混凝土核心筒,并采用高宽比为3.14的大尺寸试件进行拟静力试验,研究其破坏机理、滞回性能、承载力、弹塑性变形能力、刚度退化及耗能能力等方面的抗震性能。试验结果表明,设置混凝土边框约束是改善筒体抗震性能的一项有效措施。
A large scaled specimen of the concrete core wall with aspect ratio of 3.14,confined with reinforced frame,was tested under pseudo-static loadings to investigate its seismic behavior including the failure mechanism,hysteretic behavior,load-carrying capacity,elasto-plastic deformation ability,stiffness degradation and energy dissipation capacity.The test results show that the measure of the confinement with reinforced frame can improve the seismic behavior of concrete core wall effectively.
