摘要
通过设置K型砼折曲撑以及其他型式支撑的两层框架和不设支撑的纯框架在低周反复荷载下的试验,着重研究了折曲撑框架的变形能力、延性系数、阻尼比等抗震耗能性能,以及其刚度和破坏机制。试验表明,折曲支撑是很好的消能抗侧力构件,且具有空间开敞。自重轻等特点。本文根据试验分析,提出了设计原则和建议。
The seismic behaviour of energy consumption, including deformation ability,ductility,damping ratio etc.,as well as the rigidity and the mechanism of destruction of RC frame braced by bent-bracing are studied by experiment on seven two-story frames, among which six are braced by type K bent-bracing and one is without bracing. under low frequency cyclic loading. The experiments show that bent-bracing, which has the features of being open in space and light in weight, forms a very good member for consuming energy and in resisting lateral force. The principles and suggestions on design are also presented in this paper.
