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。 By setting up the two-story frame with K-type buckling brace and other type of support and the pure frame with no support under the low cyclic reversed load test, the deformation capacity, ductility coefficient, damping ratio, etc. of the flexural bracing frame were studied emphatically. Energy performance, as well as its stiffness and failure mechanism. The test shows that the flexural support is a good energy dissipation and anti-lateral force component, and has a space openness. Light weight and other characteristics. This article proposes design principles and recommendations based on experimental analysis.
