摘要:
通过对K型高强组合钢偏心支撑的有限元分析,得出结构的滞回曲线,从而得到结构的骨架曲线,以及退化刚度,最后给出结构的恢复力模型.最后,进行了骨架曲线模型和有限元分析得到的骨架曲线的对比, 并且通过另外两种不同强度钢材组合的偏心支撑支撑对此恢复力模型进行了验证,结果表明,得到的恢复力模型可以良好的表达K型高强组合钢偏心支撑的初始刚度,各个阶段的刚度退化等特征.
Abstract:
Based on the finite analysis of the EBF, the hysteretic curve, skeleton curve and deteriorating stiffness curve of high strength combination steel structure obtained, and the restoring force model was derived as well. Comparing the restoring force model with the skeleton curve result in the finite analysis, the author proved this restoring force model by using two other EBF. The results showed that the storing force model in this paper could express the feature of the K-EBF excellently
