摘要
对新型钢连梁控制结构进行分析,确定动力分析模型,考虑材料非线性因素,应用有限元分析软件对空间简化分析模型进行弹塑性动力时程分析,通过3种连梁方案的对比,考查钢连梁控制结构连梁方案在强震作用下对结构体系抗震性能的影响.分析结果表明,钢连梁控制结构可以在不改变结构体系自振特性的情况下有效控制结构的地震反应,使结构体系趋于理想的耗能模式,具有优越的抗震性能.
This Thesis devises a new type of steel coupling beam with control device. Conceptual analysis was carried out on it, with its model for dynamic analysis identified, elastic-plastic time history analysis was performed to assess the efficiency of the innovative structure to reduce lateral seismic response of buildings under severe earthquake. Results show that the innovative steel coupling beam with control device demonstrates considerable seismic performance, which could reduce lateral seismic response of buildings while keep its natural vibration properties so as to make the structure serve in an ideal dissipation mode.
