建筑隔震结构时程分析新方法
|
摘要
提出了一种在Matlab的Simulink环境下,对建筑隔震结构进行建模和时程分析的新方法。首先将隔震层简化为双线性模型,分析了地震作用下隔震层的各状态关系,并在Stateflow工具箱中进行建模,将上部结构视为串联多自由度体系,根据模型状态方程建立了多质点隔震结构的仿真程序。将程序应用于某文献实例并与之对比,证实了该方法的可行性和有效性。
A new model and analysis method for base - isolated structures is put forward in the SIMULINK environment of a Matlab tool. Firstly, base layer is simplified to bilinear hysteresis system, and variant states of the base layer is analysed, and modeled, then superstructures is modeled and corresponding programs are established using system model of multi - degree - freedom in series. At the final of paper, an numerical case example is given as compared to literal results, Compare results show the method's feasibility and reliability.
