结构抗震控制的动态仿真分析方法研究

介绍了结构抗震控制的仿真分析方法:将设置阻尼器的结构看作一受控系统,运用状态空间方法描述受控结构的运动微分方程,采用MATLAB中的SIMULINK工具箱进行动态仿真,得到整个受控结构在地震作用下的动态反应。文末给出了仿真分析算例,其分析结果表明采用SIMULINK能够有效、准确地分析设置非线性阻尼器的结构在地震作用下的动力响应。

Research on the Method of Dynamic Simulation for Seismic Controlled Structures

Dynamic Simulation Method is used to analyze the seismic controlled structures in the paper, which focuses mainly on the procedure of dynamic simulation by the SIMULINK program. Structure with non-linear dampers is considered as a controlled system described by the dynamic differential equation in state-space method, then simulated dynamically by using SIMULINK BOX in MATLAB program and its dynamic responses under the action of frequently occurred earthquake and seldomly occurred earthquake can be obtained. A practical example is also shown in the paper, which illustrates that the dynamic response of structures with non-linear dampers under the action of earthquake can be effectively and accurately analyzed by SIMULINK program. The dynamic analysis method by SIMULINK is the combination of structural control and modern control theory which may have wide application in structural control for its convenience, intuition and practicality.
