摘要:
提出了滑移隔震结构基本体系的概念,根据振型分解法将上部结构解耦为互相独立的单质点体系.如果隔震层质量合理分配到上述单质点体系,则结构有可能进一步解耦,形成与上部结构模态数目相同的隔震基本体系.上部结构的反应可由基本体系的相应反应通过振型叠加得到,隔震层的反应与任一基本体系的相应反应量相同.工程算例表明,该方法完全满足工程精度要求,对该类非线性系统进行降维解耦的思路具有较高的可行性.
Abstract:
Conception of elementary sliding base-isolated system(ESBS)is proposed. Using the method of modal analysis, superstructure is uncoupled into independent single DOF(degree of freedom)systems. If the mass of isolation layer is reasonably distributed to the systems, structure may be further uncoupled into ESBS with same amount of the superstructure modals. The superstructure responses can be obtained by superimposing corresponding responses of ESBS, and the isolation layer responses are identical with corresponding responses of any ESBS. The simulation analysis shows that the proposed method fully satisfies the requirement of engineering in precision, and the thought seems highly feasible in uncoupling this kind of nonlinear system.
