摘要
本文提出了基于SIMULINK和STATEFLOW的双线性隔震体系仿真分析方法,分析了双线性隔震体系反应对体系参数的敏感性,给出了双线性隔震体系反应与其基本参数的关系谱图。研究表明:屈服系数和第二隔震周期是影响双线性隔震体系反应的主因子,而第一隔震周期对体系反应的影响相对较小;隔震体系最优屈服系数与输入地震动水平相关;隔震体系反应与其基本参数的关系谱图呈现出明显的非线性特征,基本参数在较高水平存在较大的交互作用。
A seismic simulation method for the bilinear system of base isolation building based on SIMULINK and STATEFLOW was proposed. The system response sensitivities to its basic parameters were analyzed. The relation spectra between system responses and system basic parameters were established. Research indicated that the dominated factors to system seismic response are the yield coefficient and the second period of the b/linear system, while the first period of the system is subordinative. The optimal yield coefficient of the system is correlative with earthquake level. The relation spectra present notably nonlinear. The system basic parameters have significant interaction in higher level.
