利用非线性时程分析法研究了地震工程学中常用的三种等效线性化方法对非线性减震耗能系统的实用性。对等效线性化处理过的模型 ,采用振型分解反应谱法计算 ,与非线性时程分析结果相比 ,虽存在结构层间最大剪力 Vmax较符而耗能元件最大变形 Xmax较差 ,或 Vmax较差而 Xmax却较符的问题 ,但从 Vmax和 Xm ax两方面看 ,均存在一定的可比性。分析认为 ,对非线性减震耗能系统等效线性化处理后 ,再采用振型分解反应谱方法计算 ,是较为可行的抗震分析方法。在采用等效线性化方法时 ,需结合等效的物理量来考虑 The nonlinear time-history analysis method is used to study the practicability of the three equivalent linearization methods commonly used in seismic engineering for the nonlinear damping energy dissipation system. Compared with the nonlinear time-history analysis, the equivalent linearized model is modeled by the modal decomposition reaction spectrum method, although the maximum shear Vmax of the structural layer is better than the maximum deformation of the energy dissipating element Xmax, Or Vmax is worse and Xmax is better, but there are certain comparability in terms of both Vmax and Xm ax. The analysis shows that it is a feasible method for seismic analysis after equivalent linearization of nonlinear damping energy dissipation system and then using mode decomposition decomposition spectrum method. When using the equivalent linearization method, we must consider the equivalent physical quantity
