【摘要】 在竖向串联多自由度模型基础上，建立了采用不同方法（线性加速度法、Ｗｉｌｓｏｎ－θ法、Ｎｅｗｍａｒｋ－β法）求解建筑结构非线性动力响应的统一算式“拟动力方程”，列出了计算步骤．该法物理概念明确，计算步骤清晰．同时可克服计算中的积累误差问题更多还原

【Abstract】 Based on multi degree of freedom (MDOF) of structural system,the unified formula “imitative dynamic equation” applied different methods (linear acceleration,Wilson θ ,Newmark β ) is set up to calculate non linear dynamic responses of structure,and their calculation steps are given.The methods are clear in physical idea and calculation steps,and overcoming accumulative error in calculation.更多还原
