【摘要】 提出了一种计算多点输入下结构最大地震内力的新反应谱法(MRSM-AD)。不同于以往的多点输入反应谱法,这种方法不再将结构的绝对位移反应分解成拟静力和动力分量,而是直接利用基于结构绝对位移反应的动力方程进行反应谱理论的分析,简化了多点输入反应谱法中的组合规则,提高了结构计算分析的效率。比较了结构算例的时程法计算结果和MRSM-AD法的分析结果,验证了MRSM-AD法的正确性。更多还原

【Abstract】 A response spectrum method was proposed for the seismic analysis of structural seismic force responses to multi-support excitations. Instead of partitioning the total structural response into the pseudo-static and dynamic components, the absolute displacement formulation was directly utilized in the method and thus the response spectrum combination rule was simplified for multi-support excitations. The seismic response of a structural example was studied, whereby a good agreement between the results of the time history method and the proposed method showed the validity of the latter method.更多还原
