【摘要】 本文用理论和实例计算分析了土与结构间的动力相互作用。根据基底等效输入的地震动相对入射地震动的传递函数特点研究出了一种等效输入的方法,该方法比较好地反映了场地和结构的动力特性对基底等效输入的影响。为利用刚性基底假设理论来分析土-结构动力相互作用提供了一种方法。更多还原

【Abstract】 In this paper, the soil structure dynamic interaction is analyzed by theory and example calculation. The characteristics of transfer function of equivalent input ground motion on ground relative to incident ground motion on bedrock are studied. Then the method for determining equivalent input is put forward by characters of this transfer function. This method well reflects the characteristics of site and structure. A kind of method to analyze the soil structure interaction is put forward based on the assumption of rigid foundation.更多还原
