| 摘 要： | 复杂场地的土层地震反应分析对结构的地震反应计算及抗震安全性评价有重要意义。采用直接有限元法对土层进行三维建模,可使系统的计算力学模型更加符合实际情况。但由此带来的计算量之大,使得传统的计算方法难以胜任。在此背景下,本文利用静力子结构方法推导了在多点输入模式下进行土层地震反应分析时拟静力位移的求解步骤,并通过均匀土层算例验证了行波输入下利用约束子结构模态综合法进行复杂场地地震反应分析的可行性。

| Abstract: | The seismic response analysis of irregular topography is important for calculation of the seismic responses of structures and the safety valuation of earthquake resistant buildings.Direct finite element based method is ideal for simulating the actual soil situations.However,the calculating workload largely is so large that traditional algorithm is unsuitable.Therefore,we propose a static substructure analysis method to compute the pseudo-static displacements of the seismic response of soil.The results from ... |
