| 摘 要： | 考虑地震的随机性和土体的非线性,引入粘弹性边界,提出了一种在谐响应分析中直接输入加速度的加载方式,建立了基于虚拟激励法、等效线性化法和确定性动力有限元法相结合的非线性桩-土-结构体系随机地震响应的实用计算方法.采用该法对单桩支承的剪切型结构进行了较为全面的参数分析.结果表明基岩地震动输入水平,桩长度和土体模量都对结构反应有较大影响.该方法可方便的用于随机地震下桩-土-结构体系的参数分析中.

| Abstract: | Considering the randomness of earthquake and the nonlinearity of soil,introducing viscous-spring boundary,a loading pattern of inputting acceleration directly in harmonic response analysis is proposed.The practical calculation method of stochastic vibration response for pile-soi-structure interaction system based on pseudo-excitation method,equivalent linearization method and definite dynamic finite element method is presented.The parametric analyses of the single end-bearing pile structure are conducted in... |
