| 摘 要： | 基于地震动随机场理论，给出了刚性平面基础六个运动分量的功率谱矩阵。矩形基础的研究结果表明，基础的刚性作用和地震动空间变化使基础的运动小于对应的自由场运动，尤其是高频地震动成分。给出的刚性基础地震动随机械型可用于建筑结构在多分量地震动作用的响应分析。

| Abstract: | The spectral matrix of flat rigid foundation,based on random field of seismic surfaceground motions, is derived. The results from rectangular foundation show that the input motionsat the bottom of structure are reduced due to the rigidity of foundation and the spatial variation ofearthquake motions,especially for the higher frequency motion. The model probabilisticsuggested may be used to investigate the effects of rotational motions and spatial variation ofseismic motions on the response of structures. |
