| 摘 要： | 讨论了几何偏心和非均匀地面激发对于基础埋置在弹性半空间中的单层结构的影响．地面激发为水平和竖向简谐剪切波．数值结果表明：剪切波对于建筑在软土地基中又有一定埋置深度的低矮建筑物有较大影响．设计中，以自由场地面运动记录取代建筑物基底运动记录会得到较大的整体动力响应值

| Abstract: | A one-story structure with rigid cylindrical foundation embedded into an elastic half space is used to examine the effects of combined geometric eccentricity and non uniform base excitation on soil structure. The excitation consists of horizontally or vertically incident harmonic SH waves. The numerical results indecate that squatty structure with embeded foundation and supported on soft soils are more strongly influenced by SH waves. If the motion record at the base of buildings is replaced with the free field surface motion, the dynamic responses of whole structure will be significantly larger. |
