| 摘 要： | 随着新版建筑抗震设计规范的出台,建筑物抗震设计要求也日益提高.在以往的高层建筑地震响应分析中,由于计算技术上的困难和经济上的约束,大多数时候工程师们都采用了固定基底假设.这样做对于建立在刚性比较大的地基上的结构,由于相互作用不是很明显,还是可以接受的,但是对于建立在软弱地基上的结构,由于相互作用比较强烈,在计算中是应该...

| Abstract: | As new code for seismic design of buildings is published,requirements of building seismic design are increasing too.In the past,because of difficulties in calculation and economic constraints,the assumption of fixed base is adopted in seismic analysis of high-rise buildings.For the structure built on rigid ground,the method is acceptable because the soil-structure interaction is not obvious.However,for the structure on soft ground,soil-sturcture interaction should be considered because the interaction is strong.In this paper,high-rise structure models of considering and not considering soil-structure interaction are established separately and necessity of considering soil-structure interaction is analyzed. |
