摘要
依据建筑物的抗震设计的基本目标,考虑地震加速反应谱作用地基土体与结构,应用极限强度法,验证结构安全性能,研究结构固有周期和地基土体耦合系统动、静态在水平方向与旋转阻尼特性,为评价地基与建筑物耦合系统的固有周期与阻尼具有重要意义。
In accordance with the basic purpose of building design against earthquake and the action of seismic accelerating response spectrum in foundation soil and building, limit strength method was used to verify the structural safety performance and research the natural period of structure and rotational damping characteristics of the dynamic and static foundation and soil coupling system in horizontal direction. It is of great significant to evaluate natural period and damping of foundation and structural coupling system.
