摘要
本文探讨了钢筋混凝土多层及高层建筑物与地基土共同作用体系的动力特性和主要影响参数,并且得到了体系基本周期和阻尼比的近似计算公式。利用快速富里叶变换(FFT),本文计算了体系的地震响应,探讨了共同作用对结构响应的影响。最后提出了一个结构响应的近似计算方法。
In this paper, the dynamic behaviour of the reinforced concrete multi-story building-foundation system, and the most important parameters have been studied. Approximate formulae for determining the foundamental period and the corresponding damping coefficient of the system have been obtained.The response of the system under seismic exitation has been calculated by using the FFT Method and the effects of soil-structure interaction on the dynamic response of the structure is discussed. Finally an approximate method for calculating the structural response is proposed.
