【摘要】 本文根据子结构法思想提出了相互作用体系在频域内的运动方程,同时应用波在连续介质中的传播理论和间接边界元法推导了格林影响函数,从而进一步推导了地基土的动力刚度系数。文中通过计算带埋置的刚性矩形基础的平面剪切型结构的地震动力响应,并与基底固定的计算结果作比较,得到了有意义的结论。更多还原

【Abstract】 Based on the substructure approach,the motion equations of interaction system in frequency domain are given in this paper. In the formation of the Green’s functions and the dynamic-stiffness coefficients,the concepts of wave propagation in a continuum and the indirect bouudary-ele ment method are used. For plane shear structure with rigid rectangular foundation embedded,its seismic response are calculated. The results are compared with that of the fixed base. Thus,some useful results are obtained.更多还原
