本文根据能量相等的近似方法,研究了置于弹性半空间表面并受斜入射平面SH波作用的刚性圆形和环形基础的扭转反应。本文方法所得结果与某些近似解和精确解的结果对比,表明本文方法对抗震设计是有效的。
In this paper, the torsional response of rigid circular and annular foundations subjected to SH waves at the oblique incidence plane is investigated on the basis of an energy equal approximation method. The results obtained by this method are compared with the results of some approximate solutions and exact solutions, which shows that the proposed method is effective for seismic design.
