摘要
埋置基础输入运动的求解是采用子结构法进行土与结构相互作用的关键问题之一。目前的求解方法十分繁杂。本文提出一种近似解析公式,可以简便地求出各种波入射情况下的基础输入运动。
A simplified technique to obtain foundation input motions for circular cylindrical foundations embedded in the ground and subjected to seismic motion is presented. The major advantage of this approach is its simplicity, with which the parameters can be changed. This approach requires only the impedance functions of the circular disc.
