摘要
推导了脉动风荷载作用下考虑土 -结构相互作用时高层建筑结构加速度响应的计算公式 .算例表明土 -结构相互作用对高层建筑风振加速度响应有明显影响 .一般而言 ,在软土地基上土 -结构相互作用使高层建筑风振时加速度增加 ,从而增加了人体的不舒适感 ,甚至有可能影响到高层建筑的使用功能 。
Considering soil-structure interaction (SSI), the formula of acceleration response is derived for high rise building subjected to fluctuating wind load. Numerical examples show that SSI has evident effect on the acceleration response of the building. Generally speaking, SSI may increase the acceleration response of tall building constructed on soft soil ground, accordingly strengthen human discomfort in the building, or even affect its service function. So it should be paid more attention to the effect of SSI in the design of tall building.
