| 摘 要： | 本文在考虑土体-结构相互作用的基础上，结合实际工程，对地震作用下的消能减震结构体系进行了对比分析。分析表明，考虑土体-结构相互作用，对于消能减震结构体系的动力特性具有明显的影响。详细考察消能框架体系的楼层位移、楼层速度、楼层加速度以及楼层剪力等指标，在考虑土体-结构相互作用后，减震效果均明显变差；而且上述各指标在各楼层之间减震效果的差异也会增大。

| Abstract: | The seismic responses of energy dissipating structure considering soil-structure-interaction are studied through a real project of energy dissipating structure.It is found that the soil-structure interaction has great influence on the behavior of energy dissipating structure.The reduction effect of the energy dissipating structure's floor displacement,floor velocity,floor acceleration and floor shear force would be mitigated.And their discrepancies between the floors would arise. |
