[提要]  对启东市长江新村12号砌体结构住宅楼进行了基础隔震设计，采用时程分析法对隔震结构的地震反应进行了计算。计算结果表明，隔震结构在大震作用下仍处于弹性工作状态，结构由传统抗震设计的“大震不倒”提高到“大震不坏”，具有优越的抗震性能。

Systemic isolation design of a brick masonry residence building in Qidong is processed. The aseismic behavior of the isolated building under earthquakes is studied with time history analysis method. The calculation results show that the isolated building keeps elastic state under seldonly occured earthquakes and has excellent aseismic behavior.
