| 摘 要： | 为研究地下室埋深对高层建筑地震反应的影响,以实际工程中的某高层剪力墙结构为研究对象,采用理论分析和三维数值模拟相结合的方法,研究了地下室埋深和地基支撑刚度对高层钢筋混凝土结构抗震性能的影响。结果表明:随着地下室埋深的增加,结构的周期有变大的趋势;同时结构承受的地震作用将减少,使得结构抗震性能有较明显的提高;地基对结构支撑作用的变化对结构抗震性能的影响不大。

| Abstract: | In order to study the effect of basement depth on the seismic response of high rise buildings,a high-rise shear wall structure was studied.The influence of basement depth and foundation stiffness on the seismic performance of the high-rise reinforced concrete structure was analyzed by a combination of theoritical analysis and 3D numerical simulation.The results show that with the increase of basement depth,the structural period will increase and the earthquake action on structures will be reduced,improving the seismic performance of the structure obviously.The change of foundation support has little effect on the seismic performance of the structure. |

| Keywords: | high-rise buildings basement depth seismic response foundation stiffness |
