隔震技术在宿舍楼加固工程中的应用

摘要

Combined with the Jiangsu area last century built dormitory building engineering, by the comparison and analysis of frame structure of common reinforcement method, selected frame structure on the isolation technology based reinforcement scheme. Secondly, using the analysis software for the seismic performance analysis of the dormitory after reinforcement, the results show that the original structure was repaired after prolonged period of vibration isolation technology, acceleration of superstructure earthquake, interlayer displacement and interlaminar shear were obviously decreased, showed that the strengthened structure has a good seismic performance.%结合江苏地区某20世纪末兴建的宿舍楼工程,通过框架结构常见加固方法的对比分析,选定以隔震技术为主的框架结构加固方案.运用分析软件对加固后的宿舍楼进行抗震性能分析.结果表明,采用隔震技术对原结构进行修缮加固后结构自振周期延长,地震作用时上部结构加速度、层间位移及层间剪力均明显降低,加固后结构抗震性能良好.
