摘要
本文采用耗能减震技术,根据建筑结构抗震规范规定的反应谱法,利用CTAB程序对云南省洱源县振戎中学食堂进行了抗震计算分析和设计验算.首先对未加耗能减震装置的空框架结构进行了小震下的位移和强度验算以及大震下的位移验算;其次,介绍了本工程选用的T字芯板摩擦耗能器的工作原理,并对耗能器进行了足尺性能试验;第三,根据工程结构的环境特点和建筑使用功能要求,确定了耗能减震方案;最后,对耗能减震结构进行了抗震验算和分析,结果表明,附加耗能器后的工程结构抗震性能得到了明显改善.
In this paper, based on response spectra method regulated in building seismic code, a dinging-room structure of Zhenrong middle school,Yunan province, with energy dissipators is analyzed and designed under earthquake. First of all, CTAB program is used to check the strength and deformation of the original structure. Then, working mechanism of T-core friction energy dissipators is introduced and property test of the full-scale dissipator is carried out. Finally, the location of energy dissipators in structure is determined based on the building function, and the corresponding energy dissipation system is analyzed an4 designed under earthquake. The analysis results show that the seismic capacity of structure is improved by using the energy dissipators.
