一座空旷砖混厂房结构的隔震加固

Application of base isolation to reinforcement for a single-story spacious building

介绍一栋砖混单层厂房的隔震加固方案,对加固后结构与原结构的地震反应作了对比分析,分析结果表明隔震加固大大提高了原结构的抗震性能。对加固所用的隔震支座性能作了具体分析,提供了支座的设计与试验对比结果,并对砌体结构隔震加固中采用的"夹梁托墙"技术的可行性作了试验研究,结果表明:支座的设计分析结果与试验结果吻合较好,夹梁具有良好的工作性能。

This paper introduces the design details and calculation results of a single-story spacious building reinforced by base isolation. The results obtained from the test and calculation which include the earthquake responses,of the original and reinforced building, as well as features of the low stiffness rubber bearings are compared. In the end, the efficiency of the brick wall reinforcement is certified by the test of the interaction between brick wall and the new concrete beams that is adopted in the building reinforcement. All above indicate that base isolation is an effective method used in structural reinforcement.
