摘要: 近代優(yōu)秀建筑出于保護(hù)的要求,結(jié)構(gòu)加固方法受到諸多制約,隨著時(shí)間流逝,材料強(qiáng)度等也逐漸劣化,隨著科技水平的不斷發(fā)展,結(jié)構(gòu)構(gòu)造要求也不斷提高,因此此類建筑往往不能滿足現(xiàn)有的抗震設(shè)防要求. 結(jié)合某優(yōu)秀歷史建筑修繕加固項(xiàng)目,介紹了采用壁式黏彈性阻尼器加固的設(shè)計(jì)方法,極大地減少了對(duì)主體結(jié)構(gòu)的干預(yù);基于底部剪力法提出了對(duì)阻尼器參數(shù)進(jìn)行優(yōu)化的簡(jiǎn)化方法,根據(jù)不同地震水準(zhǔn)下結(jié)構(gòu)變形控制目標(biāo),可較為便捷地確定阻尼器型號(hào),并通過(guò)時(shí)程分析法對(duì)結(jié)構(gòu)的抗震性能進(jìn)行了驗(yàn)證. 分析結(jié)果表明:壁式黏彈性阻尼器有效提高了主體結(jié)構(gòu)的剛度和附加阻尼,提高了結(jié)構(gòu)的整體抗震性能. 該方法布置靈活,對(duì)建筑本體干預(yù)小、過(guò)程可逆,可作為近代建筑抗震加固的有效方式之一.

Abstract: Due to the protection requirements of historical excellent buildings, the structural reinforcement methods aresubject to many constraints. As time goes by, the strength of materials gradually deteriorate, and the requirement ofconstruction details becoming more and more strong with the continuous development of science and technology, thehistorical building usually cannot meet the current structural seismic fortification. Based on the renovation and reinforcementproject of an excellent historical building, the design method of wall-type total response control damper reinforcement wasintroduced, which greatly reduces the intervention on the main structure; based on the bottom shear method, a simplifiedmethod for optimizing the damper parameters was proposed. According to the structural deformation control objectives underdifferent earthquake levels, the type of damper can be determined more conveniently, and the seismic performance of thestructure was verified by time-history analysis. The analysis results show that the wall-type total response control dampercan effectively improve the stiffness and additional damping of the main structure, and improve the overall seismicperformance of the structure. The method has flexible layout, little intervention on the building itself, and the process isreversible, which can be used as one of the effective methods for seismic reinforcement of modern buildings.
