［摘要］成都來福士廣場T4塔樓豎向布置不規(guī)則，自下而上存在幾處收進(jìn)，且存在豎向構(gòu)件不連續(xù)、扭轉(zhuǎn)不規(guī)則等超限情況。為驗(yàn)證工程設(shè)計(jì)所采用的計(jì)算方法與構(gòu)造措施是否合理和滿足抗震要求，按照相似比關(guān)系制作了1∶20的模型，并進(jìn)行了模擬地震振動(dòng)臺試驗(yàn)。根據(jù)試驗(yàn)結(jié)果，檢驗(yàn)了結(jié)構(gòu)的抗震性能，研究并發(fā)現(xiàn)了結(jié)構(gòu)中的薄弱部位，提出了收進(jìn)位置節(jié)點(diǎn)加強(qiáng)等改進(jìn)措施。［關(guān)鍵詞］成都來福士廣場; 立面收進(jìn); 振動(dòng)臺試驗(yàn); 抗震性能中圖分類號：TU398.7 文獻(xiàn)標(biāo)識碼：A 文章編號：1002-848X(2015)13-0039-04
Shaking table test on T4 tower of Raffles City in ChengduTian Chunyu, Liu Junjin, Zhang Hong, Cao Jinzhe(China Academy of Building Research, Beijing 100013, China)Abstract: The T4 tower of Raffles City in Chengdu has irregular vertical arrangement with several setbacks from ground to top floor, and the structure also have out-of-code condition of discontinuous vertical components and irregular torsion. To verify that if the calculation method and structure details were reasonable and satisfied with the requirements of seismic design, shaking table test was carried out on the 1∶20 model which was produced according to the similarity ratio relationship. According to the test results, the seismic performance of the structure was tested, the weak parts of the structure were studied and found out, and measures of node strengthening of the setback position were put forward.Keywords:Raffles City in Chengdu; elevation setback; shaking table test; seismic performance
