［摘要］對(duì)天津高銀117大廈巨型支撐框架-核心筒結(jié)構(gòu)模型進(jìn)行了整體模型振動(dòng)臺(tái)試驗(yàn)，研究了結(jié)構(gòu)在7.5度小震到8度大震下的地震響應(yīng)，分析了結(jié)構(gòu)自振特性、動(dòng)力系數(shù)、位移以及損傷的發(fā)展規(guī)律。結(jié)果表明：結(jié)構(gòu)設(shè)計(jì)合理，能滿足規(guī)范及抗震設(shè)計(jì)性能目標(biāo)的要求。在試驗(yàn)研究基礎(chǔ)上，對(duì)結(jié)構(gòu)設(shè)計(jì)提出了改進(jìn)建議，以進(jìn)一步提高結(jié)構(gòu)的抗震安全性。［關(guān)鍵詞］天津高銀117大廈; 超高層建筑; 振動(dòng)臺(tái)試驗(yàn); 巨型支撐框架; 抗震設(shè)計(jì)中圖分類(lèi)號(hào)：TU973.3+l，TU317+.1，P315.9 文獻(xiàn)標(biāo)識(shí)碼：A 文章編號(hào)：1002-848X(2015)22-0001-06
Shaking table test research on model of mega braced frame-core wall structure for Tianjin Goldin 117 TowerZhang Hong, Tian Chunyu, Xiao Congzhen, Cao Jinzhe, Hao Wei, Li Jianhui（China Academy of Building Research, Beijing 100013, China）Abstract: Shaking table test on model of mega braced frame-core wall structure for Tianjin Goldin 117 Tower was carried out. The earthquake responses of the model was studied under various seismic actions from 7.5 degree frequent earthquake to 8 degree rare earthquake. The development rule of vibration characteristics, dynamic coefficient, displacement and damage was analyzed. The results show that the structure is designed reasonably, and can satisfy the requirements of codes and achieve the target of performance-based seismic design. Based on the shaking table test, some improvement suggestions about the structure design were proposed, and the safety of the structure was further improved.Keywords: Tianjin Goldin 117 Tower; super-tall building; shaking table test; mega braced frame; seismic design
