摘要
对天津高银117大厦巨型支撑框架-核心筒结构模型进行了整体模型振动台试验,研究了结构在7.5度小震到8度大震下的地震响应,分析了结构自振特性、动力系数、位移以及损伤的发展规律。结果表明:结构设计合理,能满足规范及抗震设计性能目标的要求。在试验研究基础上,对结构设计提出了改进建议,以进一步提高结构的抗震安全性。
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.
