摘 要: | 为研究混合结构的整体抗震性能,本研究以一个Ⅷ度区的LG大厦为原型,制作了1/20的整体模型,在同济大学土木工程国家重点实验室进行振动台试验,以考察地震动频谱及地震强度对混合结构地震反应的影响,了解混合结构体系的抗震性能、地震反应和破坏特征.本文还利用纤维模型建模对混合结构整体抗震性进行了非线性分析计算,并将计算结果与振动台试验数据进行对比分析,试验和计算结果表明:外钢骨框架-内混凝土核心筒混合结构具有较好的抗震性能.

Shaking table model test and theoretical analysis for seismic resistance of hybrid structures |
| |
Abstract: | A shaking table test has been taken for a 1/20 model based on LG tower in State Key Laboratory for Disaster Reduction in Civil Engineering of Tongji University, for studying seismic resistance of hybrid structures. In this test, the influence of earthquake spectrum and intensity on the performance of hybrid structures was investigated. Also, its earthquake-resistance, earthquake response and damage characteristics were studied. The data obtained from this test and the calculated data using fiber model were compared. Based on results of test and calculation,it is concluded that the exterior steel-encased reinforced concrete frame-interior RC tube structures have very good seismic resistant performance. |
