摘要
本文对首都机场新塔台钢筋混凝土筒-钢框架组合结构缩尺模型进行了模拟地震振动台试验研究,分析了高耸塔台结构的地震反应和破坏特征,并对这种下部为混凝土筒体,上部为钢框架结构的锚固连接及钢框架结构层间位移控制进行了探讨,为提出这类钢-混凝土组合结构体系抗震计算模型和设计理论提供了试验依据。
Seismic tests were conducted for a model of typical reinforced concrete tube and steel frame composite structure of tall tower on shaking table. The dynamic properties, seismic responses and damage features of the model were recorded and analyzed .The behavior of the model subjected to earthquakes is discussed. The study provides a basis for the earthquake resistant design and analysis of this kind of structure.
