上海某在建带高位转换层超限高层结构,设计采用型钢混凝土框架-钢筋混凝土核心筒结构体系,结构地上共53层,高度250m。由于其高度超限,且同时存在加强层及超高位转换层,属于B级复杂高层建筑,需对其进行地震模拟振动台试验和精细的结构分析。采用通用有限元程序对缩尺模型结构的抗震性能进行数值模拟分析。结果表明,该结构体系能够满足抗震设防要求,计算结果与试验测量值基本一致。
In Shanghai, a transition zone with a high level of overrun high-rise structure is designed with a steel reinforced concrete frame-reinforced concrete core tube structure system, with a total of 53 floors and a height of 250m. Because of its height beyond the limit, and at the same time there is a reinforcement layer and ultra-high conversion layer, belonging to the B-level complex of high-rise buildings, the need to simulate the shaking table test and fine structure analysis. The common finite element program is used to simulate the seismic performance of scale model structure. The results show that the structural system can meet the seismic fortification requirements, and the calculated results are in good agreement with the experimental measurements.
