| 摘 要： | 同济大学土木工程防灾国家重点实验室对上海环球金融中心大厦进行了整体结构模型的振动台试验.该大厦101层,结构高度492m,拟建成为世界上结构主体最高的建筑物.本文详细介绍了大厦结构体系、振动台试验模型材料的选取、动力相似关系的确定以及试验方案的设计.针对超高层整体结构小比例模型施工困难的特点,提出了模型的简化方法,并利用ANSYS对简化模型进行了计算,计算结果表明模型简化对结构自振特性和地震反应影响很小,验证了简化方法的可行性.本文提供的模型和试验的设计思路对今后有关的试验工作有一定的借鉴作用.

| Abstract: | A shaking table model test was carried out for Shanghai World Financial Center to study its seismic behavior in State Key Laboratory for Disaster Reduction in Civil Engineering at Tongji University. The height of 101storey Shanghai World Financial Center is 492m above ground, making it possible to be the tallest building in the world when completed. The paper illustrates the structural system characteristics in detail, model material selection, similitude-scaling relationship and design of test program. Due to the difficulties in fabrication of the scaled model of super-tall building, a simplified method is proposed. ANSYS is used to analyze the simplified model and the results demonstrate that the dynamic characteristics and seismic responses of simplified model are approximate to those of prototype structure. The conclusion is that the proposed method is feasible in the test. The method applied in model and test program design of this super-tall building will be helpful to other experimental studies. |
