南京金融城二期塔楼模型振动台试验设计

Design of shaking table test on the second phase tower of Nanjing Financial City

对一幢框架-核心筒超高层结构进行了整体模型振动台试验设计。试验设计是振动台试验中关键的基本问题,涉及材料、构件、节点构造、结构布置、荷载布置、模型简化,处理不当会造成试验结果的不准确。文章针对超高层小比例振动台试验,介绍了模型材料选取及配合比调整、相似关系设计、模型简化设计及试验方案设计;通过计算分析验证了简化方法的可行性;解决了小比例模型设计及施工遇到的难题,为今后类似超高层振动台试验设计提供借鉴。

Shaking table test design of a super high-rise structure is carried out.Test design is the key problem in the shaking table test,involving materials,components,joint structure,structural a rrangement,load arrangement,model simplification,the improper handling will cause inaccurate test results.The model material selection and mix proportion adjustment,similarity relationship design,model simplification design and test scheme design are introduced for small-scale shaking table test of super high-rise building.The feasibility of the simplified method is verified by calculation and analysis,the problem of small scale model design and construction is solved.The article will provide reference for similar super high-rise shaking table test design in the future.
