广州珠江新城西塔振动台试验研究

Shaking table test of Guangzhou Zhujiang West Tower model

广州珠江新城西塔工程为超高层建筑结构,进行了模拟地震振动台试验。为了使得振动台试验获得良好效果,在该工程结构振动台试验的模型设计阶段进行了模型结构简化、相似比设计、模型结构构件设计和模型节点构造设计。对模型构件和节点进行试验研究,结果表明模型构件和节点与原型结构构件和节点的刚度、承载力相似关系均符合要求,保证模型与原型的弹性相似和破坏形态的相似,保证了振动台试验结果的准确性,并为类似工程的振动台试验工作提供了良好的基础和借鉴。

Shaking table test was conducted on a high-rise building,West Tower in Guangzhou Zhujiang New City.Some issues regarding shaking test model design were discussed,including structure simplification,model member design,and model joint design.Tests on model members and joints show that the rigidity and capacity of test models are similar to the original structure,which guarantees the accuracy of the shaking table test.
