摘要
福建南安62m郑成功大型石雕塑像为我国少有的高层石雕像结构,其结构体系为高层异形型钢混凝土框架-核心筒组合结构。首先采用盈建科(YJK)和MidasGEN两种软件进行了小震弹性计算,同时采用风洞试验及YJK开展抗风性能分析。计算结果显示,结构的层间位移角、侧向刚度比等指标均满足规范要求。然后,采用SAUSGE软件进行动力弹塑性分析,确保结构可以实现大震不倒的性能目标。通过以上分析结果可知,此高层异形组合结构的工作性能均能满足规范要求,可供同类工程设计借鉴。
The 62 m Zheng Chenggong large stone statue in Nan’an, Fujian Province is a rare high-rise stone statue structure in China. Its structural system is high-rise steel reinforced concrete frame-tube structure with special shape.Firstly, the elastic calculation of small earthquakes is carried out by using YJK and Midas Building, and the wind tunnel test and YJK are used to analyze the wind resistance performance. The results show that the story drift and lateral stiffness ratio of the structure meet the requirements of the code. Then, the dynamic elasto-plastic analysis is carried out by using sausge software to ensure that the structure can achieve the performance goal of strong earthquake. According to the above analysis results, the working performance of this high-rise special-shaped composite structure can meet the requirements of the code, which can be used for reference for similar engineering design.
