贵阳市某钢结构雕塑的结构体系分析及其静荷载试验研究

Structural system's analysis and static load test of a steel structure sculpture located at city of Guiyang

针对贵阳市某钢结构雕塑静荷载试验,分析了结构的受力特点,总结了采用肋环型正交管桁架结构的优势,并根据工程实际情况,确定了试验加载范围、观测点及具体静荷载试验方案,讨论了试验误差产生的原因。结果表明:采用局部加载方案能够反映原设计活荷载作用效应,在正常使用情况下该结构仍处于弹性工作阶段。

Based on static load test of a steel structure sculpture located at city of Guiyang, structural mechanical features are analysed and the advantages of Geiger orthogonal tube truss is summarized. According to practical situation of the project, test loading range, observation points and testing scheme are determined. The causes of test error are discussed. The results show that local loading scheme can reflect the effect of design live load. The structure is still in elastic stage under the normal situation.
