摘要
丝路欢乐世界地标工程为丝路舞者造型,其顶部为莫比乌斯环,立面形体为自由曲面形态的裙摆及丝带。结构主体采用斜交网格筒体支承建筑造型,莫比乌斯环、裙摆及丝带造型采用桁架实现。主要介绍该工程的结构设计思路,采用PKPM和SAP2000两种软件对结构进行了多遇地震作用下的整体计算,并采用弹性时程分析法进行补充验算;由于结构存在多项不规则项,因而采用性能化设计方法保证关键构件在设防地震和罕遇地震作用下达到性能目标,并采用动力弹塑性时程分析法进行补充验算;对结构进行整体屈曲稳定性分析,并采用直接分析法研究构件稳定性;此外,考虑温度作用对结构进行专项分析,并对关键节点补充有限元分析计算。分析结果表明,结构布置合理、安全可靠。
The Silk Road Paradise Landmark project is shaped like a Silk Road dancer.Its top is Mobius strip,and the facade is shaped by free-form skirt and ribbon.The main body of the structure adopts the diagrid tube system to support the architectural modeling.The design of Mobius strip,skirt and ribbon are realized through trusses.The structural design idea of the project was mainly introduced.Programs of PKPM and SAP2000 were used to analyze the overall structure under frequent earthquakes,and the elastic time-history analysis method was used for supplementary analysis.Due to the existence of a number of irregular items in the structure,the performance-based design method was used to ensure that the key components achieve the performance target under the action of fortification earthquake and rare earthquake,and the dynamic elastic-plastic time-history analysis method was used for supplementary checking.The overall buckling stability of the structure was analyzed,and the stability of the component was studied by direct analysis method.In addition,a special analysis of the structure was carried out considering the temperature effect,and the finite element analysis was applied to analyze key nodes.The analysis results show that the structure layout is reasonable,safe and reliable.
