凤凰古城旅游服务中心结构设计

The Structural Design of Fenghuang Ancient Town Tourism Service Center

凤凰古城旅游服务中心为造型复杂的钢桁架结构,桁架跨度31.2 m,端部悬挑10 m。文章对结构桁架选型进行了对比,对构件截面选择进行了分析,通过柱截面增设加劲板、采用变截面弦杆来优化结构,并对变截面弦杆连接提出了采用内坡口的施工要求,相应做法可供类似项目参考。

Fenghuang Ancient Town Tourism Service Center is a complex steel truss structure with a span of 31.2 m and a cantilevered end of 10 m.The selection of structural truss is compared,and the selection of component section is analyzed.The structure is optimized by adding stiffening plate to column section and using variable cross-section chord members.The construction requirements of using inner groove are put forward for variable cross-section chord member connection,which can be used as a reference for similar projects.
