摘　　要：雄安城市计算中心屋盖为覆土重载屋面.地上为钢框架结构,屋盖采用部分落地斜交网格双层网壳结构.屋盖网壳南北两侧支承于9m间距框架柱上,西侧收缩与斜放Y形柱交汇后落地,东侧支承于立体拱桁架上,中部由12根钢管混凝土柱支承,网壳最大跨度105m,厚度2.5m.本文介绍了屋盖钢结构网壳的设计和优化过程,包括设计方案演变、基于图乘法的构件截面优化和考虑施工便利性的构件节点设计及施工过程.优化后屋盖结构体系安全可靠,施工便利,可供类似项目参考.The roof of the Xiongan Urban Computing Center is a heavy roof with soil on it.It is a steel frame structure with a double-layered steel shell structure with a partially landed inclined intersection grid.In this paper,the design and optimization process of the steel roof is presented,including the evolution of the design scheme,the optimization of sections based on the graph multiplication method and the design of member nodes considering the construction convenience.The optimized roof structure system is safe,reliable and convenient to construct,which can be used as a reference for similar projects.
