摘　　要：国家速滑馆是2022年北京冬奥会的标志性场馆,为北京市唯一新建的奥运场馆。介绍了国家速滑馆地上钢结构设计中的关键问题。国家速滑馆地上钢结构体系由马鞍形索网、巨型环桁架、斜拉索、幕墙网壳等体系组成。工程设计影响因素多,各部分体系关系复杂,设计时需考虑多因素的耦合效应,设计难度大。还介绍了国家速滑馆钢结构体系及支承条件,介绍了钢结构设计中的难点及解决方案,研究了施工各阶段钢结构体系的稳定性,研究了环桁架及其支承体系的防连续倒塌性能及预防措施,介绍了关键节点的设计方法。The National Speed Skating Oval（NSSO） will be an iconic building during the 2022 Beijing Winter Olympics, which will be the only new-built venue in Beijing. The key issues in the design of the above ground steel structure of the Nional Speed Skating Oval were introduced. The steel structural system of the NSSO consisted of several systems including saddle-shaped cable net, mega ring truss, stay cable and reticulated shell of the curtain wall. The design process took into account numerous factors. The relationship between each part of the system was complex. The coupling effect of multi-factors needed to be considered during design, and the design was difficult. The steel structural system and supporting conditions of the NSSO were introduced as well as the difficulties and solutions in the design of steel structure. The stability of the steel structural system at various stages of construction was studied, and performance and preventive measures for progressive collapse was studied on the ring truss and its supporting system. The design method of key nodes was introduced.
