摘要
重庆袁家岗体育场为重庆市重点工程,建筑造型新颖、美观,下部看台为钢筋混凝土结构,屋盖为网壳钢结构,建成后为目前亚洲最大跨度的钢网壳结构。网壳外形呈西瓜皮状,钢材为Q345B圆钢管,节点以焊接空心球为主,少量采用铸钢空心球及相贯节点。铸钢件采用德国DIN1782标准中的GS20Mn5制作。通过风洞试验确定屋盖风载体型系数及风振系数。
The Yuanjiagang stadium is a major project in Chongqing city. The whole shape of architecture is very fancy and beautiful. The bottom of the stadium is made of concrete structure, and the top of it is made of steel mesh shell. The span of stadium is the longest of Asian steel shell structures. The shell is like the skin of watermelon, and its material is Q345B steel pipe. Most of the node are jointed with hollow ball node, and a few are made of cast steel and jointed directly. All cast steel member are made by Germany standard-DIN1782 GS20Mn5. According to the tunnel test, the wind coefficient （μs,β） of type and vibration are detemined, and the basic wind loads and its effects are calculated.
