［摘要］连云港体育场看台顶篷为斜拉网壳结构体系，建筑造型新颖独特，对结构选型和布置提出了较高要求。文中分析了几何拉索非线性对结构的影响，考虑各种荷载工况，对结构进行了全面的分析。分析结果表明，此类结构体系的非线性效应显著，异形顶篷屋面对风荷载非常敏感，应保证拉索在风压和风吸状态下均处于工作状态。

Abstract:Due to the unique roof architectural style of Lianyungang Stadium, the structrue selection and arrangement are difficult. The effect of large deformation on the lattice shell structure was analyzed and various load cases were taken into account. Analytical results indicate that the large deformation should be considered in this kind of structural system. This special steel roof is sensitive to wind loads and  the cables should be ensured to work in any wind load case.

Keywords:lattice shell structure; force-bearing properties; load case; large-span steel structure; nonlinearity
