［摘要］連云港體育場看臺頂篷為斜拉網(wǎng)殼結(jié)構(gòu)體系，建筑造型新穎獨(dú)特，對結(jié)構(gòu)選型和布置提出了較高要求。文中分析了幾何拉索非線性對結(jié)構(gòu)的影響，考慮各種荷載工況，對結(jié)構(gòu)進(jìn)行了全面的分析。分析結(jié)果表明，此類結(jié)構(gòu)體系的非線性效應(yīng)顯著，異形頂篷屋面對風(fēng)荷載非常敏感，應(yīng)保證拉索在風(fēng)壓和風(fēng)吸狀態(tài)下均處于工作狀態(tài)。

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
