摘要(Abstract):

郑州新郑国际机场改扩建工程采用了斜撑-上挠曲线拉索-双变截面箱形曲梁组合结构,屋盖为四跨波浪式轻钢屋面。采用合理的结构形式提高了结构抗风变形的能力以及减小竖向荷载作用下结构的外张变形。对结构在各种荷载工况下的内力进行了分析,结果表明,结构受力合理。对曲梁的形式和索力大小之间的关系进行了分析,得到了合理的索张拉力取值。
The combination structure of diagonal bracing,up-deformation curve cable and bi-variational box section beam is adopted in Xinzheng International Airport rebuilt and retrofitting.The light steel roof with four-span conk shape is used.The rational structural system improves the anti-deformation of structure under wind load and vertical load.The internal forces under all load combination are analyzed,and the results show that the bearing characteristic of the structure is reasonable.Based on the analysis of relation between shape of curve beam and forces of cables,the rational tension forces(are got. )
