援科特迪瓦体育场结构设计及施工配合要点分析

Analysis on structural design and construction cooperation of C?te d’Ivoire Stadium

针对援科特迪瓦共和国阿比让体育场看台结构超长、场地地势土层不均、异形混凝土结构造型复杂、施工难度大等特点,采取相应的结构措施解决设计和施工中的问题。桩基础根据地形采用不同桩长,满足承载力和变形要求;对超长的混凝土看台采取相应构造和施工措施避免开裂;对于外围异形框架体系采用有限元软件分析分缝处应力情况,确保不出现应力突变;结合施工可行性优化节点钢筋排布和预埋件形式,保证结构安全的同时,也实现了建筑功能和艺术形态。同时也对混凝土看台设计要点,钢结构罩棚设计要点及钢结构罩棚的施工安装模拟进行了介绍。

The super-long structure of the Abidjan Stadium in the Republic of Cte d’Ivoire,the terrain of the site is uneven,the shape of the special-shaped concrete structure is complex,and the construction is difficult.The corresponding structural measures were taken to solve the problems in design and construction.The pile foundation adopted different pile lengths according to the terrain to meet the bearing capacity and deformation requirements;corresponding structures and construction measures were taken to avoid cracking for the super-long concrete stands;for the peripheral special-shaped frame system,the finite element software was used to analyze the stress at the joints to ensure that no sudden change of stress occurred;combined with the construction feasibility,the joint reinforced arrangement was optimized and the embedded parts were optimized to ensure the structural safety,and also realize the architectural function and artistic form.At the same time,the design points of the concrete stand,the design points of the steel structure shed and the construction and installation simulation of the steel structure shed were also introduced.
