沈阳桃仙国际机场扩建工程航站楼为钢 -预应力混凝土组合框排架结构。最大整体楼面平面面积 2 6 0m×87m ,不设温度变形缝 ,最大柱网尺寸 2 4m× 1 8m。由于设计中有效的解决了大跨度、变跨度、变截面、变支承条件连续框排架梁的截面和配筋调整 ,梁和板的抗裂构造处理 ,两种结构体系组合节点设计等技术关键问题 ,使该建筑成为整体超大平面大跨度楼面设计的典型工程 ,为国内类似规模建筑的楼面设计提供了成功经验。
Shenyang Taoxian International Airport expansion project terminal building for the steel - prestressed concrete box frame structure. The largest overall floor area of 2 6 0m × 87m, without temperature deformation joints, the maximum column size 24m × 18m. Due to the effective solution to the design of large span, variable span, variable cross-section, variable support conditions, continuous beam cross-section frame and reinforcement adjustment, beam and plate cracking structure processing, the combination of two structural system node design and other key technologies The project has become a typical project for the design of large-scale, large-span and large-span floors. It has provided successful experience for the design of similar sized buildings in China.
