摘　　要：中韩城市馆屋盖结构呈双向自由曲面形态,大空间区域的竖向主受力方向采用单向张弦梁结构,由张弦梁上弦及其平面外的刚性连接系杆共同组成水平刚度较大的单层正交刚架。各榀张弦梁的几何参数随建筑外形变化,跨度主要为45 m、72~90 m。设计时考虑了结构的风荷载和雪荷载敏感性,以及可能存在的极端降温工况,明确了适用于本项目的索松弛控制指标,通过分析验证了结构整体和关键节点的受力性能。The roof structure of the China Korea City Pavilion is a two-way free-form surface.The vertical main force direction of the large space area is an unidirectional string structure.The top chord of the beam string and its rigid connecting tie bars outside the plane together form a single-layer orthogonal rigid frame with large horizontal stiffness.The geometric parameters of the beam strings vary with the building shape,and the span is mainly 45 m,72~90 m.The wind load and snow load sensitivity of the structure,as well as the possible extreme cooling conditions are considered in the design,and the control index of cable relaxation applicable to the project is defined.
