摘要
山西省晋城市文体馆屋盖结构形式为双钢拱支承的球面钢结构,包括两个互相平行的桁架式钢拱、拱间的联系桁架和球面上由主次钢梁组成的屋面体系。屋面钢梁在外圈支承在预应力钢筋混凝土环梁上,在中间通过V形吊架与钢拱下弦连接。为了平衡钢拱的水平推力,在拱脚之间设计了预应力钢筋混凝土拉杆。
The roof of Jincheng multipurpose gymnasium in Shanxi Province is a spherical surface steel structure with a pair of steel arch supports, including two parallel steel arch trusses, connection trusses in between, and the roof covering system composed of primary and secondary steel girders on the spherical surface. Outer steel girder supporting the roof in the ring prestressed concrete ring beam, in the middle through the V-shaped hanger connected with the lower chord of the steel arch. To balance the horizontal force of steel arch, prestressed concrete tie rods have been designed between arch footings.
