某青少年体育馆结构楼盖选型探析

Structural design of floor and beam system for a gymnasium

某青少年体育馆的一层游泳馆上空为36. 2m跨度的混凝土楼盖,楼盖建筑使用功能为运动馆。经方案比较,最终采用型钢混凝土梁代替预应力混凝土梁的新方案,同时需加大柱网间距,边柱采用型钢混凝土柱。经过计算证明了,30m^40m跨度的混凝土楼盖采用型钢混凝土结构是合适的。

Above the swimming hall of a youth gymnasium is a concrete floor with a span of 36.2m.The function of the floor is a sports hall.After comparing different schemes,the new scheme of using steel reinforced concrete(SRC)beams instead of prestressed concrete beams was finally adopted.At the same time,it was necessary to increase the spacing of the column grid,and to replace the side columns with steel reinforced concrete(SRC)columns.Calculations have proved that it is appropriate to adopt a steel reinforced concrete(SRC)structure for the concrete floor with a span of 30-40m.
