某体育馆网架球节点加固设计

Node Reinforcement Design for A Gymnasium Space Grids

福建某体育馆是一个综合体育馆,其屋盖为椭圆形网架结构,长轴71.8米,短轴59.8米。本文着重介绍该体育馆网架在施工过程中,由于焊接球节点的承载力不足停工,经过分析,找出原因,设计了加固方案,并经过节点实验,验证后实施,网架顺利完工,质量可靠,已经使用多年。

The space grids structure design of synthesis gymnasium in Fujian Province is introduced. The roof is ellipse plane, its major axis is 71.8m and minor axis is 59.8m. The suspense of the building construction is introduced because the bearing capacity of welding hollow globe node is lower. The reason of the shortage is discussed. The reinforcement plan is designed. The node experiment is conducted, Based on the results of the experiment, the space grids structure has completed and used for many years, the quality is credible.
