Comparison of the top of the mid pillar in double span portal frame using rigid connection and hinged connection

钢结构门式刚架应用越来越广泛,比较了双跨门式刚架中柱柱顶刚接和铰接模型,以及两者节点构造、应力储备和结构位移对比,分析了两种模型的优劣性。

Steel structure portal frame is widely used,this article compared the top of the mid pillar in double span portal frame using rigid connection and hinged connection. Node construction,the stress reserve and the displacement of structure with the two models were compared. The advantage and disadvantage of the two models were analyzed.
