摘要
门式刚架跨度及长度较大,在使用过程中温差变化对结构产生较大的温度应力。通过3D3S及MIDAS Gen有限元软件对三联跨门式刚架进行温度作用分析,得出温度作用对横向及纵向的应力及位移的影响较大,温度作用参与的荷载组合为控制组合。在后续的杆件及节点结构设计中考虑温度的影响,采取相应的构造加强措施。
The span and length of the gabled frame are large,in use process,the temperature difference changes have a great temperature stress on the structure.Through 3D3S and MIDAS Gen software to analyze the temperature action of the triple span gabled frame,it is concluded that the temperature effect has great influence on the transverse and longitudinal stress and displacement,the load combination involved in temperature action is control combination.The influence of temperature is considered in the subsequent structural design of members and joints,take some structural measures.
