摘要
钢结构温度效应敏感,温度变化会引起结构变形和应力。本文基于实际工程有限元分析模型,研究了温度作用对复杂钢结构力学性能的影响,分析结构整体及局部温度变化对关键构件应力以及位移的影响。结果表明:升温对结构影响较大,降温对结构影响较小;整体升温使结构应力增大,结构升温对变形影响较为明显,且上部位移影响大于下部位移影响。
The temperature effect of the steel structure is sensitive,and temperature changes cause structural deformation and stress.Based on the actual engineering finite element analysis model,the influence of temperature on the mechanical properties of complex steel structures is studied,and the effects of structural and local temperature changes on the stress and displacement of key components are analyzed.The results show that the temperature rise has a great influence on the structure,and the temperature drop has little effect on the structure.The overall temperature rise increases the structural stress,and the structural temperature rise has obvious influence on the deformation,and the upper displacement influence is greater than the lower displacement.
