摘　　要：热轧H型钢是一种断面力学性能优良的经济型断面钢材,而焊接是常用的对接方式之一,因此研究不同焊缝形式下的残余应力分布,对提高钢结构的承载力有重要意义。利用ANSYS有限元软件对H型钢五种平接焊缝形式下的残余应力进行了数值模拟,得出了一些有意义的结论,为热轧H型钢的应用提供有价值的参考。Hot-rolled H-beam is kind of economic section steel that has excellent mechanics capability.Welding is a common way of joining together,studying residual stress distribution of different welds has important meaning to improve the load-carrying capacity of steel structure.Building its model by ANSYS,simulating the process of welding and researching its residual stress distribution under five kinds of weld,can give reference for the application of Hot-rolled H-beams.
