摘　　要：我国钢结构用钢材以板材为主,热轧H型钢(RH)在钢结构上的应用增长缓慢,其中热轧H型钢用量仅占H型钢总量的15%,占比偏低,其余为焊接H型钢。文章从焊接H型钢(BH)与热轧H型钢(RH)的规格、种类、生产工艺、残余应力、R角处组织、优劣势及未来发展趋势等几方面进行对比分析,并提出热轧H型钢在建筑钢结构上应用瓶颈的几点对策。In China,the steel for steel structure is mainly plate and applications of hot rolled H beam(RH)in steel structure is growing slowly.The use level of RH accounts for only 15%of total amount of H beam,which is relatively lower and the rest is welded H beam(BH).In this article,the specifications,types,production processes,residual stresses,microstructure at R corner,advantages and disadvantages as well as future development trends of BH and RH are compared and analyzed.Moreover,several countermeasures for the application bottleneck of RH in construction steel structure are proposed.
