摘　　要：对目前地震区建筑用钢焊接性能进行了试验研究。结果表明,现有的混凝土结构用钢筋不能满足地震区建筑抗震的要求。提出了应从严限制地震区建筑用钢含碳量及碳当量的意见。The weldability of steels for the use of current buildings in earthquake areas were tested and researched. The results show that the existing reinforcing bars for the use of concrete structures of buildings in earthquake areas can not meet the requirements of earthquake resistance for buildings in earthquake areas. It is suggested that the carbon content and carbon equivalent of building structural steels in earthquake areas must be limited strictly.
