摘要
论述了钢结构的优点和应用前景,对国内外钢结构的重大工程事故进行了分析.经研究发现,每个钢结构脆断事故的实例并不呈由单一因素引起的,而是多个因素共同作用的结果,其中低温、疲劳、高应力集中、焊接残余应力和焊接缺陷是最主要的因素.提出了钢结构设计、制造、施工等环节中应注意的问题.
Advantages and future of steel structures' application are discussed.Many major accidents of steel structures are analyzed.It is found that every concrete example of steel structures' frail fracture is not caused by single factor.It is the result of many factors' coaction.Among those factors,Low temperature,fatigue,high stress concentration,residual stress and weekness of welding are the most important factors.Some problems which should be paid more attention to in design,manufacture and construction are pointed out.
