摘要
本文根据《钢结构设计规范》(GBJ17-88)中的规定,按极限状态设计法对钢-混凝土组合梁与非组合梁进行了工程实例设计计算对比,表明组合梁结构有很大优越性,比非组合梁结构可降低梁高,提高结构刚度,从而可降低工程造价,加快施工进度,本例计算可少用钢材30%以上,挠度减少15%～65%。
This paper presents the comparison between two design and calculation examples of the compositebeam and noncomposite beam designed according to the limit state theory and 'design specification forsteel structures' (GBJ17-88). It shows that the composite beam has such advantages as smaller depth,higher structural stiffness, lower costs and shorter construction time. Its demand for steels can beveduced by more than 30%, and its deflection by 15% to 65%.
