| 摘 要： | 针对某大跨度梁,分别采用普通钢筋混凝土梁、钢骨混凝土梁、钢-混凝土组合梁进行计算,并对其受弯承载力、挠度、裂缝、梁高度、用钢量等技术指标加以比较。对比结果表明,大跨结构采用钢-混凝土组合梁在减轻自重、提高材料使用效益、提高抗震性能、降低造价等方面具有明显的优势。由此可进一步加深工程师对此类组合结构的工作机理、特性、应用方面的认识,并供工程设计时参考。

| Abstract: | A large span beam is designed separately adopting reinforced concrete beam,steel reinforced concrete beam,and steel-concrete composite beam.Some indexes,such as bending strength,deflection,crack width,depth of beam,cost,are compared.It is shown that the steel-concrete composite beam has more dominance in this case.The analysis is in focus on steel-concrete composite beam in order to make its principium,characteristic and application clear. |
