摘要
结合实例探讨了采用公路桥梁新旧规范计算钢筋混凝土简支空心板梁时,在汽车荷载效应、冲击系数、材料强度取值以及挠度计算方面的一些主要异同,分析了差别产生的原因,验证了新规范的安全性、合理性。
The main differences in calculation on vehicle load effects,impact coefficient,the value oi material strength and bending deflection of a reinforced concrete simply supported hollow slab beam between adopting new code for design of highway bridges and adopting old code are discussed by examples. The difference causation is studied, and the safety and rationality of new code for the design of highway bridges are verified.
