波形钢腹板桥的受力分析与比较

Stress analysis and comparison of corrugated steel deck bridge

以朔州市振武街桥为工程背景,分析对比了波形钢腹板桥和传统混凝土腹板桥在重力作用下的挠度、顶底板正应力的差异性,通过论证表明,波形钢腹板—PC组合梁桥,充分发挥预应力混凝土和钢材这两种材料的性能,较传统混凝土桥及钢结构桥在诸多方面具有优势,具有较好的应用前景。

Based on the background of Zhenwu Street Bridge in Shuozhou City,this paper analyzes and compares the difference of deflection and normal stress of top and bottom slab between the corrugated steel deck bridge and the traditional concrete deck bridge under the action of gravity.Through demonstration,it shows that the corrugated steel web PC composite girder bridge is superior to the traditional concrete bridge and steel structure bridge in many aspects and has a good application prospect.
