摘要
"321"装配式公路钢桥是一种下承式的销接桁架桥,其弦杆螺栓的受力分析是使用"321"钢桥的工程师要面临的难题之一,关系到钢桥的安全使用问题。利用有限元软件SAP2000对加强型"321"装配式公路钢桥进行结构分析,介绍了分析步骤,得到了弦杆螺栓的剪力分布规律和最大剪力计算公式,为同类结构的受力分析及设计提供理论依据。
The force analysis of the chord bolts of Type-321 Assembled Steel Bridge, which is an assembled pin-jointed, through truss bridge, is one of the most difficult problems facing engineers who are going to use the bridge and which is closely related to the safety of the Bridge. With the help of the software SAP2000, a structural analysis of Type-321 Assembled Steel Bridges with chord reinforcements is per- formed,with the distribution law of the shearing forces of the chord bolts gained and the calculating ex- pressions of the maximum shearing force given. The research result lays a theoretical basis for the analysis of similar structures and structural design.
