| Abstract: | 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 performed,with the distribution law of the shearing forces of the chord bolts gained and the calculating expression... |
