| description | In order to carry out the stability analysis of the in-situ reconstructed steel truss bridge with continuous girder bridge, this study understood the basic overview of the project and the construction scheme, which carried out the construction analysis by numerical simulation method. It is easy to find that the maximum stress of bracket is 75N/mm2 which is less than 110N/mm2.The maximum deformation is 9.2mm, and column height/500=40mm.Stability is calculated as 10.2, which is in accordance with the code. Setting the reinforcement ring at the node part, the local stress is reduced from 285 N/mm2 to 145 N/mm2, which avoids the Z-direction tearing of the steel plate. During the construction stage, the tensile stresses at the top edge of block and bottom edge were 1.4 MPa and 1.5 MPa respectively, and the normal stress meets the construction requirements. The flexural bearing capacity can be satisfied without the temperature T-degree effect in consideration. The study can provide reference for the stability analysis of related cases.s |
