| Abstract: | In the comparison and selection of steel beam construction schemes of Penkete No.2 Bridge,the ABAQUS finite element software was used to analyze the overall stress and displacement distribution of the steel beam under each construction scheme,and the influence of different construction schemes on the steel beam construction accuracy control,safety risk control and bridge bearing capacity was quantitatively analyzed based on the specific data,so as to select the optimal scheme.The results show that the stepwise lifting scheme can improve the durability and anti-fatigue performance of the steel beam compared with the jacking scheme.The hoisting scheme of composite beam can avoid the stress concentration of steel beam and improve the load of completed bridge.After comprehensive comparison and analysis,the combined beam hoisting scheme is selected as the optimal scheme. |
