| Abstract: | Destructive test based on real bridge is a directive way of verifying the ultimate bearing capacity of bridge.According to the destructive test of Zuojiabao Bridge in Shanxi Province,which is a RC simply-supported T-girder bridge,the experimental method and process were introduced.Based on the destructive load testing,the real bearing capacity,the regularities of deflection,cracking and stiffness degradation of this bridge were obtained,and the failure mechanism was clarified.The spatial solid FE model was ... |
