| Abstract: | Grillage method is an effective method for spatial analysis on bridge structure.According to the principle of the grillage method,the mechanical behavior of reinforcement with section changing method for T-girder bridge is analyzed.Combining with the specific engineering example,the contrasting analysis is carried out between the grillage method and 2D beam finite element method.The contrastive results show that the application of grillage method to the reinforcement with section changing method for T-girde... |
