The finite element software Midas / Civil is used to establish the continuous box girder bridge model for the comparative analysis between the grillage method and single girder method, and the results show that the precision of grillage method can meet the needs of the engineering design.
This paper discusses the grillage method frequently-used in detail, and uses the Midas / Civil to establish the model and uses the examples to deepen the understanding of such method.
This paper establishes the model with Midas Civil.
Conclusions Through the introduction to the theory of grillage method and the engineering example comparative analysis between the grillage method and single girder method with Midas Civil, we can draw the following conclusions: (1) The analysis of this engineering example shows that the accuracy degree of grillage analysis depends on the exact simulation of the grillage stiffness, grillage member unit bending, shear and torsion characteristics
Its calculation accuracy can meet the design requirements; therefore, grillage method is a viable analysis method in the practical applications in engineering.
