The Application of Grillage Method in Analyzing Box Girder Structure

Yi Li

Abstract

This paper introduces the theory of grillage method, principles and grillage beam meshing as well as the performance calculation of grillage member section in detail. 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.
