Analysis and application of grillage method in the curved box-girder bridge

Grillage method is a kind method of space structure analysis to simulate well curved bridge structure.Because of its clear basic concepts,low computational cost,and internal force calculation results which can be used directly by calculating according to standard etc.,it is often applied to the design of width,inclined,curved girder bridge.This paper introduces the basic grillage theory to be applied to the box beam section,and the basic theory of midas civil 2010 was used to verify the feasibility of grillage method,providing reference for the designers to the similar bridge structure analysis.
