Resum
This paper presents a procedure to improve the accuracy of the classical grillage method for the nonlinear analysis of concrete girder bridges. The procedure uses equivalent element plastic hinge lengths that account for the actual mesh size instead of using a mesh-independent global plastic hinge length. A thorough review of the results of tests conducted on two 1/3-model prestressed concrete girders and a 1/3-model prestressed concrete girder bridge is undertaken in order to model the nonlinea...
