Abstract

Abstract: By treating the deck and the rib-beam as a wholeand by using the displacement modes of the Mindlin plate element and the8-node Serendipity element in the calculationa curved plate element with rib-beam was constructed in view of the nonlinearity of the structure．In the Mindlin plate elementthe displacement and the angular displacement are interpolated independently．In the proposed element modelthe effect of rib-beam is taken into accountand the slab and rib-beam are combined into one element．Thereforethe displacement incoordination of the joint in the nodes of the plate element and the rid-beam element no longer exists．Numerical examples show that the proposed method is of the advantages of reliable calculation results and less freedom degreeand it is applicable to the nonlinear spatial computation of the large-span curved girder bridge．

Key words: curved girder, rib-beam supported curved plate element, nonlinearity
