DEVELOPMENT OF A SIMPLIFIED METHOD OF LATERAL LOAD DISTRIBUTION FOR BRIDGE SUPERSTRUCTURES

A new simplified method for establishing the live load design moments in most common types of bridges is presented. The proposed method was developed by using orthotropic plate theory and was checked by the grillage analogy method. The basis of the method together with the details of development methodology are discussed. Different variables which may affect load distribution in bridges were examined, and the main variables governing the distribution factors were selected for the present study. The study deals mainly with single span right bridges which can be analysed using the orthotropic plate theory or grillage analogy. However the limits of applicability of the distribution factors to continuous and skew bridges and bridges with diaphragms and edge beams are also discussed. /Author/
