Prototype Jembatan Tipe Plate Girder U (PGU) dengan Lantai Orthotropic Komposit

Abstract

— This paper describes the model of the bridge made of plates, for the girder and for the floor. Both are formed orthotropically which crosses. The girder is formed orthotropically in the longitudinal direction of the bridge, and the orthotropic floor is a transverse bridge. To increase the stiffness of the girder, then the orthotropic floor is casted with reinforced concrete. This tipe of structure is named orthotropic composite Tipe U (PGU) Plate Girder. To prove whether reinforced concrete casted on orthotropic floors can increase stiffness, then a bridge model with a scale of 1:10 was made. Bridge model in loading test. The loading test was performed on orthotropic PGU non-composites and on orthotropic PGU composites. The loading test showed that orthotropic composite PGU had a serviceability of 2.7 times that of orthotropic non compostite PGU service.
