Abstract The jointless bridges includes integral bridges, semi-integral and extended deck bridges. adopts an abutment, its main girder, abutment pile under are fixed together to bear the force together. expansion joint device cancelled, integrity, durability driving comfort of bridge improved. In this paper, a simply supported girder in Fujian Province China is taken as research background, it ...

Continuous rigid frame bridge is a common type of bridge in California, where is a seismically active areas. Main structural features of the bridge, including asymmetry, hinge structure, concretion of girder and piers affect the seismic response of the bridge significantly. In order to evaluate the safety of the bridge under earthquake, the nonlinear models of girder, limiting steels in hinge, ...

Load models are developed for highway bridges. The models are based on the available statistical data on dead load, truck loads and dynamic loads. The paper deals mostly with the static live load. The model is derived from truck surveys, weigh-in-motion measurements and other observations. Simple span moments, shears and negative moments are calculated for various spans. Extreme 75 year loads a...

This paper discusses the ultimate strength of composite plate girders with intermediate inclined stiffeners. The inclination angle stiffener, web opening size and span length are key factors influencing performance girder. study used LUSAS software to develop 20 non-linear finite element models using stiffener different angles, sizes lengths. have an 90°, 75°, 60°, 45° 30°. plates were divided ...
