in this paper, full scale load test of a horizontally curved steel box-girder bridge is carried out in order to detect structural defects, which reportedly result in unwanted vibrations in nearby buildings. the bridge is tested under the passage of six heavy vehicles at different speeds, so as to determine its static and dynamic responses. a total number of one hundred and two (102) sensors are...

In this research effort, the generalized warping and distortional problem of straight or horizontally curved composite beams of arbitrary cross section, loading and boundary conditions is presented. An inclined plane of curvature is considered. Additionally, the stiffness of diaphragmatic plates has been introduced in the formulation in order to compare with the case where rigid diaphragms are ...

Composite box girder bridges may be a competitive solution under certain constraints due to their efficiency and torsional capacity. However, the cross section deflects transversally, creating longitudinal stresses which reduce capacity of section. Those controlled using cross-frames, but detailing those elements become expensive. The procedure described herein provides useful tool for an effic...

Various theories and analytical formulations were implemented exploited in the 1980s 1990s for design of bridge beams or decks curved horizontal plane subjected to out-of-plane loads. Nowadays, Finite Element Method (FEM) is a valid tool analysis structures with complex geometries and, therefore, development sophisticated not needed anymore. However, they are still useful validation FE models. ...

This paper focuses on Load distribution factors for horizontally curved composite concrete-steel girder bridges. The finite-element analysis software“SAP2000” is used to examine the key parameters that can influence steelgirders. A parametric study conducted load characteristics of such bridge system due dead loading and AASHTO truck using finite elements method. considered in this are: span-to...
