Girder Bridge

<p>The Cortenoeverse bridge is a multi-span pre-stressed concrete box girder bridge near Zutphen, the Netherlands. Following the discovery of certain damages at the sides of the bridge where post- tensioned tendons are stressed, several repairs have already taken place. The Dutch agency Rijkswaterstaat (RWS) still deemed it desirable to further investigate the structural safety and usability of the whole bridge during the residual service life. Subsequently. ABT was commissioned to perform a verification calculation. Finite element analysis (FEA) was applied to analyse the structural behaviour of the bridge. Compared to analytical methods, FEA can simulate the occurring forces more accurately and give more insights into the structural behaviour of the bridge. The bridge was modelled using 2.5D curved shell elements with embedded reinforcements subjected to post- tensioning loads. An overview is given for the FEM model, the calculation procedure and the results.</p>

Girder Bridge

A simple box girder bridge with spans 25m is being constructed on the No.2 road of a project of PanZhiHua Steel. A Bailey trussed girder is constructed under the bridge to assist its construction. The paper makes spatial finite element analysis about the Bailey trussed girder. Firstly, the spatial finite element model is built. Then the force, stress and displacement of the girder under six box girders’ self weigh and the construction load are analyzed in detail. Lastly, the construction scheme is optimized. After optimization, all indexes of Bailey trussed girder can meet code requirement.

Due to its outstanding aerodynamic shape and light weight, the trapezoidal cross-section flat steel box girder with orthotropic decks and thin-walled longitudinal stiffeners of trapezoidal cross section are widely used in long-span suspension bridges in the world. However, because of the geometrical characteristics and the relative flexibility of their components, these structures may be quite susceptible to traffic loadings that fatigue cracks tend to appear in these structures. In this paper, Jiangyin Bridge is used as a case study to investigate the fatigue performance of the steel girders of suspension bridge Jiangyin Bridge is the second longest bridge in China, which has the main span of 1385m. The stress analysis of steel box girders is firstly carried out based on the analysis of fatigue life. Fatigue assessment method is proposed on the basis of in-situ measurement data combined with finite element analysis. A complete fatigue assessment is made in this paper. Key words: flat steel box girder; orthotropic decks; finite element analysis; fatigue assessment

The safety evaluation of the aqueduct in many years of operation is often performed to determine the structural operational behaviour so as to provide a scientific basis for further reinforcement or reconstruction. The missing of the original design data due to the long construction period provides great challenging in the structural safety evaluation of the aqueduct. Taking a hyperbolic arch aqueduct in China as an example, we first rebuilt the aqueduct model using the three-dimensional (3D) point cloud from the three-dimensional laser scanning technology. Coupled with the on-site safety inspection, the 3D finite element analysis was then performed to learn the stress performance of the aqueduct body and its supporting structures, so as to achieve the purpose of safety evaluation of aqueduct structure in a whole.

Finite element analysis have been carried out in order to study the mechanical properties of the joints between elevated columns and truss column in substation frame. Firstly, the numerical results and the experimental ones were compared to verify the efficiency of the FEM model. Then, the whole process of elastic-plastic analysis was carried out to the prototype structure. The results show that when the bottom of the elevated column was yielding, the stress of the stiffeners at the joint is small, which can meet the design principle of “strong joint - weak member” criterion. Furthermore, when the structure enters into the elastic-plastic stage, the stress in the upper stiffeners at the horizontal load direction is large and most of them yield, but the stress in the plane gusset plate of the joint is still small.
