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.

The Finite Element Model

Based on the results of experiment, this paper discusses about the updating and validation of accurate finite element model for damage identification of the steel-concrete composite box girder bridge. Taking a 5 meters long steel-concrete composite box girder bridge as the research object and the finite element model is established. By means of scale model test the updating of the accurate finite element model has been completed and validation is confirmed.

Element Study

A finite element study was performed to investigate the design method of the casual anchor skeleton at the closure of a PC continuous box girder bridge. Based on a finite element model of a certain four spans PC continuous box girder bridge, we found that the stresses of skeleton calculated with the finite model were 5 percent beyond those with the traditional analytic method. Besides, the tensile stresses increased 19 percent and the compressive ones were 14 percent decreased considered the vertical unbalance temperature and both increased 8 percent for the wind, which were totally ignored in the traditional analytic method. So, the traditional analytic method is inaccurate and unsafe for the casual anchor skeleton design, and the general temperature difference, the vertical unbalance temperature and the wind are better to be considered.

Analytical Tools

The paper presents results for finite element analysis of full-sized girth-welded specimens of line pipe and compares these results with the behavior exhibited by test specimens subjected to constant axial force, internal pressure and monotonically increasing curvatures. Recommendations for the ‘best’ type of analytical finite element model are given. Comparisons between the behavior predicted analytically and the observed behavior of the experimental test specimens are made. The mechanism of wrinkling is explained and the evolution of the deformed configurations for different wrinkling modes is examined. It is concluded that the analytical tools now available are sufficiently reliable to predict the behavior of pipe in a manner that was not previously possible and that this should create a new era for the design and assessment of pipelines if the technology is properly exploited by industry.
