Field Test and Analysis for the Static and Dynamic Behaviour of Multi-box Steel Concrete Composite Girder Bridge
Taking the four-span 40m simply supported multi-box steel-concrete composite girder bridge in the Project Ⅱ of Qiushi Expressway in Hangzhou as the background, this paper analyzed the static and dynamic behaviour of the bridge by FEM, then finished a field test study for the bridge.Finally, comparing the test values with the results obtained from FEM analysis, it was verified that the rigidity transverse beam method with infinte stiffness is also adaptive to caculating and predicting the load transverse distribution of the multi-box steel-concrete composite bridge.Steel diaphragm and stiffening rib of the multi-box steel-concrete composite bridge can improve the flexural capacity of bridge to some extent, so these contributions should be reasonably considered during the design stage in order to reduce the engineering cost.The measured modes agree well with the results from FEM.
