Effect of Small Radius on the Performance of Curved Steel Box Girder Bridge

According to the design of a three--span 38m+6om+38m bridge of cambered steel box beams, it is mainly presented that the construction methods of an urban viaduct of cambered steel box beams, its paved floor and treatment of shear lag effect., through the six series of 20 specimens calculation and analysis, simulation different local structures curved steel box girder bridges reflect more accurately the role of various factors in the mechanical behavior. This in-depth analysis of the different local structures in space curved steel box girder bridge performance, for guiding the engineering design has a certain reference value for further study curved steel linear and nonlinear mechanical properties and stability lay a good foundation.
