Beschreibung:
<jats:p>This paper considers material nonlinearity and geometric nonlinearity,study in-depth the force performance using the finite element method for space curved steel box girder bridge, 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.</jats:p>
