摘要
通过MIDAS FEA建立波形钢腹板组合箱梁的有限元模型,研究了加劲肋的宽度、厚度、布置的数量以及布置方式对波形钢腹板组合箱梁抗扭性能的影响。结果表明:波形钢腹板插入加劲肋可以对波形钢腹板组合箱梁的抗扭性能有较大提高;增大加劲肋的板厚、板宽以及增大加劲肋布置的数量可以提高波形钢腹板组合箱梁的抗扭性能;相同宽度、高度、厚度的波形钢腹板加劲肋,采用双面布置会降低波形钢腹板组合箱梁的抗扭性能。
The finite element model of composite box girder with corrugated steel webs was established by MIDAS FEA, and the width, thickness, quantity and arrangement of stiffener ribs on the torsion resistance of composite box girder with corrugated steel webs were studied.The research results showed that torsional performance of composite box girder with corrugated steel webs could be greatly improved after inserting stiffeners.Increasing the thickness of stiffeners, the width of the stiffeners and the quantity of the stiffeners could improve torsional performance of composite box girder with corrugated steel webs. When the stiffeners of the corrugated steel webs did not change the width, height, and thickness, the double-sided arrangement would reduce the torsional behavior of composite box girder with corrugated steel webs.
