Researching on Buckling Performance of Corrugated Steel Web. American Journal of Civil Engineering. Vol. 6, No. 1, 2018, pp. 5-10. doi: 10.11648/j.ajce.20180601.12 Received : October 7, 2017; Accepted : October 18, 2017; Published : December 6, 2017 Abstract: The paper mainly studies buckling performance about corrugated steel web composite box girder of corrugated steel web under the action of a shear. Compare the two results of the corrugated steel web that calculating critical buckling stress through Abaqus finite element software calculating and theory formula. Obtain buckling strength of the model by giving the model initial defects under the elastic condition merely. In this paper, research trend of the buckling strength of corrugated steel web plate through changing the thickness of corrugated steel web, Angle, length of straight and wave height and the size of the corrugated steel web in practical engineering designing provide a certain references. Keywords: Corrugated Steel Web, Buckling Strength, Elastic Condition, Abaqus 1. Introduction With the increase of span of bridge, box girder is widely used as the superstructure of bridge, which has the characteristics of large bending and torsion rigidity. But there is a problem that the weight of superstructure increasing with the increase of span, so reducing the weight of the bridge superstructure has become an important direction in the technology of bridge structure. There are two aspects to reduce the weight of superstructure that reduce the thickness of the roof and floor. Because the roof and floor need to meet the requirements of bridge bending design, the thickness of the roof and floor of the bridge is less optimized, while the web needs pre embedded prestressing tendon, then it needs to retain a certain thickness. So the French proposed a project that replace traditional concrete webs of prestressed concrete box girder with plane steel plate, and inflict prestressing force on pre-stressed beam through tension external prestressing tendons. [1, 2] The kind of steel-concrete composite bridge has some advantages that less weight, improve the efficiency of the using materials through making full use of potential of materials, improve the performance of construction. But because of shrinkage and creep of concrete roof and floor are restricted by steel web beam, prestressing force is transferred toward webs, which reduces utilization ratio of prestressing force.[2] In 1975, Camernon Bernard proposed that replaced plane steel web with corrugated steel web.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
