The Effect of Web Corrugation Angle on Bending Performance of Triangular Web Profile Steel Beam Section 

Full Paper(PDF, 192KB) 


Abstract: 

The structural action of a beam is predominantly bending, with other effects such as shear, bearing and buckling also being present. Due to the more application of corrugated section in steel design, this paper develops a threedimensional finite element model using LUSAS 14.3 to investigate the effects of web corrugation angle on bending behavoiur of Triangular Web Profile (TRIWP) steel sections. A TRIWP steel section is a builtup steel section made up of two flanges connected to a web plate of triangular profile. This TRIWP steel section is a modified section from trapezoidal web profile steel section where the eccentric stiffeners of trapezoidal section was eliminated and changed to slanting stiffeners. Thin shell element was chosen to represent the element type of the model. Two sizes of flat webs (FW) as control specimens and two sizes of TRIWP which is 200×100×6×3 mm and 180×75×5×2 mm section were used. Each of beam section was modeled using several spans such as 3 m, 4 m and 4.8 m and different corrugation angle (150,300,450,600 and 750). It was noted that deflection of 450 and 750 web corrugations angle be the lowest deflection value either in minor or major axis of TRIWP steel section. It means that the TRIWP steel section is stiffer when the web corrugation angle is 450 or 750. In other word, TRIWP steel section has a higher resistance to bending in minor and major axis when the web is used in both corrugation angles. It can be concluded that the changes of eccentric stiffeners to slanting stiffeners is significant to the bending behaviour of the TRIWP steel section. The introduction of slanting stiffeners shows a greater strength compare to corrugated section by using trapezoidal web.
