- Abstract
- The structural action of a beam is predominantly bending, with other effects such as shear, bearing and buckling also being presented. Due to the more application of corrugated section in steel design, this paper develops a three-dimensional finite element model using LUSAS 14.3 to investigate the effects of web corrugation angle on bending behavior of Triangular Web Profile (TRIWP) steel sections. A triangular web profile (TRIWP) steel section is a built-up steel section made up of two flanges connected to a web plate of triangular profile. 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 are 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 angles (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.
