NUMERICAL INVESTIGATION ON FLEXURAL BEHAVIOUR OF COLD FORMED STEEL I SECTION WITH TRIANGULAR CORRUGATED WEB

The objective of this paper is to study the flexural behaviour of cold formed I –section with triangular corrugation. The effect of parametric change on the flexural strength of cold formed steel (CFS) I section is presented in this paper. The web is corrugated at regular interval into a triangular shape along the length of the beam. Totally twelve specimens are theoretically and analytically analysed by changing depth of corrugation, hw also span. All specimens are numerically analysed under two point loading with simply supported condition. The theoretical results are verified with finite element analysis using ABAQUS software. Theoretical analysis is done with code provision of AISI S100-2007, AS/NZS 4600:2005 specification. Within the parametric study the effect of corrugation in web on the flexural strength capacity is discussed and presented
