Experimental and Analytical Study of Built Up section of Cold Formed Steel (CFS) by Bolted Connection

Abstract

This paper involves the experimental and analytical study of flexural strength of Cold Formed Steel (CFS) sections by using bolted connection. The analytical investigation of the built up section was carried out using finite element analysis software ABAQUS (Standard version 6.10) with 4 number of built up sections. The specimens consists of beams made of one or more Cold-Formed Steel (CFS) profiles namely, C (lipped channel) profiles and U (channel without lip) profiles, whereas the channel sections are connected along the flanges with bolts (M10). The experimental investigation shows the bending strength and behavior of CF built-up sections where, Four models are created in two groups, the first group of two specimens with 2mm thickness and second group of two specimens with 3.15 mm thickness with varying web and flange dimensions taken from IS 811-1987. They are analyzed under two point loading conditions. The result shows the modes of buckling failure, their influence on the bending strength and behaviour of CF built-up sections. The influence of the height, thickness and span of the beams was studied and then experimental results are compared with the analytical results.
