Experimental Investigation of Cold-Formed Steel Section- Flexural Member with Triangular Web

The present paper work dealt with the investigation on the behavior of cold form steel built up I - section with triangular web corrugation at varying depth. The effect of web corrugation and hw/tw ratio on the flexural strength of cold formed steel (CFS) lipped I section was presented in this paper. The length of the specimen was kept constant for 2000 mm and hw/tw ratio was varied from 166 to 250 keeping all other parameters as constant. In total three specimen were experimentally tested under two point loading with triangular web corrugation by considering simply support condition. The experimental results are verified with finite element analysis using ANSYS software. The results obtained from test experiments and ANSYS software were compared with the predicted Indian Specifications (IS 801- 1975). The experimental result shows that the flexural capacity of the triangular web was larger than flat web. Also the effect of hw/tw ratio on the flexural strength capacity was studied and discussed. Due to the provision of triangular web corrugation, there was no failure in shear zone or in web portion.
