Experimental Study on Flexural Behaviour of Cold Formed Steel Channel and I Sections Providing Angle Stiffener on the Web
Background: Different products are manufactured from Cold Formed Steel (CFS) are used in the different field of our daily life; in the home, the shop, the factory, the office, the car, the petrol station. These products have many uses ranging from ‘tin’ cans to structural frame, building members. This investigation presents the analytical study and theoretical study of the behaviour of flexural strength of CFS sections. Methods: Analytical study of CFS section was done by using FEM software (ANSYS Multiphysics Utility – CIVILFEM). Here two Channel sections and two built up I sections are fabricated. Built up I sections are formed by using symmetric channel section with the help of bolts provided in the web part of the section. One of the built up I section and C section are provided with angle stiffener to increase the flexural strength. The analytical results are compared with theoretical results according to IS 801:1975. Findings: From the study it is found that the maximum moment are occurring in between the one third of span to two third of span of the subjected sections. The moment in the zone between the two point loads are same and that portion is known as pure bending zone. Flexural strength is increased by providing angle stiffener throughout the length of the sections at the spacing of 40 mm between two stiffener and for I section and Channel section total stiffeners are provided respectively 24 and 12. Applications: Further works can be focused on determining the behaviour of the channel and built up I section with increasing web thickness, flange thickness and increasing the stiffener dimension. Another useful can be done by using diagonal stiffener with the temperature effect which may change the behaviour of channel and built up I section.
