Abstract

Cold-formed steel is used for many applications in construction of Industrial building. In this experimental work aims at the study of behaviour of built-up hat section with stiffened web and stiffened tension flange under flexure. The finite strip analysis program CUFSM is used to calculate the section and buckling properties of the hat section. Based on these results the cross section and dimensions of the built up section was arrived at and used in this investigation. The flexural tests were conducted on four specimen’s built-up hat section with stiffened web and stiffened tension flange. The Data acquisition system with Load cell, Strain Gauge and LVDT are used to record the load, strain and deflection measurements. The numerical simulation of the built up section was performed using Finite element Software ANSYS 12.0. SHELL elastic 4 node 63 elements were used and non linear multi elastic behaviour was considered. In theoretical calculations, strength of beams are calculated using Indian Standard IS: 801-1975, BS 5950-1998 (5). The experimental results are compared with theoretical and numerical analysis results. It is observed that this built up section could be used as a flexural member in structures subjected to light and moderate loads.
