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.
