Abstract - Steel is one of the most sustainable construction materials. Its strength and durability coupled with its ability to be recycled again and again without ever losing quality make it truely compactable with long term sustainable development. Steel construction is placed in top list because it safeguards the building against damage in case of climatic effects like earthquakes and cyclones. In steel structures, channel sections are widely used because it has more shear capacity. The flexural behaviour of channel section ISMC75 at different loading conditions is studied in this experiment. The specimen was tested under in a loading frame by applying loads at one third points for its pure flexural behaviour. From the experiment it was found that, the load carrying capacity of the channel section when applying load on flange portion is 47% higher than the load applied on web portion. Key Words: Steel construction, Channel section, Shear capacity, Two point Loading, Flexural behaviour.
1.INTRODUCTION Structural steel is a solid material used for steel construction, which is fashioned with a specific shape following certain standards of chemical composition and strength. They can also be defined as hot rolled produces, with a cross section of different forms like angles, channels, beams and joints. There has been an increasing demand for structural steel for construction purposes in the United States and India. The structural steel all over the world predominates the construction development. This material has been comprehensively used in various constructions all over the world because of its various specific features that are very much preferably suited for construction. Structural steel is long-lasting and also has unique physical property, ductility, because of which it is able to take up large deformations beyond the elastic limit without fracture. It can be well molded to give the preferred shape to give an ultimate appearance to the structure that has been constructed .Several types of structural steel sections are used in construction like beam, channel, angles and flats.

When the beam is adequately supported against lateral buckling, the beam failure occurs due to the yielding of the material at the point of minimum moment. A significant variation between steel and concrete constructions is that the designer has more control over the shape of reinforced concrete elements. For building a steel structure normally to use standard rolled sections. The main advantages of steel structures are their smaller weight to strength ratio, speed of erection, dismantling and its scrap value. The steel beam is thus capable of reaching its plastic moment capacity under applied load. In this paper reports only the flexural behavior of steel channel section with load at web and flange portion. The purpose of this investigation was to study the flexural behavior of section with load at web portion in comparison with load at flange portion.
1.1 Steel Channel section Steel channel sections are used preferably as supports and controller barriers. These are roll-formed products. The main metal used for making channels is steel along with aluminum. J, Hat, U and C sections are the certain variants that are available in the channels category. A major optional of the channel is the mild steel channel. Such channels are commonly used in heavy industries. They are commonly used in the heavy machinery industry and automotive industry too.
