Abstract:

Steel has become the predominate material for the construction of bridges, buildings, towers, and other structures. Steel exhibits a desirable physical property that makes it one of the most versatile structural materials in use. Its great strength, uniformity, light weight, ease of use, and many other desirable properties makes it the material of choice for numerous structures such as steel bridges, high rise buildings, towers, and other structures. Column is one of the important structural elements in any type of Structures. Steel columns sometimes cannot provide the necessary strength because of buckling. The steel sections manufactured in rolling mills and used as structural members are known as rolled structural steel sections. The steel sections are named according to their cross sectional shapes. Rolled steel Sections the most desirable members are those with large moments of inertia in proportion to their areas can be used into a wide variety of shapes and sizes to avoid torsional buckling. This paper presents the findings from an experimental study on steel column subjected to constant axial force. Three Different categories of cross-sections such as I section, cruciform section (Plus section) and modified cruciform section (Double Tee-inverted) were designed. Totally Nine scale model columns were fabricated based on the proposed design methodology and were subjected to Axial Loading. Parametric studies such as Load Vs deflection, failure behaviour of short columns were discussed. From the experimental study it was concluded that the cruciform section performed well than modified cruciform section.
