Comparative analysis for economy between steel slab base and gusseted base

Abstract

Steel Column Bases are widely used in steel construction for relatively all columns. Column bases are often used in steel buildings and providing economical solutions in cases of large and heavy loads or in other words steel column bases varies in its thickness under various loading conditions. Depending upon the loading conditions, the steel column bases are classified as slab base and gusseted slab base. Since these sections often provide sufficient flexural stiffness to resist bending of base plate and settlement of the column without any extra provision. However, both the column bases are proved to be economical based on the loading conditions which is included in this study. The ultimate capacity of column bases mainly depends on the local behavior of the components, the global behavior of the column as well as the internal forces in the connecting elements. Mainly while considering designing of both column bases the designing procedure is same and it’s observed that the selection of the column base plate depends upon the intensity of load, thickness of the base plate and economy.
