Studying The Behaviour Of Columns Of Steel Framed Structure Using Various Steel Sections

The present study represents the comparison between conventional steel sectional columns and tubular steel section column. Therefore, total 6 number of models of 12-Storey Building were analyzed in staad.pro (designing tool) having different conventional and tubular steel section as a column. Different bracing systems (such as cross and v bracing) have also been adopted for lateral stability. The performance of all the models has been studied by performing dynamic seismic analysis in zone IV and has been evaluated in terms of structural parameters of columns i.e. axial force, bending moment, displacement. The effectiveness and economy of conventional and tubular steel section with and without bracing system has also been recorded in order to get the final outcome of the study.From the final results of the present study, it has been concluded that the ratio of maximum displacement and total steel quantity comes out to be 1.16 and 0.74 for the buildings without bracing (i.e. Type B to Type A) respectively. Ratio of maximum displacement and total steel quantity is 0.98 and 0.78 for the buildings having cross-bracing (i.e. Type D to Type C) respectively. Ratio of maximum displacement and total steel quantity is 1.05 and 0.80 for the buildings having cross-bracing (i.e. Type F to Type E) respectively. Therefore, tubular sections prove to be more economical than conventional sections as it saves 20% to 30% material cost.
