Abstract:

In this study, composite steel columns' load-carrying capacity will be validated for hollow, equivalent solid, and self-compacting concrete infill of different grades obtained using MATLAB-Vibration toolbox. The complex behavior of composite steel columns plays an important role in seismic design. Natural frequencies and periods are obtained for different grades of infill, including different L/D and D/t ratios. Different slenderness ratios(l/d) of steel columns varying from 2.5-15.0, i.e., both short and long columns filled with M-20, M-30 & M-40 SCC, are considered for the validation. The diameter of the columns is from 26.9mm-160mm, and thickness from 2.5mm-4.0mm is considered.
