Vibrational Analysis of Composite Steel Tubes Infilled with Conventional Concrete Using MATLab and MIDAS CIVIL Software

Mohammed Ovais Ansari | Dr. N. S Kumar [4]

Abstract: The Composite Steel Column consists of both Steel and Concrete as main components. In this study, the load carrying capacity of the composite steel columns will be validated for Conventional Concrete (CC) of different grades such as M20 M30 M40 by developing programs using MATLAB (R2015a) software. The complex behavior of composite steel columns plays an important role in the seismic design. Natural frequencies and periods are obtained for different slenderness ratios (L/D) of steel columns varying from 6 to 14 i. e, both short and long columns filled with CC are considered for carrying this study. Constant diameter of column of 42.4mm and length varies from 254.4mm to 594.6mm is considered as experimental results are available from different national and international research works including R & D works carried out at Civil Engineering research laboratory at Ghousia College of Engineering by previous UG, PG and research scholars since 2010 till date. Percentage error between obtained experimental values and MATLAB vibration tool box output will be studied in depth along with effect of slenderness ratio. Further analysis for buckling of columns and modelling is carried out with a 3-dimensional non-linear analysis software named MIDAS CIVIL. Obtained results are also compared with available codes of BS and ASCI.
