DYNAMIC ANALYSIS OF COMPOSITE STEEL COLUMNS INFILLED WITH LIGHT WEIGHT CONCRETE (LWC) USING MATLAB (R2013A)

Ramya Shree S C, N. S. Kumar

Abstract: The Composite Steel Column consists of both Steel and Concrete as main components. In this study, the load carrying capacity of CFST will be determined for Light Weight Concrete by developing programs using MATLAB software. The behavior of CFST plays an important role in Seismic design. In this study, the Light Weight Concrete is used as infilled materials of different grades of concrete like M20, M30, and M40. The required data of CFST columns like length, diameter, and weight are taken from different National & International research works, including R&D works carried out at Civil Engineering Research Laboratory at Ghousia College of Engineering, Ramanagaram by previous UG, PG & Research Scholars since 2010 till date. In this study, both Long and Short columns are considered. Percentage errors between Experimental, Analytical values and MATLAB results are studied in detail according to Slenderness Ratio of CFST columns. Results are compared with available codes like EUROCODE 4, ACI, BS5400 and suitable conclusions are drawn.
