Analysis of Concrete Filled Double Skinned Tubular Columns Infilled With SCC by Using ANSYS

The main components of Concrete Filled Double Skinned Tubular (CFDST) Column consist of both Steel and Concrete. in the present study carried out on Concrete Filled Double Skinned Tubular (CFDST) Column with an infill of Self compacting Concrete (SCC) to determine maximum load carrying capacity that can be taken by the CFDST columns. The Validation is carried out to determine the load carrying capacity of the CFDST columns in which grades of MS steel i. e. Fe 250 with the Self compacting Concrete (SCC) of various grades such as M30, M35, M40, M45, M50, M55, M60, M65, and M70 by us ng Ansys software. The complex behavior of CFDST columns plays a dominant role in the seismic design. Results are obtained for various slenderness ratios, i. e. (L/D) of CFDST columns vary ng 8, 9.2, 10.4, 11.6 to 12.8 of the Diameter for column where 50mm as the diameter of external skin with the internal skin of 20mm in Diameter. Length of specimen varying 400mm, 460mm, 520mm, 580mm, and 640mm. Similarly for various slenderness ratios, i. e. (L/D) of CFDST columns vary ng from 10, 11.5, 13, 14.5, and 16, of diameter for column where 40mm as the diameter of external skin with the internal skin of 20mm in diameter. Vary ng length from 400mm, 460mm, 520mm, 580mm, and 640mm i. e. , both short and long CFDST columns filled with SCC were considered for carrying this study. diameter of the column varying from 50mm to 40mm and length from 400mm to 640mm were considered. As partial experimental results are available. From different national and inter-national 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 Ansys output will be studied in depth along with effect of slenderness ratio (ovais, 2018). Further Obtained results are also compared with available codes.
