Abstract:

Experimental investigation was carried out on Hybrid double skinned steel tubular columns consisting of an outer and an inner tube made of steel, with space in between filled with the different grades of self-compacting concrete as infill. Analysis was done for the ultimate load carrying capacity of tube subjected to monotonic loading, including the failure pattern up to the ultimate load. In order to save the time and cost of experiment, Taguchi’s approach was adopted. Results were generated using Taguchi’s method-a new technique to get mean effects plot. Analysis was carried out using ANOVA (Analysis of Variance) technique with the assistance of Mini Tab v15- a statistical soft tool. Results were verified after conducting preliminary nine combination experiments as per L9 orthogonal array and linear regression models were developed. Comparison for predicted and experimental output is obtained from linear regression plots are presented in this paper.
