Abstract
This research work is based on strengthening the battened steel columns using light weight concrete as a filling material, and making a comparison between failure load for battened steel columns as a steel only and as a composite columns, to detect the effect of using the light weight filling material in enhancing the columns resistance. Experimental tests for nine steel battened columns with full scale test (3.0 m height) have been carried out, three of these columns were tested as a steel only, and the other six columns were tested after filling them using Expanded polystyrene concrete (EPS concrete), design load for steel columns was calculated according to Egyptian code of practice for steel construction and bridges. It was found that expected failure load for columns according to design load multiplied by safety factor 1.70 is so close to test results, and the failure load for columns filled with EPS concrete is much more than failure load for columns as a steel only, and in some cases it reaches twice of that for steel only case load, and this considered a satisfactory result
