Behaviour of sfrc in filled light Gauge steel box columns and beams

Abstract

The main objective of the study is to investigate the behaviour of newlineHollow Plain Cement Concrete PCC and Steel Fiber Reinforced Concrete newline SFRC in filled stub short and medium columns subjected to axial and newlineeccentric loads and beams subjected to flexure Experimental Theoretical and newlineNumerical investigations have been carried out newlineIn the first phase experimental investigations were carried out to newlinestudy the behaviour of hollow PCC and SFRC in filled light gauge steel stub newlineshort and medium height columns Seventy eight experiments were newlineconducted out of which five tests were on stub columns five tests were on newlineshort columns and sixty eight tests were on medium height columns newlineSpecimens were fabricated from light gauge steel sheets continuously welded newlineat the middle along its length For PCC in fill M20 grade concrete was newlinechosen and for SFRC in fills newline newline
