Flexural response of concrete-filled seamless steel tubes

ABED, Farid Husein | ABDELMAGEED, Yosri Izzeldin | İLGÜN, Abdulkerim

This paper aims to investigate the flexural behavior of concrete filled tubes (CFSTs) made of seamless steel which can handle more pressure than welded steel. Experimental, Theoretical and Finite Element Analyses are utilized for this purpose. The experimental program consists of four-point bending tests of six CFSTs and three hollow steel tubes (STs) for three different Diameter-to-thickness (D/t) ratios of 7.82, 13.5 and 17.5. The test results included are the moment versus displacement and strains, failure modes and ultimate capacities. The contribution of the concrete infill to the flexura ...Daha fazlası
