Research Study on Behavior of Composite Stub Column Experimentally and Analytically
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
The structural behaviour of concrete - filled steel tube (CFST) columns has been investigated using, ANSYS Software, experimental and analytical studies (Rankine’s). The effect of concrete compressive strength, thickness of steel tube, stiffeners a nd longitudinal reinforcement were considered. Specimens that have been studied consist of twenty one circular samples of 150 mm diameter and 5mm thickness and height of 300 mm. The tested samples were studied analytically using workbench by ANSY S (ver. 12) computer program. The results obtained from analytical method shows that, the convergence between analytical and e xperimental method failure load varied from (16.49 to 56.78 %)While the effect of compressive strength of concrete on columns having diameter/thickness (d/t) is 30 . Deformations of columns filled with normal concrete (25 MPa). The effect of diameter/thi ckness (d/t) ratio on the ultimate strength of (CFST) columns will have a reverse action, when of (d/t) decreases the caused incre asing in ultimate load capacity of columns for circular samples depending on the type of stiffened, compressive strength of concr ete and ratio of (d/t).
