This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete filled tubular columns with elliptical cross-section, the main objective of this paper is to compare the behaviour of such innovative cross-sections under ambient and high te...

Abstract Glass fibers reinforced polymer (GFRP) were used to longitudinally and transversally 12 columns while the other 4 with steel or GFRP as reference specimens. This research dealt several parameters under different loading conditions, such reinforcing material spacing between ties. study aims find out ability of bear loads. In addition, investigate mode failure in these their appropriaten...

Glass fiber reinforced polymer (GFRP) pultruded profiles are being increasingly used in civil engineering applications. Although they offer several advantages over traditional materials, such as high strength, lightness and non-corrodibility, GFRP profiles present low elasticity and shear moduli, which together with their slender walls makes them very prone to buckling phenomena. Several previo...
