behavior of frp-confined reactive powder concrete columns under eccentric loading
Authors
abstract
fiber reinforced polymers (frp) have widely used for the purposes of enhances strength and ductility of concrete columns. proper design of such hybrid columns, however, requires a better recognition of the behavior of concrete columns confined with frp. in this paper, the influence of frp thickness, concrete compressive strength, and column size on the performance of eccentrically loaded reactive powder concrete (rpc) columns confined with frp is investigated. in this regard, five different frp thicknesses, three types of column sizes, and concrete compressive strength values ranging from 140 mpa to 180 mpa are considered. for this purpose, two-dimensional nonlinear finite element analyses are carried out so as to predict the behavior of frp-confined rpc columns. opensees software is employed to analyze the considered columns. to validate finite element model, the numerical predictions are compared with the experimental data. the study, from a numerical point of view, derived some important relevant conclusions regarding the behavior of rpc columns confined with frp.

This paper presents results of testing eccentrically loaded columns externally wrapped with two types of materials. Six cylindrical (205 mm diameter and 925 mm height) plain columns were cast and tested. Half of the columns were wrapped with GFRP and the other half with CFRP. All columns were tested by applying an axial load at 50 mm eccentricity. In each group (GFRP or CFRP wrapped) of columns...

This paper presents results of testing 16 specimens, 12 of which as columns under different eccentricities and four as beams under four point loading regime. All 16 specimens were circular in cross section and were made of reinforced concrete. Four specimens served as reference specimens and were just made of reinforced concrete. The next four specimens were wrapped with Carbon Fibre Reinforced...

This paper presents the results of an experimental study into the behavior of concrete-filled steel tube columns confined by fiber-reinforced polymer (FRP). Eleven columns were tested to investigate the effects of the FRP layer number, the thickness of the steel tube and concrete strength on their load capacity and axial deformation capacity. The experimental results indicated that the FRP wrap...

This paper provides a review of some of the progress in the area of fiber reinforced polymers (FRP)-strengthening of columns for several loading scenarios including impact load. The addition of FRP materials to upgrade deficiencies or to strengthen structural components can save lives by preventing collapse, reduce the damage to infrastructure, and the need for their costly replacement. The ret...
