EXPERIMENTAL INVESTIGATION OF STRENGTHENED SHORT CONCRETE COLUMNS

Behaviour of FRP strengthened concrete columns under eccentric compression loading

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...

An Analytical Method for the Evaluation of the RC Columns Capacity Strengthened by Concrete Overlays

Experimental analysis of reinforced concrete columns strengthened with self-compacting concrete and connectors Análise experimental de pilares de concreto armado reforçados com concreto auto-adensável e conectores

© 2012 IBRACON There are many problems involving cases of destruction of buildings and other structures. The columns can deteriorate for several reasons such as the evolution and changing habits of the loads. The experimental phase of this work was based on a test involving nine reinforced concrete columns under combined bending and axial compression, at an initial eccentricity of 60 mm. Two co...

An Analytical Method for the Evaluation of the RC Columns Capacity Strengthened by Concrete Overlays

Cyclic and Monotonic Behavior of Strengthened and Unstrengthened Square Reinforced Concrete Columns

The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...
