Abstract

The objective of this investigation was to examine the shear behavior of axially loaded fibrous reinforced concrete short columns under double curvature bending. Eleven columns with modeled dimensions of 6 in. by 41/2 in. with only different fiber volume fraction V_f and shear span ratios were tested under double curvature bending.

The material properties of fibrous concrete is briefly discussed on how the addition of fibers benefits the concrete mix. The results of the compressive and tensile behavior of fibrous concrete is presented. The behavior of bending on reinforced fibrous concrete columns is also briefly discussed.

Previous investigation results, equations, were modified to reflect the presence of fibers in the reinforced concrete columns. Reinforced fibrous concrete column interaction diagrams are shown. The benefits of the addition of fibers is explained lath these diagrams. Both axial tension and compression are considered. Also the shear capacity of members under axial loading is discussed for reinforced fibrous concrete columns.

Atheoretical analysis using the computer was made to predict the behavior of the axial load-moment interaction diagram of reinforced fibrous concrete columns. Experimental results from tests using fibers is given. The results will bring out the confinement and ductility capabilities of these members.
