Strength and Ductility of Concrete Beams Reinforced with Carbon FRP and Steel

November 1, 2001
Author(s)
Dat Duthinh, M A. Starnes
Seven concrete beams reinforced internally with steel and externally with carbon fiber-reinforced polymers (FRP) applied after the concrete had cracked were tested under four-point bending. Results show that FRP is very effective for flexural strengthening

Strength of an Interlocking FRP Connection

November 1, 2001
Author(s)
Dat Duthinh, K K. Bajpai
The strength of an interlocking fiber-reinforced polymer (FRP) connection was measured in bending, and in-plane and out-of-plane shear. This connection allows the rapid assembly of FRP panels into houses, and can be used in interlocking mode only, or

Strengthening of Reinforced Concrete Beams with Carbon FRP

Dat Duthinh, M A. Starnes
Seven concrete beams reinforced internally with steel and externally with carbon fiber-reinforced polymer (FRP) laminate applied after the concrete had cracked were tested under four-point bending. Results show that FRP is very effective for flexural

Tensile Strength of an Interlocking Composite Connection

October 1, 2000
Author(s)
Dat Duthinh
Twenty-four tests of an interlocking fiber-reinforced polymer (FRP) connection show that, although the connection is much weaker than the theoretical strength of the panel under the same type of load (in-plane tension transverse to the main reinforcement

Shear Strength of High-Strength Concrete Walls and Deep Beams

Dat Duthinh
In the last 30 years, the compressive strength of concrete that can be produced reliably in the field has more than doubled, from 35 MPa (5000 psi) to 85 MPa (12 000 psi). Strengths as high as 140 MPa (20 000 psi) can be achieved in the laboratory and, on

Buckling of steel gusset plates

Author(s)
Chiara Crosti, Dat Duthinh
As a result of the structural failure of the I-35W bridge in Minneapolis in 2007, FHWA issued guidelines for the load rating of gusset plates and recommended that the capacity of these plates on non-load-path-redundant steel truss bridges be verified. The
