Ductility of r.c. beams reinforced with FRC

2004
Aim of the present paper is the evaluation of the effectiveness of strengthening interventions with fiber reinforced concrete (FRC), with particular reference to the ductile behavior. As a matter of fact rehabilitation intervention with a material working in tension, but with brittle behavior, cannot be effective for the plastic capacity of the ...

On the Post-Peak Ductility of Shear-Critical Beams

SP-237: Finite Element Analysis of Reinforced Concrete Structures, 2006
This paper describes how code procedures for the seismic design of reinforced concrete structures are increasingly incorporating performance-based criteria. The push-over analyses is being incorporated into these criteria and becoming an accepted means of demonstrating sufficient energy-absorbing capacity.

Plastic Failure of Ductile Beams Loaded Dynamically

Journal of Engineering for Industry, 1976
It is shown herein how simple rigid-plastic methods may be used to predict the large inelastic deformations of fully clamped beams loaded impulsively, and to estimate the threshold velocities at which failure due to either tensile tearing or shearing occurs at the supports of beams.

Failure analysis of blast loaded ductile beam

2009
A failure analysis procedure based on the elastic-plastic finite element analysis of the higher order beam is presented to predict the mode II and III failure of impulsively loaded ductile clamped beams. The variational equation of motion of the problem is first obtained by using the principle of virtual work and the Total Lagrangian Approach together ...

Flexural strength and ductility improvement of NSC beams

2012
In order to calculate the flexural strength of normal-strength concrete (NSC) beams, the nonlinear actual concrete stress distribution within the compression zone is normally replaced by an equivalent rectangular stress block, with two coefficients of α and β to regulate the intensity and depth of the equivalent stress respectively.

Rotational ductility of R.C. beams: a parametric analysis

2006
The evaluation of plastic rotation capacity in reinforced concrete beams is essential to prevent brittle failures. In order to facilitate practical applications, the methods usually adopted in International Codes (see EC2, MC90 or DIN), provide approximate functions θpl vs (x/d)u,conv in which the following principal parameters appear: (i) ultimate ...
