Nonlinear finite element parametric analysis of prestressed steel reinforced concrete beams

Nonlinear Damping Identification in Precast Prestressed Reinforced Concrete Beams

This article presents a damage detection method for prestressed reinforced concrete (PRC) elements based on free vibration tests and nonlinear damping identification. Integrated static and dynamic experiments were carried out on three precast PRC beam specimens. The static loading induced different levels of damage to the beams. At each damage level, impulsive loading was applied to the beams a...

Finite Element Modelling of Steel-concrete Composite Beams Strengthened with Prestressed Cfrp Plate

This paper presents results from Finite Element Modelling (FEM) of steel-concrete composite beams strengthened with prestressed Carbon Fibre Reinforced Polymer (CFRP) plate. For the purpose of this study, three beams were strengthened using prestressed CFRP plate with three different levels of induced prestressing force. The models were developed using ANSYS FE package. The results of an experi...

Finite Element Modeling of Reinforced Concrete Beams Exposed to Fire

Abstract: The practical implementation of performance-based fire safety design of reinforced concrete (RC) structures hinges on the availability of accurate numerical simulation tools for the behavior of RC members exposed to fire. This paper presents a three-dimensional (3D) finite element (FE) model for the accurate prediction of both the thermal and the mechanical behavior of RC beams expose...
