Finite Element Model Updating of Reinforced Concrete Beams with Honeycomb Damage

Flexural Strengthening of Deficient Reinforced Concrete Beams with Post-Tensioned Carbon Composites using Finite Element Modelling

The application of external post-tensioned steel bars as an effective way to strengthen an existing bridge has been so far used in many different countries. In recent decades, however, they have been replaced by bars made from Carbon Fiber Reinforced Polymer (CFRP), as a material with high tensile strength and corrosion resistance, to address several concerns with steel bars such as their appli...

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...

study of behavior of reinforced concrete beams with smart rebars using finite element modeling

in this paper the response of cantilevered reinforced concrete (rc) beams with smart rebars under static lateral loading has been numerically studied, using finite element method. the material used in this study is superelasticshape memory alloys (se smas) which contains nickel and titanium elements. the se sma is a unique alloy that has the ability to undergo large deformations and return to t...

DAMAGE IDENTIFICATION OF TRUSSES BY FINITE ELEMENT MODEL UPDATING USING AN ENHANCED LEVENBERG-MARQUARDT ALGORITHM

This paper presents an efficient method for updating the structural finite element model. Model updating is performed through minimizing the difference of recorded acceleration of real damaged structure and hypothetical damaged structure, by updating physical parameters in each phase using iterative process of Levenberg-Marquardt algorithm. This algorithm is based on sensitivity analysis and pr...
