Finite element analysis on the performance of strengthening concrete structures confined using natural and artificial fibers

Abstract

In India, there is a drastic increase in the rehabilitation and retrofitting of existing structures compared to demolition. In the current paper, the performance of basalt fiber as a strengthening material in concrete structures for retrofitting application is explored using finite element method rather than the costly experimental method. The model is developed using Jhonson cook's model and is compared with the experimental results for its validation. JC model incorporated with master-slave interaction between concrete-binder and fabric -binder have been modelled as shell elements which replicate the actual scenario of tension or compression only. Analytical models have been emerged as a powerful solution for experimenting stress-strain analysis in composites.
