Numerical Study on FRP Wrapped Concrete Columns Under Compression


Fiber Reinforced Plastic (FRP) wrapped concrete column shows better performance in terms of strength and ductility of the columns. Objective: Already published experimental results of the FRP wrapped concrete columns were used to analyse the same using Finite Element Software ANSYS and ANN. The comparison between the ANSYS and ANN results were made. Methods/Analysis: The cross sections of the concrete column varied in the study were square, circular and rectangular with different corner radius. The software stimulates the behaviour of the FRP wrapped concrete column properly if proper choice of elements from the ANSYS library were made. Findings: Results from the analysis of the specimens made from the quarter part of the model showed that confinement of the FRP over the concrete columns increases the strength and ductility by 25% when compared to unconfined columns. Applications: Anartificial Neural Networks (ANNs) approach was also used to find the compressive stress of the confined and unconfined columns by using both experimental and analytical results.
