Flexural testing provides a rapid and straightforward assessment of fiber-reinforced composites’ performance. In many high-strength composites, flexural strength is higher than compressive strength. A finite-element model was developed to better understand this improvement in load-bearing capability predict the three different carbon-fiber-reinforced polymer composite systems. The validated aga...

The use of composite materials is an effective technique to enhance the capacity of reinforced concrete columns subjected to the seismic loading due to their high tensile strength. In this paper, numerical models are developed in order to predict the experimental behavior of square reinforced concrete columns strengthened by glass fiber reinforced polymer and steel bars and unstrengthened colum...

X-ray inspection of Carbon Fiber Reinforced Polymer (CFRP) is time consuming. With classical reconstruction methods, many projections of the object from different orientations are required to obtain high quality reconstructions of the interior fiber composition. In this work, we propose to reconstruct the interior of the CFRP samples with a Neural Network Filtered Backprojection (NN-FBP) method...

In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...
