Neural network‐based models versus empirical models for the prediction of axial load‐carrying capacities of FRP‐reinforced circular concrete columns

Structural Concrete, Volume 25, Issue 2, Page 1148-1164, April 2024.
Abstract This study presents new neural‐network (NN)‐based models to predict the axial load‐carrying capacities of fiber‐reinforced polymer (FRP) bar reinforced‐concrete (RC) circular columns. A database of FRP‐reinforced concrete (RC) circular columns having outside diameter and height ranged between 160–305 and 640–2500 mm, respectively was ...

Study on bending failure and crack characteristics in ductile fiber‐reinforced concrete beams

Structural Concrete, Volume 25, Issue 2, Page 916-934, April 2024.
Abstract In this study, we designed six polypropylene fiber‐reinforced concrete (PP‐FRC) beams and three reinforced concrete (RC) beams for experimental studies. Then, we analyzed the effects of incorporating PP fibers on the cracking performance of PP‐FRC beams from the perspectives of load‐displacement response, crack distribution, crack depth, crack

Improvement of Composite Beam with Web Opening Using Posttensioning Tendons under Static and Cyclic Loadings

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
In practice, the passage of service utilities through web opening causes a significant load‐carrying capacity loss and introduces a change of failure mode of the composite beam. This study aims to improve the load‐carrying capacity and stiffness of open‐web composite beams subjected to static and cyclic loading using posttensioning tendons.
