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

Investigation of the effect of using NSM method in repairing cracked concrete beams under static torsional loading [PDF]

مهندسی و مدیریت ساخت, 2020
Most concrete cracks are due to incorrect designs and incorrect execution methods. One of the designs that should be done for concrete parts is the design for twisting. The amount of torsion is significant in edge beams or beams that are connected to the

Self-healing of concrete cracks by the release of embedded water repellent agents and corrosion inhibitors to reduce the risk for reinforcement corrosion [PDF]

, 2017
From the worldwide steel production, approximately 50 per cent is required to replace corroded steel [1]. In the case of reinforced concrete structures, corrosion of the reinforcement steel causes crack formation and spalling which leads to ...

Experimental Investigation of Ductility in GFRP RC Beams by Confining the Compression Zone

Advances in Civil Engineering, Volume 2024, Issue 1, 2024.
Nowadays, building structures in corrosive environments requires some considerations. Being lightweight, high tensile strength, and corrosion resistance are the features that make fiber‐reinforced plastic (FRP) bars an alternative component for longitudinal steel reinforcement of concrete.

A PERFORMANCE BASED APPROACH FOR THE SEISMIC ASSESSMENT AND REHABILITATION OF EXISTING RC BUILDINGS [PDF]

, 2015
Using the results of a past experimental project in which a non-ductile, seismically under-designed building was tested pseudo dynamically in its as-built configuration as well as in two conceptually different rehabilitated configurations, a method for a
