This study aims to strengthen reinforced concrete (RC) beams having insufficient shear capacity using Carbon Fibre Reinforced Polymer (CFRP) members and innovative anchorages. An method is also proposed for strengthening in interaction site of adjacent structures. Test results show that the behaviour has been improved with CFRP elements. The nonlinear finite element (FE) method, as well America...

U-shaped thin-walled concrete bridge beams usually suffer the combined actions of flexure, shear and torsion, but no research about the behavior of U-shaped thin-walled RC beams under combined actions has been reported in literature. Three large specimens of U-shaped thin-walled RC beams were tested under different torque–bending moment ratios (T–M ratios) of 1:5, 1:1 and 1:0 to investigate the...

This study looks to propose a hybrid soft computing approach that can be used accurately estimate the shear strength of reinforced concrete (RC) deep beams. Support vector regression (SVR) is integrated with three novel metaheuristic optimization algorithms: African Vultures algorithm (AVOA), particle swarm (PSO), and Harris Hawks (HHO). The proposed models, SVR-AVOA, -PSO, -HHO, are designed c...

The durability of reinforced concrete (RC) structures and infrastructure has been the subject significant attention from engineering research community in recent years, mainly owing to deterioration RC elements due corrosion embedded steel reinforcement. In this context, stainless reinforcement can provide an efficient solution enhance expected lifetime structures, reducing damage carbonation c...

Physics with neutrino beams has played a crucial role in establishing the standard model and its structure, specifically in leading to the discovery of weak neutral currents and of their properties. Currently, while the physics of neutrinos gives us the first evidence of physics beyond the standard model, the use of neutrinos as probes appears to be the only way of accessing subtle details of t...
