Shear Behaviour of RC Beams: A Numerical Study
International Journal of Computational and Experimental Science and Engineering, 2023 A two-dimensional (2D) nonlinear finite element (FE) model created for reinforced concrete (RC) beams is presented in this paper. The FE model was verified in order to perform further parametric studies on RC beams with and without existing steel shear links. The parameters were tension reinforcement ratio, concrete compression strength, and beam size.

EXPERIMENTAL RESULTS OF DAMAGED RC BEAMS [PDF]
Theory and Building Practice, 2021 This article presents the results of an experimental study of damaged reinforced concrete beams. Corrosion of reinforcement in concrete is one of the main problems of durability faced in practice by civil engineers. Particular attention should be paid to the action of an aggressive environment as one of the most common causes of the introduction of ...

The shear behavior of CFRP Strengthened RC beams
Magazine of Civil Engineering, 2020 The primary objective of this paper is to study the effectiveness of using externally applied CFRP composites as a method of shear strengthening. The parameters investigated in this study included CFRP amount and distribution (i.e., sheet versus strips), bonded surface (i.e., web sheet versus U-wrap), and fiber orientation (i.e., 90° fiber direction ...

Slight Truncation Changes in Iron Oxide Nanocubes Strongly Affect Their Magnetic Properties
Advanced Functional Materials, EarlyView.Subtle variations in nanoparticle morphology can lead to significant changes in functional properties. An automated shape‐fitting method captures minor differences in corner truncation between iron oxide nanocubes of similar sizes synthesized under identical conditions, revealing pronounced disparities in their magnetic and hyperthermia behavior ...

Advanced Functional Materials, EarlyView.Oxygen‐tunnel (OT) indium tin oxide (ITO) vertical channel transistors (VCTs) enable reliable, high‐density gain‐cell memory for monolithic 3D integration. A sandwiched SiN/SiO2/SiN OT stack selectively regulates oxygen transport, suppressing parasitic electrode oxidation while stabilizing channel oxygen vacancies, thereby suppressing carrier injection
