Shear Strengthening of High-Strength Reinforced Concrete Deep Beams with Openings Using High-Performance Concrete Mortars

International Journal of Concrete Structures and Materials
Reinforced concrete (RC) deep beams often necessitate openings in their web to facilitate building utilities. These openings compromise the shear resistance of the beams and, therefore, should be strengthened in their critical shear zone.

CFRP Strengthening of Steel Beams with Web Openings [PDF]

, 2016
Integration of services via web-openings in steel floor beams is often unavoidable in modern frame buildings. Such web-openings can significantly reduce the shear and bending strength capacity of the beams. Traditionally, the welding of additional steel plates to the opening areas is adopted as a means of strengthening and stiffening.

Flexural Behavior of Steel Beam Strengthening by Prestressing Strands

International Journal of Engineering and Technology, 2018
Seven simply supported steel beams were tested to explain the effect of strengthening by external prestressing strands. All of the beams have the same steel section, clear span length and the strengthening samples which implemented by two external prestressing strands.

Passive Directional Water Transport on Superhydrophobic Gradient Textures Fabricated by Direct Laser Interference Patterning

Advanced Materials Technologies, EarlyView.
Microstructures fabricated by two‐beam DLIP combining spatial‐period and roughness gradients are fabricated to enhance directional transport of water droplets. The coupled gradients increase transport distance by 160% and strongly suppress motion against the gradient, demonstrating an effective strategy for controlled droplet manipulation.
