Behavior of Repairing Composite I-Section Beams with Opening under Ultimate Torque
Engineering, 2018 An experimental study was conducted to investigate the behavior of composite concrete beams damaged and cracked under pure torsion, and then repaired by external strengthening. This was achieved using high strength Carbon Fiber Reinforced Polymer (CFRP) laminates bonded with epoxy four composite modify reactive powder concrete (MRPC) I-beams. Different

Prediction of Ultimate Torque of Reinforced Concrete Box Beam Bonded with CFRP Strips
KSCE Journal of Civil Engineering, 2018 One control and three strengthened Reinforced Concrete (RC) beams with box-section were subjected to pure torsion. The proposed strengthening schemes were U-jacketing or U-jacketing with longitudinal strips of fiber-reinforced polymer (CFRP). The U-jacketing strips exhibited a reasonable improvement to the ultimate torque from the experimental ...

EFFECT OF PRELOAD TORQUE ON THE ULTIMATE TENSILE STRENGTH OF IMPLANT PROSTHETIC RETAINING SCREWS
Implant Dentistry, 1994 The preload concept proposes that an optimal torque exists to which implant prosthetic retaining screws should be tightened. According to this theory, the preload prevents separation of implant components, thus protecting the screw from fracture. Recent research suggests that most implant-retained prostheses in function today were placed using improper

Strengthening of Ferrocement Beams in Torsion by CFRP Strips [PDF]
Engineering and Technology Journal, 2014 Torsion is resisted well by closed form reinforcement, due to the circulatory nature of the torsion inducing shear flow stresses in a beam. Therefore, it will be more efficient to have strengthening schemes, which are wrapped in closed form around the ...

Tikrit Journal of Engineering Sciences, 2022 The presence of the openings negatively effects on the strength of the beams where they act as a weak point because of the sudden change in the cross-section of the beam, so it becomes necessary to make strengthening for the beams to resist the effect ...
