Residual stresses in welded high-strength steel I-Beams
Journal of Constructional Steel Research, 2020Abstract This study investigates a unified residual stress model applicable for welded high-strength steel (HSS) I-beams. In the experimental program, the homogeneous specimens including two prismatic I-beam samples and a web-tapered I-beam fabricated from Australian BISPLATE-80 and BISPLATE-100 steel plates having nominal yield stresses of 690 MPa ...

Flexural behavior of high-strength steel hybrid composite beams
Journal of Constructional Steel Research, 2018Abstract In this study, hybrid utilization of high-strength steel in composite beams was proposed in order to maximize their flexural capacity and full-scale testing was conducted in two phases to investigate their flexural behavior. In fabricating specimens, high-strength steels were utilized for the bottom flange while normal-strength steels were ...

Helically reinforced HSC beams reinforced with high strength steel
International Journal of Materials and Product Technology, 2005This paper considers the strength gain and ductility of high strength reinforced concrete beams under the combined action of shear and bending stresses incorporating high strength tensile and helical reinforcement. The effect on ductility through the application of helical reinforcement located in the compressive region of the beam is highlighted ...

High-strength steel for resilience of beam-through frames
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2017The application of high-strength steel has been limited due to stiffness and ductility issues. In tension-only concentrically braced steel beam-through frames (TOCBBTFs), the frame is designed to remain elastic while concentrating damage on the replaceable braces during rare earthquakes, which makes the structure able to recover quickly.

Behaviour of normal and high-strength castellated steel beams
Proceedings of the Institution of Civil Engineers - Structures and Buildings, 2012This paper investigates the design and behaviour of normal- and high-strength castellated steel beams under distortional buckling. An efficient non-linear three-dimensional finite-element model has been developed for the analysis of the beams. The initial geometric imperfection, residual stresses and material non-linearities of flange and web portions

High-Strength Steel Door-Beam Design and Digital Simulation
Advanced Materials Research, 2014Due to the yield strength σs, tensile strength σb of high-strength steel is much higher than original one, it is applied in making auto’s structure parts to improve the security of passengers and reduce the weight of auto. To make the production of the cold-stamp parts easier, the paper analyzed the structure of a classical part, door-beam, and found ...

High Strength Reinforced Concrete Beams with Exposed Main Steel
IABSE Congress Reports, 2012<p>As part of our longstanding experimental and theoretical works on maintenance and repair of concrete structures, this paper addresses some aspects of the most common repair technique in which, in the course of applying the repair materials, the concrete cover and steel-concrete bond over certain (shear dominated) regions of the damaged simply

Use of High-strength Steel for Simply Supported Beams
Engineering Journal, 1986As stated by AISC, high-strength steels have proven to be economical choices where lighter members, resulting from use of higher allowable stresses, are not penalized because of instability, local buckling, deflection or other similar reasons. The reduction of dead load and associated savings in shipping costs can be significant factors.
