Lateral-torsional buckling of high strength steel beams: Experimental resistance

Thin-Walled Structures, 2021
Abstract EN 1993-1-1 gives stability design rules for columns, beams and beam–columns up to S460, whereas EN 1993-1-12 gives additional guidance for S500 up to S700. Recent studies show that high strength steel members may be designed using improved buckling curves, where the enhanced behaviour is usually attributed to the improved material ...

Flexural Performance of Composite Beams Using High-Strength Steel and High-Strength Concrete

International Journal of Steel Structures, 2021
The composite beams having high-strength steel (HSS) and high-strength concrete (HSC) can fully exploit the mechanical behavior of both materials. However, the published research on the structural behavior of composite beams using HSS and HSC is limited.

Buckling of welded high-strength steel I-beams

Journal of Constructional Steel Research, 2020
Abstract National constructional steel design standards preclude many high-strength quenched and tempered steel grades, and with the growth update of such steels in structural applications, revision or new guidance is needed. This paper reports experiments and presents numerical studies of welded high-strength steel (HSS) I-section beams fabricated ...

Research on high‐performance steel structure with high‐strength steel column, ordinary‐strength steel beam, and low‐yield‐point steel BRB

ce/papers, 2023
AbstractIn order to reasonably make full use of the advantages of different steels and then achieve a steel structure with excellent seismic behaviour, the authors proposed novel triple grades hybrid high‐performance steel structures (TGHSSs) comprising high‐strength steel (HSS) columns, ordinary‐strength steel beams, and low‐yield‐point (LYP) steel ...

Flexural-torsional buckling of high-strength steel beams

Journal of Constructional Steel Research, 2016
Abstract High-strength steel (HSS) is gaining widespread acceptance in contemporary engineering structures, with grades of up to 690 MPa being included in many design standards. However, although strength grades well in excess of 690 MPa are possible with modern metallurgical processes, these are not compliant with most design codes of practice.

High-Strength Fiber-Reinforced Concrete Beam-Columns with High-Strength Steel

ACI Structural Journal, 2016
A series of reinforced concrete (RC) components with high-strength materials were tested under pure flexural monotonic and cyclic quasi-static loading protocols. The specimen materials included high-strength concrete (HSC), ultra-high-strength steel (UHSS), and steel fibers to create high-strength fiber-reinforced concrete (HSFRC) specimens.

Design of Ultra-High Strength Sheet Steel Beams

SAE Technical Paper Series, 1990
<div class="htmlview paragraph">Cold-rolled sheet steels with yield strengths from 50 to 180 ksi have been used for bumper reinforcement beams. As yield strength increases, thickness can be decreased. However, at reduced sheet thickness, the maximum load capacity of a given beam is influenced by local buckling.

Cyclic Behavior of High Strength Steel H-Shaped Beam

Applied Mechanics and Materials, 2012
This study is intended to show possibility of using high strength steel for H-shaped beams with large depth-thickness ratio in the elastic range by conducting loading tests. Test specimens are manufactured with high strength steel of over 700N/mm2 yield stress. Elastic behaviors of such beams under cyclic loading are mainly concerned.

Development of Low Carbon High Strength H-Beam Steel

Advanced Materials Research, 2010
The application of vanadium-nitrogen alloy to develop a certain low carbon high strength H-beam steel was determined through the combination of theoretical study, product requirements and existing practical conditions. The specific rolling process was further defined through laboratory experiments.
