Buckling of high-strength steel beams

, 2020
This thesis presents experimental and numerical studies on the instability of I-section beams fabricated from high-strength steel (HSS) plates having yield stresses greater than 690 MPa. The research program contains three major tests including the assessment of residual stresses in welded I-sections, the buckling of I-beams and the lateral-torsional ...

Minimum Flexural Reinforcement Steel Ratios of High‐Strength Concrete Beams

Advances in Civil Engineering, 2022
Considering that most studies depend on theoretical equations to determine the minimum reinforcement ratio, only a few studies on this ratio are available. Therefore, a more defined limit should be suggested to design codes by performing additional investigations and experimental studies on this limit.

Shear performance of high-strength friction-grip bolted shear connector in prefabricated steel–UHPC composite beams: Finite element modelling and parametric study

Case Studies in Construction Materials, 2023
As a competitive alternative for accelerated bridge construction (ABC), prefabricated steel–ultra-high-performance concrete (UHPC) composite beams containing high-strength friction-grip bolt (HSFGB) shear connectors offer numerous advantages, including ...

Flexural Behavior of Concrete Beams Reinforced with High-Strength Steel

Iraqi Journal of Civil Engineering
Most concrete structures are reinforced with steel bars to enhance their performance. However, engineers face two major challenges: the high cost of steel compared to concrete and congestion of reinforcement, especially in beams and beam-column joints ...

Structural performance of composite beams using advanced modeling for nonlinear analysis

Dyna
A few studies used full-embedded steel sections in composite beams to reduce their cross sections. This paper presents the behavior of normal and high-strength composite beams having various heights of full-embedded steel sections.

Characterization of Defect Distribution in an Additively Manufactured AlSi10Mg as a Function of Processing Parameters and Correlations with Extreme Value Statistics

Advanced Engineering Materials, EarlyView.
Predicting extreme defects in additive manufacturing remains a key challenge limiting its structural reliability. This study proposes a statistical framework that integrates Extreme Value Theory with advanced process indicators to explore defect–process relationships and improve the estimation of critical defect sizes. The approach provides a basis for

Thermomechanical Fatigue and Creep–Fatigue Interaction of Inconel 718 Additively Manufactured by Laser Beam Powder Bed Fusion

Advanced Engineering Materials, EarlyView.
Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

Influence of concrete strength in the minimum shear reinforcement ratio of beams

Revista Ingeniería de Construcción, 2005
Lightly reinforced concrete beams fail in a brittle manner, due to steel fracture soon after cracking of concrete. In order to avoid such a brittle failure and provide certain ductility at failure, codes of practice give formulae for minimum ...

Creating Ti–Fe α/β Alloys by Diffusion‐Driven Solid‐State Processing

Advanced Engineering Materials, EarlyView.
This study proposes making alloys containing fast diffusing elements that are difficult to produce by ingot metallurgy, by diffusion‐driven solid‐state HIP processing of elemental powders and low‐temperature homogenisation. Here, novel Fe‐Ti α–β alloys are formed having fine α–β lamellae, a small β prior grain size without significant intermetallics ...
