A Eurocode‐compliant design approach for cold‐formed steel sections
Steel Construction, Volume 16, Issue 2, Page 78-92, May 2023., 2023 Abstract A Eurocode‐compliant design approach was developed for the design of thin‐walled cold‐formed steel sections which combines the AISI S100‐16‐Direct Strength Method (DSM) with the design provisions of EN 1993‐1‐3. The new design approach transfers the cross‐sectional resistance determined acc.

Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 The axial compressive performance of steel‐reinforced concrete columns with monosymmetric cross‐shaped steel (SRCC‐MCS) was investigated in this study. Tests were conducted under pure axial compression to determine the effects of cross‐shaped steel eccentricity ratio, concrete strength, steel ratio, and stirrup spacing on the resulting failure mode ...

Test and Numerical Analysis on Damaged Steel Beam Strengthened with Prestressed CFRP Sheet
Advances in Civil Engineering, Volume 2021, Issue 1, 2021., 2021 This paper presents the experimental and numerical analysis of damaged steel beams strengthened with prestressed CFRP sheet or only strengthened with CFRP sheet. The test results showed that damaged level had a significant effect on the stiffness, yield load, and ultimate bearing capacity.

Advances in Civil Engineering, Volume 2020, Issue 1, 2020., 2020 Concrete‐filled tubular flange girders have been used in bridges, and torsional bracings are widely used in them to increase the lateral‐torsional buckling strength. This article proposes an analytical solution for the lateral‐torsional buckling (LTB) of concrete‐filled tubular flange steel girders with torsional bracing under a concentrated load.

Journal of Engineering, Volume 2020, Issue 1, 2020., 2020 This paper presents the effects of the several factors that influence lateral‐torsional buckling on freestanding circular arches. The studied factors that attribute to the effects of lateral‐torsional buckling include cross section type, included angle, slender ratio, imperfection, loading, and boundary conditions.

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures [PDF]
, 1988 A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in ...

Nonparaxial accelerating Bessel-like beams [PDF]
, 2013 A new class of nonparaxial accelerating optical waves is introduced. These are beams with a Bessel-like profile that are capable of shifting laterally along fairly arbitrary trajectories as the wave propagates in free space.
