2018年8月1日 · Moments acting only in the web plane cause biaxial bending and twisting. Z-beams with constrained tension flanges undergo lateral-distortional buckling.

1999年11月1日 · This paper reports the results of ten biaxial bending tests on unbraced, simply supported, cold-formed steel Z-beams loaded at midspan in planes inclined to the major principal plane. These results and those of six beams loaded in the major principal plane are compared with analytical predictions and with simple design approximations.

We consider a simple supported beam subjected to pure oblique bending, on the interval CD from this beam (Fig. 8.4). The forces P, inclined with an angle α with respect to Gz axis, produce between C and D sections only a bending moment M (without shear force), having a constant distribution on C-D interval.

2025年1月30日 · The review of cold-formed steel (CFS) Z-section beams focuses on various design approaches, including analytical, numerical, and experimental methods. It also analyzes their performance under different loading conditions, highlighting their efficiency in …

2024年12月17日 · The present article considers a bi-directional functionally graded (BDFG) beam on nonlinear elastic foundation to investigate nonlinear free vibration behaviour. A power-law distribution function is considered to describe material gradation in both the longitudinal and transverse directions.

2021年3月23日 · Three types of steel sections were subjected to biaxial bending by applying loads to both main axes and examined by both approaches. The concept of Fisher was also adopted as an approach. This...

2018年8月1日 · This paper presents yield limit interaction relations for biaxially loaded non-sway steel beam-columns with a concentrated torsional moment applied at the bottom end.

2023年8月17日 · The numerical study is conducted on the Zee-shaped member subjected to major, minor, and bi-axial moment. The effect of stress distribution due to combined load on the ultimate strength is examined, which forms the basis for the new design formulation for beam-column using direct strength method.

1999年2月1日 · Using the computational neural network model developed by the writers, a comprehensive parametric study is performed for global optimization of cold-formed steel Z-shape beams based on the AISI spe...
