A design space representation of stiffened shear webs

The Aeronautical Journal, 1978
A stiffened shear web, consisting of a thin plate (referred to simply as the web) attached to longitudinal members (or flanges) and supported by a series of transverse stiffeners, buckles in a mode involving both the web and stiffeners, at a shear stress which also depends on the restraint between the web and flanges.

Stiffened shear webs: post-buckling failure of stiffeners of less than critical rigidity

The Aeronautical Journal, 1979
The buckling coefficient for a conventional shear web, reinforced by a series of equally-spaced transverse stiffeners, is practically independent of the flexural rigidity of the stiffeners provided this exceeds a certain critical value. The stiffeners then provide conditions close to simple-support (if they are of negligible torsional stiffness).

Intermediate Web Stiffener Spacing Evaluation for Shear Links

Journal of Structural Engineering, 2019
AbstractEccentrically braced frames (EBFs) are a widely used steel seismic resisting system due to their combination of high elastic stiffness and high ductility.

Stiffening Effect of Motor Core Webs for Torsional Rotordynamics

Volume 7: Structures and Dynamics, Parts A and B, 2012
Longitudinal webs or spider bars are often placed mid-span of a motor shaft and are primarily used to support the windings or rotor laminations while allowing sufficient space for cooling air flow. When subject to a torque, the radial webs experience a loading configuration that includes bending and torsion while the base shaft experiences pure torsion.

Design of web stiffeners: local panel bending effects

Journal of Constructional Steel Research, 2004
Abstract Existing design methods for web stiffeners differ widely in concept and in the stiffener size which results. An investigation was conducted to provide a rational, usable and validated design method for transverse stiffeners. The proposed design method takes account of the axial compression in stiffeners caused by tension field action (J ...

On the torsional stiffness of closed-section web stiffeners

International Journal of Mechanical Sciences, 1965
Abstract The restraint against buckling provided by the torsional stiffness of closed-section web stiffeners is examined. It is shown that the resistance to rotation of the edges of the panels is appreciably affected by the flexibility of the section in its own plane, and that the wavelength of the buckling mode affects this reduction in stiffness ...

Behaviour of Stiffened Web Plates Subjected to the Patch Load

1992
This paper gives results of numerical analysis on the web plates subjected to a patch load having a horizontal stiffener. The Dynamic Relaxation Method is used for the numerical method. Patch length and the support condition of upper edges of web plates are adopted as parameters, and relatively larger patch length is used.

Influence of Stiffener Thickness and Rivet Position upon the Effectiveness of Single-Sided Stiffeners on Shear Webs

Aeronautical Quarterly, 1964
SummaryThe paper presents the results of an experimental study of the buckling of transversely stiffened shear webs when the stiffeners have a thickness less than that of the web-plate.It is shown that the effectiveness of such stiffeners is greatly influenced by two factors, the ratio of the thickness of the attached leg to that of the web-plate and ...
