Design of web stiffeners: axial forces
Journal of Constructional Steel Research, 2003Abstract Existing design methods for web stiffeners differ widely in concept and in the stiffener size which results. This paper describes part of an investigation which aims to provide a rational, usable and validated design method for transverse stiffeners.

Compression tests and numerical analysis of web-stiffened channels with complex edge stiffeners
Journal of Constructional Steel Research, 2016Abstract The paper describes a series of pin-ended compression tests and numerical analysis of channels with complex edge stiffeners and two different types of web stiffeners. In the tests, axial compression and eccentric compression loading were imposed respectively on 18 and 12 specimens.

A parametric study on the longitudinal stiffeners of web panels
Thin-Walled Structures, 2008Optimum location and dimensions of longitudinal stiffeners in web plates under in-plane bending are investigated. This parametric study is performed by numerical simulation utilizing finite element method. Several plates having various aspect ratios are analyzed and an equation for minimum required second moment of area of stiffeners is presented and ...

Advances in Structural Engineering, 2015
In order to study the influence of web holes on axial compression behaviors of thin-walled columns with different section forms, a total of 10 pin-ended compression specimens with two section forms were tested. One section is channels with complex edge stiffeners and web holes, the other section is channels with complex edge stiffeners and Σ type web ...

Thin-Walled Structures, 2020
Abstract Cold-formed steel (CFS) channel beams are an increasingly popular choice as load-carrying members in building structures. Such channel beams often include web holes for installation of services. Traditional web holes are normally punched and are un-stiffened. This can restrict the size and spacing of web holes.

Web-Stiffened Sandwich Structures
Journal of Applied Mechanics, 1971A model representation of a web-cored sandwich structure, which is based upon the energy principles of continuum theory while retaining the discrete nature of the webs, is studied. The determination of a second-order shear modulus, which measures local bending effects, accounts for the transverse shear deformation of the core.

A study of fatigue crack propagation at a web stiffener on a longitudinal stiffener
Journal of Marine Science and Technology, 2010Predicting fatigue crack growth after its detection during in-service inspection is necessary to prevent a loss of serviceability, such as the oil and/or water tightness of critical compartments. This paper focuses on the most typical fatigue cracks that start at the weld joint between a flat bar stiffener on a transverse web frame and the flange of a ...

Torsional Stiffening of I-Girder Webs
Journal of the Structural Division, 1979The torsional response of box stiffened I-sections has been predicted by two analytical procedures. These methods utilize basic torsion theory and compatibility relationships. One method (approximate) is only applicable for L/a≤1.0 The other method (exact) is valid for all ranges of L/a.

Transverse Stiffener Requirements for Curved Webs
Journal of the Structural Division, 1973The buckling strength of cylindrical web panels of horizontally curved girders subject to shear stress is studied analytically. A simplified mathematical model that treats the web as a simply supported curved panel reinforced by transverse stiffeners is used. The solution for this model is obtained by the Galerkin method in conjunction with the Donnell
