A DESIGN MODEL FOR INTERMEDIATE WEB STIFFENERS.

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 1996
This paper presents a design method, based on strength and stiffness criteria, which takes rational account of the effects of out-of-plane web forces and of the tendency for the stiffened panel to buckle overall. The method is validated by reference to the earlier theoretical and numerical parametric study.

Buckling of Stiffened Webs by Local Edge Loads

Journal of the Structural Division, 1982
A finite strip method is used for analysing the buckling of longitudinally stiffened web plates subjected to transverse local edge loading. The probLem is of particular importance for box girders, which have relatively weak flanges for resisting this type of buckling.

Tests on Strength of Coped Beams with Web Stiffening

Advanced Materials Research, 2010
In steel construction, when beams have to be connected to a girder at the same elevation, beam flanges must often be coped to provide enough clearance for practical joint formation. The presence of a cope in a beam will reduce the strength of the beam in the coped region.

Bonded Web Stiffeners for Steel Bridges

1990
The development of structural adhesives has been led by the aircraft industry and the reason is simple. No other connection technique is capable of meeting the demanding requirements. The same is not true in the construction industry, but bonding nevertheless offers significant advantages.

Longitudinal stiffeners for Girder webs; Their behaviour and design

Journal of Constructional Steel Research, 1986
Abstract This paper describes nineteen tests carried out to study the behaviour of longitudinal stiffeners on web plates subjected to predominant shear loading. By considering stiffeners of various dimensions, the behaviour of inadequate and adequate stiffeners is observed and optimum stiffener proportions are established.

BEHAVIOUR OF A WEB PLATE IN SHEAR WITH AN INTERMEDIATE STIFFENER.

Proceedings of the Institution of Civil Engineers - Structures and Buildings, 1993
The behaviour of a simply supported plate with a single stiffener, subject to in-plane shear forces, is studied using elastic critical buckling analyses and non-linear elasto-plastic finite-element analyses. Particular attention is paid to factors relevant to design of the stiffener. Variations in stiffener rigidity, panel side ratio, panel slenderness,

Fatigue Capacity of Stiffener to Web Frame Connections

Volume 6: Materials Technology; C.C. Mei Symposium on Wave Mechanics and Hydrodynamics; Offshore Measurement and Data Interpretation, 2009
Daewoo Shipbuilding & Marine Engineering Co., Ltd. (DSME), StatoilHydro and DNV established a common project to investigate the reason for the difference between calculated fatigue lives and the in-service experience and to assess the fatigue capacity of stiffener web connections subjected mainly to web frame shear stresses.

Design of transversely stiffened webs of I-beams

Journal of Constructional Steel Research, 1993
Abstract The design rules for webs in shear given in the limit states British and Australian steel standards are reviewed. The semi-analytical complex finite strip method of buckling analysis is then used to obtain the elastic local buckling coefficients of the webs of I-beams subjected to shear when the restraint provided by the flanges is included.

TRANSVERSELY STIFFENED GIRDER WEBS SUBJECTED TO SHEAR LOADING - PART 2 : STIFFENER DESIGN.

Proceedings of the Institution of Civil Engineers, 1990
This paper examines the bases of current design formulations for transverse stiffeners in girder webs and compares these with the results of numerical studies carried out by the Authors. A simple analytical model is then formulated which reproduces the numerical parametric results more consistently.

Numerical investigations on web panels stiffened by one or two trapezoidal stiffeners

2008
This paper focuses on the behaviour of I-girder web panels subjected to combined bending and shear and stiffened by longitudinal trapezoidal stiffeners. This implies to account for the coupling between local panel buckling between stiffeners and global buckling of the whole stiffened panel. The study is restricted to panels with one or two longitudinal
