Effective Flange Width of Composite Girders in Negative Moment Region

Transportation Research Record: Journal of the Transportation Research Board, 2005
In the analysis and design of steel-concrete composite bridges, stresses and displacements are typically computed on the basis of elementary beam theory by using the effective flange width concept. Currently, the AASHTO load and resistance factor design (LRFD) code specifies the same effective flange width design criteria for both positive moment ...

Effective Flange Width in Torsion

ACI Journal Proceedings, 1971
AN EXPERIMENTAL INVESTIGATION TO STUDY THE EFFECT OF FLANGE WIDTH ON THE TORQUE CAPACITY OF REINFORCED CONCRETE FLANGED BEAMS IS REPORTED. DATA PRESENTED HEREIN INDICATE THAT THE RECENT RECOMMENDATION OF ACI COMMITTEE 438 ON EFFECTIVE FLANGE WIDTH IS VERY MUCH ON THE CONSERVATIVE SIDE. /ACIJP/

Finite strip evaluation of effective flange width of bridge girders

Canadian Journal of Civil Engineering, 1978
Concrete and steel–concrete composite beam-slab type and box-girder bridges are analyzed using the finite strip method, a variation of the powerful finite element method. The results obtained are used to determine the effective width of the compressive flange of the bridge girders.

Revisit of AASHTO Effective Flange-Width Provisions for Box Girders

Journal of Bridge Engineering, 2011
The nonuniform normal stress distribution along the flange of thin-walled flexural members, such as box girders, is recognized as shear lag effects. Effective flange width is widely used to consider shear lag effects in bridge design. The existing provisions for effective flange width in AASHTO LRFD Specifications can be unconservative compared with ...

Effect of Flange Width on Beam Deflections

SP-203: Code Provisions for Deflection Control in Concrete Structures, 2001
Current concrete design codes use an effective stiffness model to calculate the deflections of T-Beams. Based on the effective flange width, an effective moment of inertia, as well as section properties is computed. This effective flange width is limited by a criterion that is not consistent between various codes and which directly affects the computed

State of the art of the effective flange width for composite T-beams

Construction and Building Materials, 2020
Abstract Composite T-beams represent an efficient and economical structural beam element for a wide range of structural applications. A T-beam subjected to a positive bending moment results in part of the slab acting as the flange of the girder and resisting compression.

Effective Width of the Free Flange of the Ship’s Wide Beam with an Axis Bend

Strength of Materials, 2021
The strain-stress state (SSS) of a free flange of a constant width of the typical ship thin-walled beam with a break of an axis of I-section at elastic deformation is analyzed. The beam consists of a tapered part and prismatic parts of different heights, adjoining it.

ANSYS-Based Study in the New Composite Beam for Effective Flange Width

Applied Mechanics and Materials, 2014
Effective flange width’s value of U-section steel-encased concrete composite beam was studied by ANSYS. Based on the static equivalent principle, the general rules of effective flange width changed with load are summarized by finite element analysis and considering the effect of 4 factors: width-span ratio, loading form, concrete thickness, and ...

On the effective width of girder flanges in elastic and elasto-plastic stages

Journal of Constructional Steel Research, 1992
Abstract An analysis of the completeness of inclusion of steel-girder wide flanges in elastic and elasto-plastic stage operation has been carried out. The results obtained on the basis of designs by the finite element method are compared with the data of foreign standards.
