What is the use of reduction factors in plate girder design?

Buckling of the web due to in-plane bending does not exhaust its capacity; however, the distribution of the compressive bending stress changes in the post-buckling range and the web becomes less efficient. Only part of the compression portion of the web can be assumed effective after buckling. A reduction in the girder moment capacity to account for the web bend buckling can be used, called reduction factors.

How to Calculate Allowable Bending Stress in Compression Flange?

Allowable Bending Stress in Compression Flange calculator uses Reduced allowable bending stress=Allowable bending stress*Plate girder strength reduction factor*Hybrid girder factor to calculate the Reduced allowable bending stress, The Allowable Bending Stress in Compression Flange is defined as the value which should be less than allowable bending stress when the h/t ratio exceed '760/sqrt(Fb)'. Reduced allowable bending stress and is denoted by Fb' symbol.

FAQ

What is Allowable Bending Stress in Compression Flange?
The Allowable Bending Stress in Compression Flange is defined as the value which should be less than allowable bending stress when the h/t ratio exceed '760/sqrt(Fb)' and is represented as Fb'=Fb*Rpg*Re or Reduced allowable bending stress=Allowable bending stress*Plate girder strength reduction factor*Hybrid girder factor. Allowable bending stress is the maximum limit of bending stress on the bearing plate. , Plate girder strength reduction factor accounts for the strength reduction due to elastic web buckling and Hybrid girder factor Re accounts for the strength reduction due to web yielding and is only important in hybrid girder design.
