Beam flange and web in tension and compression

Compressive resistance of beam web and flange

The design value in compression is calculated with the help of the fundamental beam resistance

Where is:

Mc,Rd

  • The bending resistance of beam (the shear effect may be neglected in the most of cases, therefore Mc,RdMb,Rd)

hb

  • The beam height

tfb

  • The beam flange thickness

Connected beam

Tensile resistance of beam web

The column web resistance in tension for bolted connections may be calculated using expression

Where is:

beff,t,wb

  • The length of equivalent T-stub of end plate for one or more bolt rows

Stiffness

The deformability of column flange in tension and compression is insignificant comparing to the stiffness of other components. Therefore, stiffness of this component is considered as infinity.
