Requirements for the cover plate of the distribution box beam
Length of a cover plate should be at least twice the beam depth plus 3 ft. The use of cover plates in regions of high moment allows the use of a section of lesser weight and lesser flexural capacity to be used as the primary beam. This may. Composite beam design/check consists of calculating the flexural, axial, and shear forces or stresses at several locations along the length of a member, and then comparing those calculated values with acceptable limits. That compari-son produces a demand/capacity ratio, which typically should not. of structural steel elements for buildings. Wor ed examples are presented where appropriate. The body of the boxes shall have sufficient re- enforcement with suitable size of channels keeping a provision for fixin andle conforming to general.
