End plate moment connection 1

[Veer007]

Hey Guys,
I just wonder about this one, why generally we have to separate top and bottom bolt groups for endplate connection? what if the bolt has been provided continuously throughout the web of the beam?

I knew that the top group bolts were in tension and bottom one in compression, then what was my concern is

Should not we provide bolt at the center of the web where rounded in red? so that, why?

when I have moment force and shear force, I should count on flange bolts (bolts that near to flange both above and below) for moment and web bolts for shear.

Thanks in advance!!

Veer007,

Plate thickness is by design to satisfy bolt bearing, and flange tension. Note that the tension is considered to be resisted by a tee in a hanger situation, for which prying force needs to be evaluated, that increases strength demand.

Thicker end plates have a big influence on the effects of prying action which influences the residual strength for shear.

Plate thickness is also based on bending of the plate as the effect of the bolt tension migrates from the bolt to the stiffener or flange.
