STEEL CONNECTION HELP!

STEEL CONNECTION HELP!

STEEL CONNECTION HELP!

(OP)
hi wondering how much of width of triangular plate takes the compression load from beam above, in corbel style connection
im designing:




how wide is the design strip to take the compression?

and how do i calculate lateral compression length for a triangle like this- kind of laterally supported along its length?

thanks

RE: STEEL CONNECTION HELP!

Probably treat it similar to the bearing on a web format (10t+N) calculations.

A BS5950 book I have says 100mm is reasonable - and picks it out of thin air!

RE: STEEL CONNECTION HELP!

Why so many horizontal bolts? 28? seems a little overkill...

Rather than think climate change and the corona virus as science, think of it as the wrath of God. Feel any better?

RE: STEEL CONNECTION HELP!

The closet similar thing I can think of is the stiffener plate in Bolted Extended End Plate Moment connections (see AISC Design Guide #4).

In that design guide examples, AISC does two checks on the stiffener:
1) Min thickness required for stiffener = thickness of beam web * (Fy_beam / Fy_stiffener)
2) b/t > 0.56*sqrt (E/Fy).... which is, I believe, based on the b/t slenderness limit for the flange of a wide flange under uniform compression.

If you follow those requirements, I believe the stiffener will not be subject to local buckling.
