Work Table Leg Design
Work Table Leg Design
(OP)
Hi,
I'm trying to design a work table for our shop using 4x4x1/2" and 5x5x3/8" HSS members for legs. The legs are to be adjustable in height with the smaller HSS "nesting" in the larger. The table height is to be adjusted using the nested HSS and inserting a pin through the two members.
I think I have a handle on the shear stresses in the pins but when considering the compressive stress at the pin holes, would it be too conservative to assume the stress is concentrated over a area equal to the diameter of the hole times the material thickness? ie d x t ?
Any suggestions on how to treat this ananlysis would be appreciated.

If you are using the AISC Manual, you will find this information in section J.7 of the 9th edition ASD Manual or in J8 or the 3rd edition LRFD Manual. The AISC is a structural code used for buildings and some bridges. If you are under a different code, then of course you'll need to find the proper location and be sure to follow its requirements.

I just finished the calculation and it leaves me with a S.F. of 5.02 based on the 5x5x3/8" HSS.
