stability of picking beam
stability of picking beam
(OP)
i am designing a pick beam we own that i can stamp and file per osha regs. i am using the asme bth-1 2005 spec which mirrors the aisc asd spec except with addditional safety factors. but my question is how do you determine what the L length of the beam is? (we are using 20' btw) but the ends are not restrained against rotation in the normal sense. i am inclined to use the spread length due to the fact that the beam is somewhat restrained as it is loaded (spreader cables are shackled to the ends at the top of the beam and the vertical wire slings are attached to the bottom of the beam.) any comments?
thanks
thanks

There's also a paper by David Ricker available from AISC. It was published in their journal, 4th Quarter 1991.
