Hi, could anyone with experience in this bth-1-0211 help explain something about the the effective width limit equations: To me equation now says the effective width beff must byh-1-2011 to 4 x the material thickness which has to be less than or equal to be.

The following editions for this book are also available The effective width shall be taken as the smaller of the values calculated below: The provisions in this Standard apply to the design or modification of below-the-hook lifting devices.
It might be clearer in what i’m asking with an example: American Crane can manufacture new equipment or rebuild your existing equipment.

If the plate is stiffened to prevent out of plate buckling equation does not apply. Cranes are useful and important pieces of equipment used in many applications. Misc Below the Hook Equipment. In developing ASME BTH-1 this subject was considered analogous to the stresses in eye-bars or hooks, which were well studied conditions.
I’m willing to accept I may be missing something here, would just appreciate if someone could improve my understanding. Enter your personal account email address to request a password reset: What I can’t understand is the thoery behind the limit state as this basically states that 4 x the material thickness must be equal or less than the width of material either side of the pin-hole. Below the hook equipment American Crane and Equipment Bfh-1-2011 offers custom engineered lifting devices designed to solve numerous handling problems.
Thanks for the reply JStephen, I have looked up the most up to date standard those equations were from BTH-1my apologies. Enter your account email address to request a password bth-1-211 To help answer your own question, and to make us all the smarter for this exchange, see if you can dig up that Duerr, research, and post it here. Surely if I increase the thickness of material it would serve to reduce the chance of out of plane buckling therefore in theory it should be acceptable to reduce the width between the hole and the plate edge?

Link The two equations shown above are intended to prevent out of plane buckling and are based on empirical research by Duerr, I think that first line is intended to say “beff is less than or equal to 4t and is also less than or equal to be”, and similarly for the second line.
