RE: Conc. Tilt-up w/ crane loads

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Jason,
All of the crane loads you are concerned about are prescribed in Section 1607.12 of the IBC. It is also in the ASCE 7. You need to exercise caution in transferring the loads to the precast panels due to the nature of the load transfer of crane loads and stress concentrations.

Regards,
Harold Sprague

Can anyone direct me to some design information on the follow:

I have a concrete tilt-up building, inside the building there is going to be
a 10ton crane.  The crane is supported on steel columns.  I need to brace
the crane using the tilt-up panels. I am looking for information that would
help me find the sway forces/moments (for in and out of plane) induced to
the panel by the crane, so I can design my panels.

If some of you could help direct me, I would appreciate it.

Thanks in advance.

Jason
