Overhead Theater Loads
Overhead Theater Loads
(OP)
Has anyone every run across design information on overhead theater loads? I've been asked to review if an existing theater steel truss roof system can safely support the installation of new higher capacity head blocks. The existing drawings do not show design loads. The building was built in 1974. Is there any information available on uniform loads to use for overhead support of theater equipment exclusive of catwalks? The rigging report I was given also mentions shock loads.
Thanks,
Thanks,

In addition, there is a separate chapter (39) dealing with theaters. You might try to get a copy to peruse from the library if there is not one in your office.

Thank you for the reference.
Wow! I didn't' expect that kind of weight. The existing trusses are 40LH13 @ 8'-0 cntr's spanning 68' to 75'with a snow load of 27psf. These trusses are already near their allowable uniform loading and won't safely support that much additional weight.
Thanks again,
