PetriCal (cement/wood fiber) Roof Deck Design Data
(OP)
We are looking at an older building with cementitious, wood fiber roof deck similar to Tectum. Manufacturer's rep suggests that product is actually PetriCal by Fireproof Products Company (now Cornell Corporation). I am in need of technical design data for this product, particularily diaphragm capacity. Anyone familiar with PetriCal?

Cement-fiber deck was originally supported by thin-walled box purlins spanning between long-span trusses. Box purlins have a continuous longitudinal slot at top to accept a clip anchoring deck. In 1996, original purlins were replaced with HSS members due to severe corrosion resulting from improper dehumidification. I have attached a couple photos to help describe the existing system.
As part of a re-roofing project, the Existing Building Code requires a diaphragm analysis. Since record drawings are not available we field-measured the existing roof structure. During the field visit we discovered that the replacement purlins were not installed according to the 1996 recommendations, and the diaphragm no longer exists (is not properly connected to resist forces). To re-establish the original diaphragm I am looking for deck manufacturer information/specifications to see if product has published diaphragm capacity and if deck can be re-anchored.

The report includes diaphragm shear values. I have additional information from Cornell Corporation that I intend to submit to SlideRuleEra in the future.

rcd445 - do you have the ability to forward the Cornell Corp. data you have?

On an unrelated but very useful subject, rcd445 also provided a Haven-Busch DLH Bar Joist Catalog which is posted in the same area.
