16" Deep, 4'-0" Wide Precast Double Tees
16" Deep, 4'-0" Wide Precast Double Tees
(OP)
I recently performed a site visit on a project and found 16" deep, 4'-0" wide double tees for a roof structure. I contacted PCI and they informed me that they do not have any load tables for older 16" double tees. I found load tables for both the 14" deep, 4'-0" wide and 16" deep and 6'-0" wide, but I can't find them for the member size I need. A cantilever portion of the tee was removed and the tee has (8) 7-wire strands and we believe them to be draped. If anyone knows where I can find the correct load tables for these members let me know. This will help verify their capacity. I am currently performing hand calcs for the members but it requires me to make a lot of assumptions regarding the prestressing. I found a similar project, which specifies the same size double tees dated 1971 but I only have the contract drawings and not the shop drawings so I know this is not the only building with these members. The project in located in New Jersey.

Does anyone know where I can get load tables for this old section?
I plan to use H20 loading.
Thanks in advance.

My main concern regarding your question is what seems to be the use of a precast beam as a continuous one of half the span. This might bring (or not) problems depending on how the thing is and as been truly built. Has the original beam been severed in two parts?
