Final Design
- Determine loading
- Calculate post-tensioning force using load balancing and verify minimum pre-compression level
- Calculate member moments due to gravity loads
- Compute secondary moments
- Calculate moment redistribution
- Check service stresses
- Calculate minimum non-pre-stressed reinforcement (Un-bonded system) & Calculate temperature and shrinkage reinforcement
- Check ultimate strength and supplement with non-pre-stressed reinforcement, if required
- Check punching shear if required • Check deflection
- Construction documents
- Prepare framing plans showing post-tensioning layout, final effective forces, and profiles
- Show non-pre-stressed reinforcement layout on the framing plans • Provide details at openings, re-entrant corners.
