A blast test of prestressed concrete slabs
in order to definie design acceptance criteria for prestressed concrete elements for nuclear structures.
Blast tests performed on 16-foot by 16-foot by 10 5/8-inch prestressed concrete slabs with three different combinations of reinforcement and prestressing. The level of pre-stressing for all slabs (either 725 psi or 1450 psi) was introduced using post tensioning with grouted tendons. The explosive charge size and standoff were defined to obtain different target levels of support rotations for each slab design. The test results indicate that pre-stressing level may only have a marginal effect on slab flexural response to blast loading and that the actual blast loading response limits would fall between the currently published limits for pre-stressed concrete and conventionally reinforced concrete elements.

How to Draw PT Concrete Slabs.
IIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIIII
The drafters guide to post-tensioned concrete slabs according to Australian standards .
* Definitions :
- PT : A method of pre-stressing reinforced concrete with tendons tensioned when the concrete reaches a specific strength.
- TENDON : An bundle of strands.
- STRANDS : A single wire in a tendon. Think of the chords that make the rope.
- DUCT : The tube in which the tendons fit.
- ANCHORAGE : The end dangle bits on the duct that 'anchor' it all into the concrete. Commonly at one end is the live end anchor and the other the dead end anchor.
* What do the Symbols Mean ?
See attached dwg file.
Live end .
Dead end .
Number of strands .
Live end with pan .
Overhead / soffit .
Coupler .
* The Two Main Systems of Stressing :
1. Mono-Strand System – Strand stressed individually, usually an oval shaped duct with rectangular shaped anchorages. The most common system used for stressing slabs.
2. Multi-Strand System – All strands stressed simultaneously, usually a round duct with square shaped anchorages.
* Engineering PT drawings : What to Draw ?
These are the engineering design drawings produced for costing etc. pre shop drawings stage.
All anchorage locations (live ends, dead ends, couplers etc.).
Size of the strands in the duct.
Number of strands in the duct.
High and low points of duct.
Dimension is taken from slab soffit to underside of duct.
Same PT duct runs can be linked together.
* Shop PT drawings : What to Draw ?
These are the drawings used on site.
All anchorage locations (live ends, dead ends, couplers etc.) .
All PT duct runs.
Size of the strands in each duct.
Number of strands in each duct.
Unique identifying number (per pour) for each PT run.
Dimensions from grids or walls/columns under to all anchorage points.
Dimensions to variations in the duct run. I.e. the duct does not go in a straight line from live end to dead end which are dimensioned.
Soffit of concrete to underside of duct dimensions at 1 metre spacings.
* Drafting Rules of Thumb :
- Avoid placing text over the thick lines.
- Generally anything greater than 6 Dia 12.7 mm or 5 Dia 15.2 mm use the multi-strand system. Anything less use the mono-strand system.
- Double live ends can be used on longer PT runs
In band beams > 30 m approx .
In slabs > 40 m approx .
In distribution or slabs of ground > 50 m approx .
- Minimum set out dimensions :
Between live ends :
300mm min horizontal 100mm min vertical.
Between Dia 12.7 mono-strand tendons:
150mm min horizontal, 100mm min vertical.
Between Dia 15.2 mono-strand tendons:
175mm min horizontal and 125mm min vertical.
- Concrete Cover :
PT at low points to be chaired at a minimum cover of 25mm to avoid concrete popping out.
At high points 20mm cover for the same reason.
- Reinforcing bars clashing with tendons should be re-layered in a different order or noted on plan to be installed after the PT tendon has been installed.
- High points over supports, low points at mid-span.
