Answer 1

The correct answer is longs spans.Key Points

Post tensioning is a construction technique that involves the use of high-strength steel strands or cables to reinforce concrete structures.
The suitability of post tensioning depends on various factors such as span length, design requirements, and construction constraints.
Post tensioning allows for longer spans to be achieved without the need for intermediate supports.
This is because the high-strength steel cables can provide the necessary tensile strength to counteract the weight of the structure and any applied loads.
Longer spans can result in more open and flexible interior spaces, which can be beneficial for certain building types such as sports arenas, exhibition halls, and airports.
Post tensioning can also help reduce the overall weight of the structure, which can lead to cost savings in materials and construction.
The use of post tensioning can improve the durability and resilience of concrete structures, as the cables can help prevent cracking and deformation due to temperature changes, shrinkage, and other factors.

Additional Information

End spans refer to the sections of a structure that are adjacent to a support, such as a column or a wall.
- Post tensioning can be used for end spans, but it may not be as necessary as for long spans.
Break spans are sections of a structure that are interrupted by an expansion joint or a construction joint.
- Post tensioning can be used for break spans, but it may require additional design considerations and construction techniques.
Edge spans are sections of a structure that are located at the perimeter, such as a balcony or a cantilevered slab.
- Post tensioning can be used for edge spans, but it may require additional reinforcement to account for wind loads and other lateral forces.
