The principle of load (weight) of the Post-Tension floor system
Due to the unique properties of concrete, concrete has high compressive strength but less tensile strength therefore, the concrete structure must be reinforced with the strength of the concrete.
Reinforced concrete structure use reinforcing steel to help concrete get traction.
The Post-Tension floor structure is to increase the tensile strength of the concrete by putting compressive strength on the concrete structure before loading.
The result of the vertical wire curving resulting in a lifting force in the floor structure, allowing the deflection of the floor to be less than the reinforced concrete structure
