Pre-Stressed Concrete
A method of construction whereby compression forces are applied to concrete elements with the goal of counteracting the tension that would otherwise occur due to loads.
In reinforced concrete, the pre-stress is commonly introduced by tensioning the steel element which may be in the form of wire, cable, bar, rod, or strands.
