Lecture 24 – Prestressed Concrete

Lecture 24 – Prestressed Concrete Prestressed concrete refers to concrete that has applied stresses induced into the member. Typically, wires or “tendons” are stretched and then blocked at the ends creating compressive stresses throughout the member’s entire cross-section. Most Prestressed concrete is precast in a plant.Lecture 3 –Precast Concrete in Building - Trent Global,Lecture 3 –Precast Concrete in Building Precast Concrete •Concrete elements, cast and cured in a manufacturing plant, then transported to the construction site.
