Post-tensioning design in structural engineering involves the calculation and placement of tendons in a concrete structure to achieve the desired strength and stability. The design process involves analyzing the loads and forces that the structure will be subjected to, determining the size and location of the tendons, and calculating the tensioning force required to achieve the desired compressive forces in the concrete. The design also includes the detailing of the tendon anchors, ducts, and sleeves, as well as the selection of appropriate materials. The design is verified and validated through load testing and analysis, and the construction process is closely monitored to ensure that the tendons are installed and tensioned according to the design specifications.
