Notice the assumptions required for the post-tensioned design Fig.2: Tributaries used when computing average precompression WebPost-Tensioned Concrete Designers use post-tensioning as a way to reinforce concrete by prestressing it. In prestressed members, compressive stresses are introduced into the concrete to reduce tensile stresses resulting from applied loads including the self weight of the member (dead load). WebIn a building, a cantilever is constructed as an extension of a continuous beam, and in bridges, it is a segment of a cantilever girder. It can be constructed either cast-in-situ or by segmental construction by pre-stressing methods. Cantilever construction allows overhanging structures without additional supports and bracing. new mtr station
