Post-tensioning concrete introduces active reinforcing proportioned and positioned to directly counteract the stresses imposed in concrete members due to external loading. Experience and repetition lead to efficient designs, but the first step must be a qualitative understanding of the solution process. This SE University presentation provided information on typical member depths, ranges of post-tensioning forces, and two simple design examples. The examples presented the concept of tendon feasible region, load balancing, and equivalent loading applied to the serviceability and ultimate strength requirements of post-tensioned concrete design.
