![]() ![]() The decompression stress in the tendon is the increase in tension from the point of effective prestress to the point where the stress in the concrete is zero under increasing load. If the load continues to increase after full decompression then the concrete goes into tension, potentially resulting in cracking. Decompression is simply the loss of that compression (or prestress) due to an increase in the load on a member (on the flexural tension side of the section) back to a concrete stress of zero. You can think of the concrete going from zero stress to an effective (after losses) compressive prestress. With prestressing you are compressing the concrete around the tendon.
