WebA Structural Engineers Approach to Differential Vertical Shortening in ... Web(2) Elastic shortening losses Because all tendons will be simultaneously tensioned the elastic shortening of concrete will not affect tendons since it will be taking place at the same time as tensioning and no loss of prestress force will take place. kN L A sl p p 68.9 21 .3 100 0.64 P A E 0. 001188 193000000 = ⋅ = ⋅ ⋅ ∆ ∆ = ⋅ ⋅ ...
WebAs shown in Figure 2, the pre-tension (P) in the tendon differs from the prestressing force (P) applied to the concrete member. In the case of post-tensioning, pre-stressing is directly imposed against the concrete member. The process of elastic shortening is identical to the pre-tensioning method, but the tension force in the tendon is ... Web3 Estimating Total Losses T.L. =ES +CR +SH +RE (Eq. 1) where T.L. = total loss (psi), and other terms are losses due to: ES = elastic shortening CR = creep of concrete SH = …
WebAug 10, 2009 · I will need to read the paper more thoroughly because all that I have been using to calculate "elastic shortening losses" is E, where a larger E will result in less losses and greater compressive stresses at the mid-span of the deck unit. So when considering stresses at release, the lesser the E value the more conservative the answer. Websum of the elastic and inelastic elongation must be =0: Greater is the inelastic shortening, greater is the pretension. The tension can be generated (in an element with fixed end points) by ...
