WebPT slabs can be designed as self-supporting, which is not practical for RC slabs, and always require backshoring. A gapless pour strip needs to provide for slab shortening and all the structural functionality of a traditional pour strip. It must create ductile reinforcement continuation for both vertical and horizontal load transfer. Web31 Aug 2024 · It was reported that the post-tensioned plate thickness could be reduced by about 14% compared to the conventional transfer plate, and the amount of concrete and reinforcement could be reduced by 13% and 39%, respectively.
