FATBAR Post-Tensioned Anchor System for wind turbine foundations and other demanding engineering applications sustains fatigue loads by ETAG 13 test with ease. The FATBARs are post-tensioned against high dynamic stress and thus protect the foundations from cracking even in harsh conditions. The unique design enables FATBARs to sustain greater fatigue loads, which increases the life span of turbine foundations and thereby the cost efficiency of the entire installation. However, an innovative and solution-oriented approach has led to using FATBARs also for post-tensioning staircases.
Open-mindedness leading to new solutions
Sometimes good solutions are at hand and only waiting for someone to discover them. This is how the story of FATBAR goes as well. When looking for a post-tensioning solution in a customer case, a clever guy working on the construction of a residential multi-story building realized we actually already have the solution in our product range.
When used for staircases, FATBARs are attached to anchor plates with a post-tensioning jack at the top part of the wall element. Together with the reinforcement, this creates a stabilizing structure sustaining high fatigue loads. The system has been innovated and further developed in collaboration with our customer Safe-Con.
The use of FATBAR allows transferring more forces into a slimmer structure, which in turn leads to important material savings of both concrete and reinforcement. Furthermore, the FATBAR and precast concrete elements feature design for disassembly as they can more easily be taken apart at end the end of the lifecycle of a building. This way, in the future the material resources will reassert circular economy. Simply put, increased sustainability and smaller environmental footprint.
