From a static point of view, the structure has a unique slender ratio of 1:44. © BoysPlayNice The structural material used was UHPFRC class C110 / 130 with dispersed steel fibers, which was developed at the Klokner Institute of the Czech Technical University in Prague. The ultra-high performance fiber reinforced concrete (UHPFRC) is a new high-performance cement composite material. Its mechanical properties (compressive strength 120-180 MPa, bending tensile strength approx. 20-40 MPa) and workability allow us to design new constructions of specific parameters and shapes. At the same time, the service life far exceeds similar structures of con
