In a monolithic and segmental construction method

UHPFRC beams with hollow box cross-section


Contrary to the monolithic design, for segment construction single building units are prefabricated in the precast concrete factory for later assembly at the construction site. Using joints and prestressing tendons, they are assembled to make a complete building component, as bridge superstructures, pillars, various tower shafts, for example. Besides the general advantages of industrial prefabrication of the segments at the precast concrete factory, it is moreover possible to install the building structures at the construction site within a very short period of time. For the...
