Complex design of girders from advanced concretes

Anotace

The project deals with proposal of girders, particularly bridge ones, whose height is maximally reduced. For their production, newly developed advanced concrete (high performance concrete, concrete with hybrid binders and alkali-activated concrete) is used. Cross section of the girders is optimized according to properties of concrete and with regard to a fatigue load. The fatigue load play significant role for the subtle cross sections and new materials. Within the project, the following prototypes were developed: Prototyp 1: Trámový železobetonový nosník z vysokopevnostního betonu Prototyp 2: Alkalicky aktivovaný kompozit pro trámový železobetonový nosník Prototyp 3: Vysokohodnotný beton pro předpjaté nosníky Prototyp 4: Vysokopevnsotní beton s drátky pro štíhlé železobetonové nosníky profilu I
