ABSTRACT
The steel-concrete composite road bridges are one of the often designed bridge solutions for mid-span road bridges not only in the Czech Republic, but also around the world. However, due to the relatively high purchase price of the superstructure it does rarely win the public tenders, where the legislation still chooses the best solution only according to construction cost and ignores all other sustainability markers. Therefore, the need for the optimization of this type of structures arises significantly on the market. For that, the newly developed optimization tool in the MATLAB programming environment can help the designers and project owners to optimize their structures, or verify the existing design. The tool is described in the paper and the verification shown on the planned bridge structure.
