Development of Conceptual Design of Bridges

Bridge design developed for centuries. Bridges were originally designed on the basis of experience, during the time a lot of additional criteria influencing the design have been involved. The primary role of the design is played by the design engineer, who is responsible for the evaluation of conditions in the location, design of the bridge structural system, of structural details and of the construction process. The opinions on the structural system changed with development of the design methods. On the other hand, the advanced numerical tools are not able to replace the creativity of the designer.
