Institute of Metal and Timber Structures (KDK)

Limit states of metal bridges. Material of metal bridges. Loads of bridge structures. Overview of basic structural systems of plated-girder and truss-girder metal bridges: railway bridges - with member bridge deck, with rail-bed bridge deck; road bridges - with member bridge deck, with orthotropic bridge deck, composite steel-concrete bridges. Static design of deck members: member bridge deck - stringers, tranverse girders; rail-bed bridge deck - longitudinal and trensverse stiffnesses. Static design of bridge main girders: plated-girder and truss-girder bridges.

Structural mechanics: static solution - simple and continue girders, truss structures, arches, influence lines. Metal structures: design of elements and connections of steel structures.

Extension of the knowledge in the field of structural mechanics - live load by traffic loading actions, influence lines. Extension of the knowledge in the field of elasticity and plasticity - global analysis of load-carrying systems of metal bridges (elastic and plastic analysis).

The course is taught through lectures, practical classes and self-study assignments. Attendance at lectures is optional, but attendance at classes is compulsory.

For the successful graduation of this course it is necessary to static and structural design of steel plated-girder bridges within the exercises, based on the individual task, with the extend given by the teacher. The attendance in the exercises is compulsory. The exam is realized by the written form and its extend follows the course annotation.
