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

Structural mechanics: basic principles of static solution - simple supported and continuous girders, truss structures. Metal structures - design of members and connections of steel structures. Concrete structures - basic principles of design of concrete structures.

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

It is possible to study optional courses from the given study programme exceeding the scope of the study plan.

Not applicable.

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

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