Learning outcomes of the course unit

A student gains these knowledge and skills:
Knowledge of basic principles of design of bridges. Virtue for designing essential types of concrete slab bridges. Virtue for designing essential types of concrete framed bridges. Knowledge and skill in designing bridge substructure. Knowledge and skill in designing bridge accessories.

Prerequisites

design of road and bridges, design of concrete structures, prestressed concrete

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. Education runs in the forms of lectures and trainings. Character of the lectures is based on definition of basic principles, problems and methodology. In the trainings the main subject matters are trained on individually defined projects (examples).

Assesment methods and criteria linked to learning outcomes

To gain the credit, the students should elaborate individually defined design and calculate specified task. The students are obliged to consult the design continuously in the given terms and submit it to the fixed date. The presences in training lessons are checked. An exam consists both of the written part, in which the task is elaborated, and the theoretical part. To pass the exam successfully, both parts should be accomplished.
