2. Objectives and learning outcomes
The primary aim of the course is to provide the students with basic knowledge on the functional and structural design principles as well as the structural behaviour of bridges and key objects of the infrastructure. During the semester the following topics are discussed: historical development, basic terms and classification of bridges; superstructure systems, typical superstructures of steel, steel and concrete composite as well as concrete bridges; composite action between main girders; basis of bridge design, traffic load models and their application rules for highway and railway bridges; substructures of bridges (abutments and piers), bridge equipment; conceptual design of bridges (fitting of bridges into environment, bridge aesthetics); civil engineering work of traffic infrastructure, water-supply and waste-water systems and hydraulic engineering
2.2 Learning outcomes

- knows the material-dependent superstructure systems, their mayor parts and behaviour,
- knows the particularities of moving loads, the principles of critical load positioning, the traffic load models of bridges and their application rules,
- knows the typical substructure types, their parts and behaviour,

- knows the key objects of traffic infrastructure, water-supply and waste-water systems and hydraulic engineering and the structural aspects of their functioning,
- capable of numerical modelling and analysis for grid-type superstructures,
- capable of defining and positioning of the traffic loads on bridges as well as combining them with other non-traffic actions,
- able to calculate the extremities of internal forces and stresses at given locations of grid-type superstructures,
- able to numerically verify the most important structural requirements of bridges,
- cooperates with the lecturer,
- improves his/her knowledge by consecutive learning activities,
- open to use numerical software,
- makes effort to perform exact and error-free calculations,

D. Autonomy and Responsibility
- capable of modelling grid-type superstructures and performing their preliminary structural analysis without mayor help,
- individually capable of justifying the exactness of new structural solutions and their basic application,
- uses systematized thinking approach.
Lectures, individually performed homework (modelling and verification tasks), written and oral communication, use of IT tools and techniques.

II. Subject requirements
Assessment and evaluation of the learning outcomes
3.1 General rules
The assessment of the learning outcomes specified in clause 2.2. above and the evaluation of student performance occurs via one homework (30 points) during the semester and an oral exam (70 points) at the end of the semester. In total 100 points (100%) are acquirable.
3.2 Assessment methods
|Evaluation form||Abbreviation||Assessed learning outcomes|
|Homework, Midterm#1 (midterm evaluation)||HW1||A.2-A.3; B.1-B.4; C.1-C.3, C.4-C.5; D.1|
|Exam (synthetized evaluation)||E||A.1-A.6; C.1-C.2, C.4-C.5; D.2-D.3|
The dates of deadlines of assignments/homework can be found in the detailed course schedule on the subject’s website.
3.3 Evaluation system
3.4 Requirements and validity of signature
- Attendance on at least 70% of lectures.
- Successful submission of homework (min. 50%).
3.5 Grading system
3.6 Retake and repeat
- The submission deadline for homework is set in the detailed subject requirements.
- The homework not submitted until the submission deadline may be submitted until the retake deadline set in the detailed subject requirements but is subject to payment of repetition fee. No homework submission is alowed after the retake deadline.
