Learning outcomes

A student gains these knowledge and skills:
Understanding of the monolithic reinforced concrete slabs locally supported. Understanding of the design and specific behaviour of precast concrete structures. Understanding of the behaviour of prestressed concrete structures. Knowledge of design of selected civil engineering structures.

Prerequisites

structural mechanics, theory of elasticity, load, design of concrete members, design of framed and flat concrete structures

Corequisites

do not required

Planned educational 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).

Forms and criteria of assessment

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.

Objective

Understanding of the specific behaviour of precast concrete structures. Design of precast concrete structures.
Understanding of the behaviour of prestressed concrete structures.
Basic principles of design of selected structures for civil engineering together.
