Objectives

This curricular unit aims to provide detailed information and training on prefabricated systems and products. Special attention is paid to the conception, design, transport and erection of precast products, and to the connections between precast concrete elements.
In addition, each student can deepen the study of a specific aspect of prefabrication in concrete, of interest in the context of the research to be carried out in its PhD.

Learning outcomes and competences

Students will get to know the prefabricated products with the greatest importance, with application in the construction of buildings and bridges. They will acquire skills in analyzing and designing specific aspects of prefabrication. They will be able to identify and describe the different types of products used in the construction of buildings and bridges. They will also learn about transport, fabrication and assembly procedures and connection techniques, new technologies and construction provisions, as well as specific standardization of concrete prefabrication.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

Students must have already attended, at bachelor's and master's level, the curricular units of Strength of Materials, Theory of Structures, Construction Materials and Concrete Structures.

Program

The importance of prefabrication; prefabrication and sustainability; evolution of the techniques of building construction.
Evolution of a construction system: provisional support; concrete of different ages; Creep and shrinkage;
Joints: diversity of solutions; behavioural models; design philosophy; ductility.
Prefabrication in buildings: design; structural systems; slabs and walls as diaphragms; structural integrity and accident actions; Preventing progressive collapse;
Prefabrication of bridge decks: use of I and U beams; Continuity solutions on bridge decks; structural assessment

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:

The syllabus focuses on the various issues indicated in the unit’s objectives. The acquisition of key competencies and skills is stimulated though theoretical presentations and discussions, and also by means of the confrontation with practical problems.

Eligibility for exams

To fulfill the attendance condition, the student cannot miss (without justification) more than 25% of the classes.

Calculation formula of final grade

The final classification is determined based on two evaluation components:
- written test, with a practical and a theoretical part, focusing on the matters covered in the curricular unit's syllabus;
- work, to be presented orally and in written form (in the format of a congress article), on the specific topic to be studied in depth (framed in each student's research topic).

Each of these two evaluation components has a 50% weight in determining the final classification.
