Description
Objectives
The main goals of this course unit are the acquisition of knowledge on the behaviour of reinforced and pre-stressed concrete structures, in terms of durability and safety regarding ultimate and serviceability limit states, including design, analysis, detailing, and erection of beams, columns and slabs.
Syllabus
Historical context Mechanical behaviour of concrete, steel and reinforced concrete elements - tension and bending. Structural safety concepts (Ultimate and Service limit states) and durability (design prescriptions). Collapse criteria in tension and bending. Concepts of resistance and ductility. Design and detailing of reinforced concrete for tension and bending. Reinforced concrete non linear behaviour and concept of stress resultants redistribution. Sress fields and strut and tie models. Behaviour and design to shear and/or torsion. Detailing. Evaluation/limitation of crack opening and of structure deformability. Introductio of prestress effect. Design criteria. Bending with axial force. Second order effects in slender columns.
Cross Competence Component
For this Course Unit the students critical analysis of the results is a fundamental aspect compelling the students to question them. The solution of problems during the semester develop the team working capacities and as well in the way to present the results, aspect that shall be valued. During the semester the need for the students to look for the bibliography and appropriate calculation tools are encouraged. The transversal skills shall be valued in the order of 20% for the semester work.
Ethical Principles
All members of a group are responsible for the group's work. In any assessment, every students shall honestly disclose any help received and sources used. In an oral assessment, every students shall be able to present and answer questions about the entire assignment and solution.
