Objetivos

It is intended that after the attendance of this course unit, students are able to: (i) to understand the behaviour of a steel and composite structures; (ii) to design and to verify the safety of beams, columns, beam-columns and frames of current steel structures; (iii) to design and to verify the safety of composite concrete-steel beams, and; (iv) to design and to verify the safety of joints in steel and composite structural systems.

Resultados de aprendizagem e competências

With the syllabus taught at the chapter "Steel structures" the students acquire the ability to design and to
verify the safety of beams, columns, beam-columns and frames of current steel structures. With the syllabus
taught at the chapter "Composite steel-concrete structures" the students acquire the ability to design and to
verify the safety of composite concrete-steel beams. With the syllabus taught at the chapter "Connections"
the students acquire the ability to design and to verify the safety of joints in steel and composite structural
systems. With the articulation of all program contents taught in the unit course the students acquire the
ability to understand the behaviour of steel and composite structures.

Métodos de ensino e atividades de aprendizagem

In theoretical classes will be taught the theoretical component of the program of the course unit accompanied,
whenever possible, by the resolution of practical cases of
application of the concepts. In practical classes will be
monitoring the students in the resolution of practical work.

Fórmula de cálculo da classificação final

FINAL NOTE:

Continuous evaluation:

NF = 20% (Test1) + 30% (Test2) + 30% (Test3) + 20% (Regular Exercises).
Regular Exercises consist of 4 Practical Exercises carried out in the classroom (4% each) and 1 Practical Exercise via the Moodle platform (4%).

Minimum weighted average test score of 8 values.

Assessment by Exam:
NF = 100% Exam OR 80% Exam + 20% (Regular Exercises) – the best of the two options will be applied.
Minimum exam grade is 8 values.
If the final grade is higher than 16 points, the student must take an oral test.
