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-steelbeamssteel 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.

Due to the pandemic situation, classes were totally, or partially, at a distance using a certain platform.
