Objetivos

The students attending this course already have some
knowledge and skills in the field of steel and composite
structures. The intention now is to deepen and extend their
knowledge to the areas not already covered in the course,
and to acquire skills to fully undertake projects of steel and
composite structures.

Resultados de aprendizagem e competências

The training will focus particularly on the security check of
the Class 4 cross sections, namely the shear instability of the web and its resistance to transverse loads, the efforts
interaction in the cross section and also along the beams,
columns and beam column. We shall study the elastic global
analysis frames with semi-rigid connections and plastic global analysis. Regarding composite structures intended to address the security check of slabs and beams and composite steel concrete composite joints.

partial connection and their influence over the actuating
efforts, resistant efforts and deformations. Composite
columns. Resistance to axial and flexural actions and shear.
Composite slabs. Profiled sheets and connection. Flexural and
shear. Behaviour in constructive phase and service.
Constructive placement for all elements listed.

connections. Column bases. Connections of triangulated
structures

Métodos de ensino e atividades de aprendizagem

It is available in moodle the syllabus of the course, the lesson
plan of the semester, test type, a set of practice exercises,
and material support. In the first two weeks of class are
constituted working groups which will be provided the
statement of work. In the week prior to the class, is inserted
into moodle, slides of theoretical and practical content to be
worked. In class the slideshow, summarized, exposing the
matter properly structured and conclusions of the class, along
with schematics, diagrams and photos presented, is
undoubtedly a good learning process. It's overrated because
this material is available to students in advance. In practical
classes we do exercises and explain other ones solved
problems of the exercises book and we support the work of
the semester. It is intended that the working group has some
autonomy, try by itself solve emerging problems. However,
the electronic mentoring will be available to clarify doubts
and to support the work, as so the teachers attending
schedule hours.
