Objetivos

It is intended that the students acquire basic skills and knowledge in the field of Mechanics of Materials: (i) evaluate stresses, strains and displacements in linear prismatic frame elements under biaxial bending and shear;(ii) evaluate the central core and shear centre of cross-sections;(iii) apply material yield criteria to threedimensional problems with compound forces; (iv) evaluate critical axial force of isolated columns and columns in a framework; (v) evaluate bearing load of columns according to EC3.

Métodos de ensino e atividades de aprendizagem

Theoretical lessons (T) are used to expose the new concepts and some straight forward examples are shown, stimulating critical thinking of the students. Practical lessons (P) are used to apply the concepts to increasing complex exercises, some of them solved by the students independently.
