The contents relate to the necessary knowledge for understanding the structural behaviour of architecture constructive systems. The basic tools will be dealt with the aim of providing the instruments for the more frequent structural problems control, both in design and critical reading and interpretation. It will be important to establish a link with concrete areas of operation and application
