BUILDING SCIENCE

Course objectives

Mechanics of Materials and Structures The course provides the theoretical basis of structural engineering by illustrating theoretical models and practical tools for the analysis of structural systems (mainly those composed by beams), and examining their equilibrium, compatibility, strength and stability. The topics dealt with contribute to form the necessary knowledge to identify, formulate and solve the structural problems of architectural design, and to understand the technical language of structural engineering. The expected objective is the learning of methodologies for setting and solving many problems of structural analysis and design.At the end of the course students shall be able to analyze and solve simple structural patterns, such as statically determinate and indeterminate systems of beams and trusses, by evaluating their states of stress and deformation and carrying out the safety check of the cross sections. Moreover they shall know the basics of continuum mechanics. The learning process is verified during the course through exercises and written tests.
