Objetivos
The main objective is to initiate students to the study of Structural Dynamics. Earthquake Engineering problems are studied based on previous knowledge. Basics of Seismic Engineering are revised in seismic structural response context. At the end of the course students will acquire the ability to perform seismic analysis of structures in the context of Eurocode 8.

Métodos de ensino e atividades de aprendizagem
Overall exposure of materials using presentations (with animations and images) in Power-Point. Presentation of practical examples. Self-learning of theoretical and practical proposed problems. Use of computer programs for dynamic analysis of structures. Classes will be held in computer rooms where students use computer programs to solve problems that were previously solved manually. In class-oriented guidance tutorial will discuss the proposed resolutions of problems, with guidance from teachers, but aimed at empowering learning.
