Analysis of Structures II C


The curricular unit complements Structural Analysis I (SAI) in theory of plates and introduces basic concepts of dynamics of structures.

By completing the CU the students should be able to:

Apply the grillage methods  to calculate plate bending problems.

Familiarize the students with computer modeling and illustrates the application of the appropriate methods for modeling plates.

Identify the parameters that control the structural dynamic response, acquire "engineering judgment" based on evaluation of basic characteristics of loading and of the resisting system.

Educates the student to interpret results obtained computationally and educates their "engineering judgment" when doing so.

Teaching method

The hours of contact will alternate between theoretical and practical topics, taking into account the complexity of the theoretical concepts. During the classes, theoretical subjects and reference problems are presented and discussed. Each topic presented is followed by the resolution of a larger set of problems involving a reduced complexity that can be manually solved, to give a more practical insight about theoretical concepts and encourage the students'''''''''''''''' initiative and their active participation. In this sense the students in a group of 2 or 3 are helped to carry out the assigned work, consisting in resolution of structural analysis problems. The consultation of bibliography and of the handouts available online via CLIP are encouraged. Individual study outside of the class attendance is stimulated and reflective thoughts on the structural functioning exercised. Analysis and problem-solving skills are assessed continuously during the classes and through unseen written examinations.
