Base Knowledge
It is intended that students understand the actions of combined efforts. Understanding the three-dimensional state of stress. Realize effect in terms of voltages eforços combined flexion and torsion.
It is intended that students understand the actions of combined efforts, the three-dimensional stress state and the effect in terms of combined flexion and torsion.
Teaching Methodologies
In the lectures is made a theoretical each subject that is complemented by the presentation of exercises. Theorial and practical classes are focuses mainly in solving exercises.
There is a laboratory component in which practical problems are solved.
Learning Results
The objective of this course unit is to provide students with simple and practical methods for the calculation of the typical elements of the structures being used for various approximate calculation processes
