Base Knowledge
It is intended that students have knowledge about the stability of structures subjected to bending stresses. Know how to calculate tangential stresses (shear stress) due the bending. And calculate efforts and stresses due to oblique bending, eccentric loading, composite bending in three-dimensional structures.
Teaching Methodologies
In theoretical classes, a theoretical exposition of each subject is made, which is complemented by the presentation of application exercises. Theoretical-practical classes mainly focus on solving exercises.
Learning Results
The objective of this course is to provide students with practical and simple methods for calculating the most common typical elements in structures, using several approximate calculation processes.
This U. C. allow students to obtain displacement in structures subject to flexion as well as select the normalized I profile. It gives knowledge of oblique flexion, eccentric load, deflected flexion. Know how to analyze three-dimensional and buckling structures

Continuous Assessment - AC
Continuous Assessment, where 2 frequencies will be held with weights of 50% each.
Frequencies are carried out: the 1st roughly in the middle of the 2nd semester and the 2nd frequency in the week of thermal classes of the 2nd Semester. There are no minimums in the frequencies. For those who are approved during the frequency period, the UC is completed and does not need to come to the exam. Students who have continuous assessment have access to the Normal season.
And for those who are not approved in the continuous assessment, they will have access to the exam season.
