Objectives

Analysis and dimensioning determinate structures: beams, trusses and reticulate structures. The determination of internal forces, stresses and deformation allows the validation of the structural system proposed. First determinate structures are treated and then appropriate approaches for the analysis of redundant structures.

Section Design in steel structures using Ultimate Stress and Ultimate Service Criteria are presented using REAPE (Portuguese specification  for the design of steel structues)

 

Learning outcomes and competences

Students will master the analysis fo determinate and redundant structures. This will involve the computation of internal forces, stresses and deformation in the structure. The design and safety check against Ultimate Limite State and Service Limit State of steel structures, using REAPE.

Working method

Presencial

Pre-requirements (prior knowledge) and co-requirements (common knowledge)

The students are requested to have atended two semester courses on Mechanics and stregth of Materials previously to atend this UC.

Eligibility for exams

According to General Evaluation Rules of FEUP

Calculation formula of final grade

The evaluation is based on two exams of equal weight (50% each one):

-one will be held during the November and it will be related with the first part of contents,
-another one to be performed in January exclusively containing the second part of the contents.

In each of these assessments will be a minimum grade of 6.5 values.

The students:

-that have not gotten an average of 10;

-that have obtained a final average of 10, but have not obtained the referred minimum grade (6.5);

-that have missed at least one of the assessments,

may perform the appeal examination (100% weight) that will evaluate all the contents of the CU.

Students with a final classification greater than 17 on the written examination will be subjected to an oral exam.

 

Special assessment (TE, DA, ...)

These kind of evaluation will be obtained with a final exam.

Classification improvement

Students who which to improve their mark are allowed an “appeal Exam”, according to General Evaluation Rules of FEUP.
