Analysis of Structures IA
Objectives
The course aims to provide the knowledge of fundamental structural analysis methods and to to further develop the students'''' ability to reason, think and to apply them to solve statically indeterminate structures, establishing the basis for the finite element method and of the thin plates using classical methods.
By the completion of this course the students should be able to:
Formulate the flexibility and stiffness matrices of truss, beam and frame elements and of the plate problems.
Perform linear analysis of the reticulated hyperstatic structures (manually) to calculate displacements, reactions and internal stresses subject to various combinations of loading conditions (applied loads, temperature effects or foundation settlement) and to build compatible and statically admissible solutions in slabs.
Understand how the principles of virtual work relate to the force and direct stiffness method of structural analysis.
Model a structure with elastic supports, inclined supports, or member end releases (hinges).
Develop the ability to make engineering judgment about structural behaviors.

Teaching method
The teaching methods are based on studentcentered teaching approach, theoretical practical
classes and continuos evaluation process.
The theoreticalpractical clasees introduce the fundamental concepts of the curricular unit related to each topic followed by simple practical example, complemented b solving a larger set of problems involving a reduced complexity that can be manually solved. The further objective of the working classes to give a more practical insight about theoretical concepts and encourage the students'''' initiative and their active participation. Individual work, outside of the presencial classes, will be stimulated, by the resolution of a set problems.
Analysis and problemsolving skills are assessed continuously during the practical classes and through unseen written examinations.
Evaluation method
Assessment Method (20192020)
(em construção)
The assessment methods of the course are in accordance with the current Assessment Regulations.
Analysis and problemsolving skills are assessed continuously during the classes and through three unseen written examinations corresponding to the three modules of the curricular unit.
1. Theoretical and practical evaluation:
For the theoretical and practical evaluation the subject matter will be divided into three parts (parts A, B and C). The different parts correspond, as a rule, to the logical division of the taught subject.

Test 1 (NA – 6.5 val)  (aprox. 1.5 hours): Part A: Force Method and symmetry

Test 2 (NB – 7.0 val)  (aprox. 1.5 hours): Part B: Displacment Method and symmetry

Test 3 (NC – 6.5 val)  (aprox. 1.5 hours) : Part C:  Theory of plates
The MTP grade of the summative assessment will be obtained on written resolution of various problems during the class, the attendance of students and the appreciation of the teacher.
MTP = NAP x NATP
The NAP assessment will consist of the classification of the resolutions of the chosen problems and the appreciation of the teacher.
The NATP assessment will consist of student attendance and teacher appreciation.
The frequency will be obtained in accordance with Article 6 of the Evaluation Regulation. To obtain frequency you need to have:
attendance in at least 2/3 of classes
Frequency waiver will be granted in regulated special cases (TE, AAC, DA, etc.).
4. Época Normal
NE = NA + NB + NC ≥ 7.5 ( scale 0 a 20)
5. Época de Recurso
Exame de Recurso: NE ≥ 7.5 (scale 0 a 20)
6. Classificação Final
NFinal = 0.85xNE + 0.15xMTP ≥ 9.5
Students who have special regulated status (TE, AAC, DA, etc.) must take a test to obtain the MTP summative grade on a scheduled date.
Students with a final grade higher than 16 will have to take an oral exam to confirm the grade. In this case, the student''''s classification will be the oral exam classification. If not, the final grade will be 16 values.
Registration for continuous assessment tests is required, otherwise the rules of Article 5 (10) of the current assessment rules apply.
