Objectives

This course aims to acquaint students with theoretical and practical knowledge in the areas of the conception and sizing of foundations of buildings and works of art, as well as of structures for support and containment of excavated or filled with earth bulks. In the domain of design, it is intended to present the project and workmanship solutions (“sapatas”, props, wells, walls of support, curtains of containment, etc.), as well as in lands (ground, rocks, ground & rocks). Concerning the sizing and security, the basic aspects of the use of the geologic and geotechnical parameters of the bulks will be reviewed, argued its variability, control and concepts of security. The calculation models will be presented and used in the resolution of cases. The interaction between lands and the structures will be discussed based on some cases of design.

Program

Verification of the security. Parameters and geologic variable. Methods of sizing pseudo-statisticians, partial coefficients of security, national regulations of security and euro-codes. Deterministic methods. States limits. Geotechnical and structural sizing of the foundations, interconnection and interferences and sensebilities. Foundations Conception in function of the typology and magnitude of the efforts to transmit to the land. Constructive efficiency and adaptation of the solution to the efforts, processes, required durability, and control of the interference in the structure. Direct foundations and half-deep bulks or, in ground or ground &rocks. “Sapatas”. Sizing. Verification of the security relatively to the capacity of lands and the nestings. Sizing, efforts, codes. Reduction and control of the nestings limits. Durability. Cases and problems to decide: isolated “sapatas”, and “ensoleiramentos”, interference between land and structure. Indirect or deep founndations . Props. Materials. Constructive solutions and technologies. Aims and effects of the use of props. The efficiency and the constructive technology: cravadas props, molded with lost or recoverable mold, props executed with bentonical support of muds. The choice of the solution and the hidro-geologic environment. Geologic Scenes, B, C. Sizing. States limits. Empirical, analytical methods, correlations. Control and assays of reception. Sizing of bulks. Isolated props and in set. Cases of workmanship and conception. Micron-props and jet-grouting. Considered problems: isolated prop, massive of props. Structures of support Impulses active, in rest and liabilities. Fasing of the hollowing or landfill, and mobilization of the impulses. Walls and curtains. Constructive solutions. Curtains of props, molded walls, of metallic profiles, entivation and support for anchorage dues. Diagrams of impulses. The effect of the water and its control. Efficiency and security of the long term drainings. Walls of gravity, walls in L, walls of gabions, verification of the security.
Landfills and recommendations. Curtains for containments. Walls for land support in buildings. Constructive processes. Choice of the solution in face of the constructive procedures and effect on neighbour buildings.

DEMONSTRATION OF THE SYLLABUS COHERENCE WITH THE CURRICULAR UNIT'S OBJECTIVES:

The curricular unit is into the group of curricular units of synthesis from the branch of Structures dealing, as a complement to other curricular units of the study cycle, the fundamental aspects of the buildings and bridges foundations as well as support and containment structures. It is discussed technical and scientific aspects of these subjects that allow students to acquire essential knowledge of this specialization for their professional activity, whether in the project area or in the production area (Work Director, Inspection).

Teaching methods and learning activities

Theoretical and practical classes (exercises based on the themes of the course)

DEMONSTRATION OF THE COHERENCE BETWEEN THE TEACHING METHODOLOGIES AND THE LEARNING OUTCOMES:

Application of knowledge acquired in conception and design of foundations and supporting structures. Develop the fundamental design aspects of foundations, manipulating the various elements of design, with particular emphasis on design elements. Discussion and critical analysis of various solutions for foundations and support structures, framing aspects pertaining to various constraints, technological aspects of construction, time of execution of work and cost/benefit. Manage aspects of the project constraints of support structures, propose and design a solution containing a case study. Evaluate different design solutions supporting structures studied by different groups of students. Identify and critically analyze the advantages and disadvantages of these solutions in the perspective of choosing the most efficient solution.

Eligibility for exams

According to General Evaluation Rules of FEUP
Practical assignments worth a maximum of 5 values, they should be delivered to the professor, who gives the practical classes. They will be later assessed and discussed.

Calculation formula of final grade

A mini-test in November that will worth a maximum of 15 values
The assignments marks will added to the mini-test mark, according to the rules for the Integrated Masters in Civil Engineering. Students have to reach at least 40% of the mini-test mark in the practical assignments.


Assessment components
A - Assessment of exercises (practical classes) (0-3)
B - Assessment of assignments (0-5)
C - Mark of the exam (0-12)

Special assessment (TE, DA, ...)

SPECIAL RULES FOR MOBILITY STUDENTS:
Proficiency in Portuguese and/or English;
Previous attendance of introductory graduate courses in the scientific field addressed in this module;
Evaluation by exam and/or coursework(s) defined in accordance with student profile.

SPECIAL RULES FOR STUDENTS WITH A SPECIAL STATUS:
Students with a special status, such as working students, do not have to make the practical assignments. However, they have to attend the mini-test (20) with the rest of the students. Recurso exam follows the same pattern.

Classification improvement

The Recurso exam will take place at the week between normal and recurso season (2-7 of February), according to according to the rules of the Integrated Masters in Civil Engineering.
