Learning Objectives
The goal of the course is to provide basis for the analysis of two-dimensional behaving structures (plates, cylindrical tanks, domes, membranes) and to take advantage of some specific aspects of the calculation of the structures (such as the global structural concept of buildings, the distribution of horizontal loads, the role of structural ductility structural), also in compliance with the most recent Italian and European regulations.
LEARNING RESULTS
Knowledge and understanding
At the end of the course, the student must have acquired:
- knowledge regarding the modeling and analysis of predominantly two-dimensional structures;
- knowledge of some specific aspects related to the design of the structures.
Applying knowledge and understanding
At the end of the course, the student must have acquired:
- ability to integrate knowledge in the context of structural design;
- ability to use numerical modeling software;
- ability to apply methods and design criteria to a structure.
Making judgments
At the end of the course, the student must have acquired the autonomous capacity of:
- presenting and comparing different models and tools for assessing the structural behavior of some structural typologies;
- identifying and defining proper indicators and descriptors to evaluate data and results;
- identifying possible and potential connections between the various aspects of a topic and / or a problem.
Communication skills
At the end of the course, the student must have acquired the ability to:
- collaborate within a working group, defining objectives, activities, tools;
- present project documents in written and oral form;
- expose the information learned in the course in a clear and proper way.
Learning skills
At the end of the course, the student must have acquired the ability to:
- reflect autonomously on the knowledge and skills of his/her training path;
- identify the possibility of autonomous development of further knowledge, skills and competences.
Prerequisites
Knowledge and skills acquired in Structural Mechanics and Structural Design, normally provided in the Bachelor's degree course, are necessary and sufficient. No prerequisites within the Master's degree program are required.
Learning assessment will take place through two phases, represented by: 1) a small design activity; 2) an oral test.
First phase: design activity
In the first phase, the candidate is asked to carry out, during the course, a small project activity related to a structure. The activity can be conducted either individually or in groups of up to two students.
The activity consists of designing or verifying a simple structure, chosen by the candidate, which must necessarily contain two-dimensional structural elements (for example tanks, domes, shells), preferably in reinforced concrete. In a first part, the analysis of the structure under elementary loads and actions is carried out, by using analytical and / or approximate methods; in a second part, the same structure will be numerically modeled via FEM and the numerical model will be validated by comparing the results with those obtained by the previous approximate solution; in a third phase, once the design actions related to the geographical position of the structure will be included into the model (excluding seismic actions), the stress analysis under the design load combinations will be performed; in a fourth and final phase the general design/verification of the structure will be carried out, and the results will be represented in a graphic form.
The final report (consisting of the written text and the drawings, in the format chosen by the candidate) must be brought with you at the time of the oral exam.
The objective of this first phase is to achieve the ability to develop an engineering analysis of the problem and then to perform an engineering design activity.
Second phase: oral test
The second phase consists of an oral test, in which the candidates will describe documents and drawings related to their exercise; the oral exam will end with theoretical questions, short exercises, critical discussions with the teacher, with the aim of verifying:
- the knowledge of the main methodologies related to structural analysis (two-dimensional ones) and to the design of civil engineering structures;
- the ability to clearly explain the concepts learned and to use the terminology proper to the discipline in an appropriate way;
- the ability to understand the literature related to the topics covered in the course;
- the ability to acquire the methodological tools to continue the studies and autonomously provide for their updating and classification of the issues dealt within the field of Civil Engineering.
Evaluation criteria and assessment
The assessment of the global learning activity will be expressed through a final grade deriving 1/3 of the design activity carried out and illustrated during the oral examination, 2/3 for the other activities (questions, exercises) carried out during the oral examination.
