Prerequisites:

To successfully follow this teaching, it is necessary to have followed and passed the courses of Statics of Constructions and Science of Constructions, both propaedeutic to the course of Construction Technique.

Objectives

The Architecture student, in following the Construction Technique course, must complete a training course started with Statics and continued with Construction Science, aimed at achieving mastery of the concept of "structural behavior of a building". This allows him to know how to control the Organization and the Predimensioning of the structure, in such a way as to be able to reach both the "Definition of the safety conditions for the operating load in ordinary conditions" and the "Definition of the safety conditions for external loads (linked to the action of atmospheric agents, such as snow and wind, and seismic)”, as defined in the relevant Dublin descriptors.

Going into detail, to achieve the basic objective just described, it is necessary to acquire a series of "knowledge" of statistics, mechanics, the characteristics of structural materials, the definition of the loads acting on a structure, the methods of analysis of the different structural types (also in relation to the different types of structural materials, such as reinforced concrete, steel and wood), on the Codes in force and on Structural Safety.
Based on this knowledge, it is therefore possible to develop the "ability" to know how to set up a correct organization of the structure of a building and to know how to verify the safety conditions. In this regard, it is therefore essential to develop projects for simple building structures in the application part of the course.
This application part is also fundamental to refine the awareness (in the sense of "knowledge") that an architecture project is a multidisciplinary project where the different components: formal, functional, technical and technological, must contribute to a unitary and organic project.
This awareness therefore leads to the development of an "Overview of the Project"; "Ability" that allows you to develop the decision-making ability underlying the "autonomy of judgment" necessary in a professional activity.
The development of exercise projects also allows the student to develop graphic "communication skills", essential for making his project understood by both the professionals who will have to carry it out and the potential clients.
The alternation of traditional training moments (frontal lessons) with moments dedicated to the application part of the course (aimed at stimulating the ability to self-organize) helps to promote a methodological approach to study which (by improving the "ability to learn") will put the future professionals able to practice the subsequent self-learning processes, necessary for the critical updating of their knowledge.

The handouts and teaching materials (including those necessary for the development of the design exercises) will be available either on the e-learning platform and / or on web pages specially prepared for the course.

Teaching Methods

The teaching activity includes a theoretical part, with lectures, and an applicative part, with the assignment of simple design themes that will be developed by the student under the supervision of the teacher, according to weekly review cycles. These project themes can be developed by students individually or in small groups of up to a maximum of three components.

Evaluation methods

Verification of learning:

The exam consists in the discussion of the individual papers relating to the assigned exercises and in a test with theory questions, to be answered orally or in writing, on the topics developed during the course.
The results of any intermediate checks will also be taken into consideration in the evaluation.
The grade is out of thirty and will be obtained with an average of the grade obtained on the basis of the year's papers and the grade obtained on the basis of the theory questions.

Contacts/More Information

Reception hours will be defined, with a weekly cycle, specifically aimed at revising the project themes.
