The course on TECNICA DELLE COSTRUZIONI aims to present the fundamental principles of structural safety of reinforced concrete (RC) structures, focusing on different methodological approaches for their calculation. The main physical and mechanical properties of structural concrete and reinforcing steel will be introduced. Elastic calculation approaches for the serviceability limit state of RC structures will be presented, with a significant portion dedicated to the study of ultimate limit state conditions. Additionally, degradation phenomena and durability will be discussed, covering their main causes and considerations in the design phase. Students will undertake design projects involving simple cases such as a reinforced concrete slab, a series of continuous beams, and a base pillar.
The educational objectives of the course Tecnica delle Costruzioni include learning theories, techniques and calculation methodologies for the design of reinforced concrete construction. Students will develop technical and scientific skills in structural design, focusing on structural safety and durability of RC structures.
The course of Tecnica delle Costruzioni aims to achieve a series of detailed educational objectives that will provide students with the theoretical and practical skills necessary for the structural design of reinforced concrete (RC) buildings.
Students will be able to demonstrate the following skills and knowledge:
To successfully follow the course of Tecnica delle Costruzioni, students must have a solid foundation of knowledge and skills in several key areas, acquired in previous modules, including a strong background in mathematics, statics, and structural mechanics.
Frontal Lectures: conducted to provide a theoretical foundation on the main topics. Lectures include theoretical explanations, practical examples, and in-depth case studies.
Use of PCs and Software: Students become acquainted with specific software used in the construction sector, such as structural modeling programs (e.g., finite element analysis software) and structural calculation software. Practical lessons may focus on using these tools for structural design and analysis. Throughout the course, Excel spreadsheets, FTOOL, and VCASLU are used.
Design RC project: A crucial component of the course involves the completion of an individual RC design project. Students have the opportunity to apply all acquired skills to solve a real or simulated structural design problem under the supervision of the instructor.
Students who have a valid certification of physical or learning disabilities on file with the University and who wish to discuss possible accommodations or other circumstances regarding lectures, coursework and exams, should speak both with the teacher and with the Department of Architecture and Design's disability referent (https://architettura.unige.it/commissioni_e_referenti_dipartimento).
