Acquiring basic knowledge related to the mechanical behavior of construction materials (steel and concrete) and the main structural elements and systems made with them. Gaining basic operational tools for structural sizing and safety check, aimed to the design of simple constructions. Topics such as classification and modeling of actions, characteristics of structural materials, criteria for design and verification of structural elements and an overview of complex structural systems will be covered.

The assessment process is divided into three phases: 1. STRUCTURAL PROJECT (in groups of two students – mandatory submission to access the written exam): Each group is required to develop a design report consisting of three parts, focusing on a simple multi-storey building: • Part 1 – General framework: identification of a structural system consistent with the architectural and functional context, including a qualitative analysis of loads and load transfer strategies; • Part 2 – Design of a steel structural element: modeling, structural design and safety verification; • Part 3 – Design of a reinforced concrete structural element: modeling, structural design and safety verification. The project will be reviewed during the course and must be submitted at the time of the written test. It will be discussed individually during the oral exam. 2. WRITTEN TEST (individual, duration: 60 minutes – required to access the oral exam): An individual test aimed at solving a basic structural design or verification problem, intended to assess the student’s ability to independently tackle elementary structural engineering tasks. 3. ORAL EXAM (individual, duration: 45–60 minutes): An individual interview aimed at: • verifying the understanding of theoretical topics covered in the course; • critically discussing the group project; • assessing the ability to link theoretical concepts with practical applications. Grade assignment: The final grade will be based on: • the completeness, technical accuracy, and clarity of the design report; • the result of the written test; • the quality of the oral performance in terms of theoretical mastery, critical thinking and technical vocabulary.
