Course Objectives
The student is required to prove to master the fundamental principles of structural analysis and to have reached a sufficient level of knowledge on specific issues. The student must further demonstrate the ability of correctly using all design tools through the design and assessment of simple R.C. beams.
Course Prerequisites
Prerequisites for the course are the basic knowledge of statics and of the basis of structural mechanics as well as the knowledge of construction material technology.
Prerequisite courses:
Construction Science
Construction Technology
Teaching Methods
The course takes advantage and is part of the innovative teaching project “On Solid Foundations”, aimed at fostering solid training and gap-less through flexible and modular training courses, that the student can select based on their personal background and cognitive skills, and the level of preparation, enabling the most motivated student the access to excellence learning paths.
The course will be structured with frontal lectures and exercises, with particular attention to fostering proactivity and direct participation of the students.
The students will benefit with additional materials, for further training at home. To verify learning, the students can use a series of self-assessment tests that will allow them to identify and fill any gaps to promote progressive learning “On Solid Foundations”.
Assessment Methods
The exam has two options: 1) three-hour written test, in which the student will be asked to design and verify a simple structural element. The test is graded in thirtieths. After passing the written test, the student must take an oral test, aimed at verifying understanding of the topics studied. 2) the development of a project of design of a reinforced concrete building subjected static loads, which will be discussed during an oral test. The evaluation of the two tests, written/project and oral, is in thirtieths. The final grade recorded for the integrated course is the algebraic average of the partial grades obtained in the two modules.
