The course is developed through lectures, work and structural-design reviews and specific seminars. Two software for structural modeling will be explained and used. The Mathematica software for the qualitative solution of the problems related to the theoretical part. This tool allows students to understand the proposed physical-mathematical models as well as focus on the conceptualization of a structural problem. The SAP2000 software will be used to conceptualize and implement a structural model of the architectural project, and to evaluate the numerical response, once the design loads have been defined. This allows students to have a tool for the design of structural elements.Attendance
students who do not have at least 75% attendance will not be admitted to the final exam. The attendance is verified in class by the teacherType of evaluation
Three/Four individual homework are assigned during the course, to be delivered in written form and for which each student will be evaluated. The oral exam will focus on the theoretical topics, developed in class, and on the discussion of the project. The final project concerns the structural modeling and study of a selected part of an architectural project, in agreement with the teacher. It is delivered with drawings and a small report on the numerical model and structural analysis. Instructions for exams in remote mode: - the final project will be delivered in PDF format within the day before the exam. - The exam is carried out as an individual remote meeting with Microsoft Teams or other video conferencing platform. - It is necessary for the student to be able to share the screen, in order to show (if required) the ability to use the SAP2000 software and the Mathematica software. He / she must also be able to show (live streaming - with any useful platform, or by writing on a graphic tablet) a blank sheet on which he / she writes and explains the formulations required for the theoretical part, draws the structural schemes useful for the discussion and possibly draw analytical diagrams (deformed configurations and stress diagrams). teacher profile teaching materials

The course consists of lessons, exercises and design applications. The lessons are ex-cathedra, the exercises and the design applications are guided by the teacher and the assistant teacher. The course also consists of a part of recovery of the contents of structural mechanics of the three-year degree. This content is retrieved through distance learning, with the help of two YouTube Channels, named as "Portale di Meccanica" and "Corso di recupero di Meccanica Strutturale".Attendance
Attendance of the course is mandatory, because most of the work is done in the classroom, especially in relation to the design exercises. Mandatory attendance means attendance of at least 75% lessons.Type of evaluation
1. How to carry out the exams in the traditional way (in presence): The exam consists of three tests: a) a discussion on structural design choices, carried out through the examination of graphic designs and a short technical report; b) a practical test of the detailed knowledge of SAP2000, of its modeling skills, but also of the reading and interpretation of the results produced by the software; c) an oral test, on the theoretical contents of the course, with exercises performed on the impression and theoretical demonstrations carried out with symbolic language. 2. How to carry out the exams remotely in the event of a health emergency (on the Teams platform): a) for discussion on the project, direct via Teams with screen sharing, if the connection allows it. Where it is not possible, the project is sent two days before to the teacher, or is uploaded to the web 2.0 mechanical portal (http://design.rootiers.it/strutture/), and its evaluation weighs 1/3 of the evaluation. overall exam; b) the practical test of knowledge of SAP2000 is carried out with screen sharing via Teams and the evaluation of this test weighs for one third of the exam; c) the oral test is an individual test and is carried out with the joint use of teams and whatsapp in camera mode, and its evaluation weighs a third in the overall assessment of the exam.
