Seat Ingegneria
A.A. 2015/2016
Credits 9
Hours 72
Period II
Language ENG

Prerequisites
Material covered in Statics and Structural Mechanics is considered as assumed knowledge.

Learning outcomes
The course aims to provide the student with the theoretical knowledge and practical skills required to design and assess steel structures. The course consists in theoretical lectures and practical exercises.

Program
Design principles: idealization of the structural system: geometry, discretisation, support and loading conditions; methods of limit state design and allowable stress design. Loads on structure: dead and live loads, wind and snow loads, thermal loadings; load combinations for the strength (ULS) and serviceability limit states (SLS). The structural design of steel buildings: single storey and multi storey steel framed buildings. Structural steel: designation, material properties, cross-sectional shapes of hot-rolled and cold-formed sections, standard tests for the characterisation of the material mechanical properties. Design of structural steel members: design stress and allowable stress; design of members subjected to axial compression or tension, moment, shear and torsion force, and combined actions, according to EC3 and Italian Technical Code methods; design at service conditions. Bolt and weld groups: bolt group behaviour and design, weld group behaviour and design. Bolted and welded connections: design of spliced connections and plate cleats. Structural stability: buckling of columns subjected to axial loads, uniaxial bending and combined actions; introduction to flexural-lateral buckling.

Development of the examination
LEARNING EVALUATION METHODS
The assessment of student learning is based on three tests: - the development of practical exercises concerning the design of a steel structure, through guided tutorials; - a written test concerning the design of a steel structure; - an oral assessment, consisting in the discussion of both the developed exercises and the written test, and in some theoretical questions on the topics covered during the course. The latter may also be a written examination (if required by the presence of formulas or demonstrations) followed by an oral discussion. To access the oral examination, the student must have completed the proposed exercises and obtained a sufficient evaluation in the written test. The written and oral examinations must be sustained in the same examination session.

LEARNING EVALUATION CRITERIA
Through the presented exercises, the written and the oral assessments, the student must demonstrate to have learned the topics covered during the course and to be able to present them correctly, by adopting a proper technical terminology.

LEARNING MEASUREMENT CRITERIA
The evaluation of each test is expressed in thirtieths.

FINAL MARK ALLOCATION CRITERIA
After the oral examination, a final mark is defined for the presented exercises and for the written and oral assessments. The student is expected to pass all tests. The final mark of the course will be calculated as the average of the marks received in each test. The 'lode' will be awarded to students who, having correctly completed the three assessments, show an outstanding understanding in the subject.
