Material covered in Structural Analysis and Seismic Engineering is considered as assumed knowledge

Learning outcomes
KNOWLEDGE AND UNDERSTANDING:
The course aims at providing the fundamentals on some of the most innovative and advanced research topics in the field of civil engineering. By improving skills deriving from the first cycle degree, the student improves his knowledge in the following fields: modelling of beams and bridge decks, structural monitoring, innovative seismic protection systems of both new and existing buildings.
CAPACITY TO APPLY KNOWLEDGE AND UNDERSTANDING:
The student gains advanced practical skills in specific civil engineering areas by means of practical exercises and individual work, constituted by an in-depth study of one of the topics presented in the course.
TRANSVERSAL SKILLS:
Individual practical exercises improve the student's ability to conduct experiments; the in-depth study of one of the topics presented in the course develops the self-learning and communicative skills.

Program
Modelling of steel-concrete composite beams with deformable shear connection; displacement based approach, shear-lag effect, cross section warping and shear deformability; closed form solutions and numerical solutions with step-by-step procedure, finite element method and finite difference method. Steel structures in seismic areas: hyerarchy rules and design requirements for the main dissipative structural typologies (moment resisting frames and frames equipped with concentric or eccentric dissipative braces). Innovative strategies for seismic protection of structures: base isolation (High Damping Rubber Bearing - HDRB, with lead core - LRB; friction pendulum devices) and dissipative braces (with hysteretic behaviour, Buckling Restrained Braces - BRBs); design methods and safety verifications proposed by codes. Techniques for the seismic upgrading and retrofit of existing structures. Sesimic design of isolated bridges. Evaluation of the seismic response of structures accounting for soil-structure interaction: analysis methodologies. The substructure method: kinematic interaction analysis of the soil-foundation system and inertial interaction of the superstructure on compliant base. Structural dynamic identification: excitation techniques and analysis in the time and frequncy domains.

Development of the examination
LEARNING EVALUATION METHODS
The evalulation of student learning is based on an oral exam consisting in a discussion of a short dissertation, developped by the student on one of the topics covered during the course; and in some theoretical questions on the topics covered during the course. To access the oral exam the student is required to have completed the short dissertation.

LEARNING EVALUATION CRITERIA
Through the short dissertation and the oral exam 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 is expressed in thirtieths

FINAL MARK ALLOCATION CRITERIA
The student is expected to pass both assessments. The final mark of the course will be calculated after the oral exam as the average of the marks received for these two assessments. The 'lode' will be awarded to students who, having correctly completed the two assessments, show an outstanding understanding in the subject.
