LEARNING OUTCOMES AND COMPETENCES TO BE ACQUIRED:

THE COURSE OF “THEORY AND DESIGN OF BUILDINGS IN SEISMIC AREAS” (12 CREDITS) IS BASED ON A THEORETICAL PART (I MODULE) AND A PART DEVOTED TO PRACTICAL DESIGN (II MODULE) OF REINFORCED CONCRETE AND STEEL BUILDINGS IN SEISMIC AREAS. THE THEORETICAL PART IS AIMED TO LEARNING THE FUNDAMENTAL PRINCIPLES FOR DYNAMIC ANALYSIS AND DESIGN OF BUILDINGS IN SEISMIC AREAS. THE PART DEVOTED TO DESIGN IS AIMED AT THE DEVELOPMENT OF DESIGN EXAMPLES DURING WHICH, ALSO THROUGH THE USE OF NUMERICAL EXAMPLES, THE COURSE PROVIDES THE INFORMATION NEEDED FOR THE PREPARATION OF A PROJECT WORK THAT STUDENTS WILL HAVE TO DEVELOP INDEPENDENTLY, SUPPORTED BY THE ACTIVITY OF TUTORING THAT IS AN INTEGRAL PART OF THE COURSE. THE ESSAY CONSISTS IN THE DESIGN OF A REINFORCED CONCRETE BUILDING LOCATED IN A SEISMIC ZONE. THE DESIGN CHARACTER IS A FUNDAMENTAL ASPECT OF THE COURSE (I AND II MODULE). THE STRUCTURAL DESIGN DOCUMENTS ARE DEVELOPED STARTING FROM AN ARCHITECTURAL DESIGN, THEREFORE THE WORK TO BE DEVELOPED IS A REAL PROJECT EXPERIENCE, RATHER THAN A SIMPLE VERIFICATION OF A GIVEN STRUCTURE. THEREFORE, THE COURSE IS FOR STUDENTS, IN BUILDING ENGINEERING SECTOR, THE FIRST TASK IN A COMPLETE STRUCTURAL DESIGN IN SEISMIC AREAS STARTING AND INTERACTING WITH THE ARCHITECTURAL DESIGN.
THE SKILLS RESULTING FROM PLANNED ACTIVITIES CONCERN THE ABILITY IN THE MODELLING OF SPATIAL STRUCTURES AND THE ABILITY TO ANALYZE THE DYNAMIC RESPONSE UNDER SEISMIC ACTIONS AND TO VERIFY THE SAFETY LEVEL OF STRUCTURES DESIGNED IN COMPLIANCE WITH THE REGULATIONS.

EDUCATIONAL TARGETS:

KNOWLEDGE OF THE MAIN RULES FOR THE DESIGN OF REINFORCED CONCRETE BUILDING STRUCTURES IN SEISMIC AREAS. KNOWLEDGE OF METHODS FOR THE EQUIVALENT STATIC ANALYSIS AND DYNAMIC ANALYSIS OF STRUCTURES IN SEISMIC AREAS. ABILITY TO UNDERSTAND THE PHILOSOPHY OF SEISMIC-RESISTANT DESIGN OF STRUCTURES AND SITUATE IT IN THE CONTEXT OF NATIONAL AND INTERNATIONAL SEISMIC CODES.

APPLYING KNOWLEDGE AND UNDERSTANDING:

KNOWLEDGE REGARDING HOW TO DESIGN AND ANALYZE STRUCTURAL SYSTEMS, EVEN COMPLEX FOR MULTI-STOREY BUILDINGS IN SEISMIC AREAS.

MAKING JUDGMENTS:

KNOWLEDGE REGARDING HOW TO IDENTIFY THE MOST APPROPRIATE METHODS FOR THE ANALYSIS OF A STRUCTURAL SYSTEM.

COMMUNICATION SKILLS:

ABILITY TO WORK IN A TEAM AND ABILITY TO DISCUSS AND COMMUNICATE CONCERNING THE ANALYSIS AND STRUCTURAL DESIGN IN SEISMIC AREAS. ABILITY TO COMMUNICATE THROUGH THE MOST MODERN GRAPHICAL TOOLS THE DESIGN SOLUTIONS IDENTIFIED.

LEARNING SKILLS:

ABILITY TO APPLY THE KNOWLEDGE ACQUIRED IN CONTEXTS DIFFERENT FROM THOSE PRESENTED DURING THE COURSE AND TO DEEPEN THE TOPICS COVERED BY THE STUDY, IN COMPLETE AUTONOMY, INCLUDING THE ADOPTION OF STRUCTURAL MATERIALS OTHER THAN THOSE ADOPTED IN THE DEVELOPED DESIGN ESSAY.
Prerequisites
FOR THE SUCCESSFUL ACHIEVEMENT OF COURSE OBJECTIVES, ADEQUATE BASIC MATHEMATICAL KNOWLEDGE AND KNOWLEDGE OF THE BASIC PRINCIPLES AND METHODS OF THEORY OF STRUCT,URES AND STRUCTURAL ENGINEERING ARE REQUIRED. IN IN PARTICULAR, THE COURSE OF STRUCTURAL MECHANIC IS REQUIRED AS PREPARATORY.
