34172 - Structure Design (A)

Learning outcomes

The course aims at providing the students with the expertise for conceive and design a structural system able to safely bearing dead , wind, live and seismic loads.

The knowledge and expertise to be learned by students regards mainly: the structural concept of buildings, the fundamental technical codes, the steel structures design, the r.c. structures design, the basic theory of seismic design and of innovative methodology design.

 

Course contents

1) Basic theory:

1.1) The role of structural design in the architectural design

1.2) Mechanical properties and characteristics of materials used commonly in constructions (reinforced concrete, steel, wood, alluminium)

1.3) Technical codes (italian codes, eurocodes)

2) The structural conception:

2.1) The designing tools: science of construction

2.2) The systems resistant to vertical actions (beam and columns systems)

2.3) The systems resistant to horizontal actions (vertical and horizontal bracing; pendulum structures and moment resisting frames)

As concerns the teaching methods of this course unit, all students must attend Module 1, 2 [https://www.unibo.it/en/services-and-opportunities/health-and-assistance/health-and-safety/online-course-on-health-and-safety-in-study-and-internship-areas] on Health and Safety online

Assessment methods

The assesment will encompass a final exam.

According to the rules of the "corso di studi", in order to access the final exam the student will have to be present to a sufficient numer of classes and have mastered the basic concept of the course "con profitto".

In order to assess the mastering of the basic concepts, the students will have to present their design work in two seminars.

The first seminar is held in the last week of class of April and in this case the students will illustrate their design of a steel structure (5 to 8 marks in case of positive judgement).

The second seminar is held in the last week of class of May and in this case the studdents will illustrate their design of a concrete structure (5 to 8 marks in case of positive judgement).

Once granted the access to the exam, the student will have to sustain an oral exam aimed at assessing the capabilities of the studdent in dimensioning and designing a steel and concrete structure.

The pass of the exam is guaranteed to the students that will show a sufficient capabilty of mastering the information given in class and in particular in using formulas, concepts and quantities necessary to complete a structural design of a building structure (8 to 14 marks depending on the exam preparation of each student).

A higher grade will be given to the studdents that will show to use with confidence the concepts given in class solving complex problems and showing a good operative capability.

Fail can be related to unsufficient knowledge of key concepts, lack of technical language and / or insufficient operative capabilities.
