## Learning outcomes

At the end of the course the student will be able to manage advanced methods for the verification and design of concrete and steel structures. Considered methods are based on rigorous mechanical approach but also simplified models for one- and two-dimensional structures will be practived. A variety of civil engineering structures will be analysed. The advanced methods will be used to solve some real problems, with reference to European codes.

## Course contents

The course is mainly focused on methods for analysis and design of structures with particular attention on steel structures.

Part 1: Principles of structural analysis and design

1.1 GENERAL PRINCIPLES

- The design process and the role of the structural engineer

- The framework of the current technical codes (Italian codes and Eurocodes, USA specifications).

- Basis of structural design: safety-checking formats (admissible stresses and ultimate limit states)

- Materials

1.2 CONCEPTUAL DESIGN

- Vertical-resisting systems

- Horizontal-resisting systems (bracing systems, shear wall systems, pendular systems and moment-resisting frames).

1.3 SRUCTURAL ANALYSIS

-Fundamentals of hand-methods of structural analysis of simple structures: statically determined structures, statically undetermined structures: equilibrium and compatibility , Cross method,

-Numerical methods of structural analysis: linear and non-linear analysis

Parte 2: Design of steel structures

2.1 Principles

-Structural systems

-Reliability of steel structures.

-Material.

2.2 Serviceability limit states

- Vertical Deformations

- Horizontal deformations

-Other SLS

2.3 Strength of members

- Axial strength, Bending strength, shear-torsion, complex states

2.4 Stability of members

-Flexural buckling

-Lateral-torsional buckling

-Instability of frames: fundamentals

2.5 Connections

-welded connections

-bolted connections

2.6 Fatigue

- Palmgren-Miner rule

Part 3: General concepts for structural design of concrete strucutres

3.1 Design of RC frame structures

Verification and design rules for RC sections under axial-bending loads according to the ultimate limit state method. Verification and design rules against shear and torsion. Provisions by European Guide Lines (Eurocodes).

3.2 Ductility of RC structures

Moment-curvature diagrams, tri-linear and bi-linear approximations. Ductility of RC sections under bending. Plastic hinge and admissible plastic rotation for RC elements under bending, Eurocode criteria. Influence of axial force. Examples. Ductility at sectional and structural scales.

## Teaching methods

In regular classes, problems concerning the modelling and the design of structures are discussed. Structural solutions and details will be shown and discussed. Guidelines for different structural problems reported in national and international codes will be considered. Some classes will be devoted to show designs of actual realizations concerning the subjects of regular classes.

## Assessment methods

Final mark will be given according to a series of written tests (two homeworks, a midterm and a finalterm) and a elective oral examination. The oral examination is for the students that would like to improve the grade of the written part. During the oral will be verified the personal preparation of the student and his knowledge on the main theoretical aspects of the course.

They aim to establish the knowledge and skills achieved by the student as well as to evaluate his/her technical language with reference to the topics discussed. A positive exame requires demonstration of adequate reasoning capacities and problem solving in relation to the key-concepts discussed in the course. The student should know and understand all basic theoretical concepts illustrated in the lectures.
