Educational Goals

Students learn the local and global behavior of reinforced concrete buildings under both vertical and horizontal loads.

Students study the main concrete material properties and the action typologies.

Students learn how to properly proportion, design and verify, both at serviceability and ultimate limit states, simple and complex structural elements made by reinforced concrete and prestressed reinforced concrete, even with the adoption of finite elements.

Students study some peculiar aspects of reinforced concrete, such as creep, shrinkage, strut&tie model and plastic limit analysis.

Students who will follow also “Advanced Reinforced Concrete” can design a reinforced concrete building, whether in group or individually, under both vertical and horizontal loads, producing detailed design drawings and a calculation report.

Content

The course is designed for civil and environmental engineering students and intends to deepen the knowledge on the reinforced concrete and prestressed concrete structural elements, with particular attention to the limit state design method. The aim of the course is to provide the students with the principles and roles of the design and verification of concrete structures.

Extended Syllabus

1. Course introduction: Historical overview on the reinforced concrete use and production.
2. Materials: Ordinary and high performance concrete; mechanical and rheological properties of concrete. Mono-axial and pluri-axial stress states of concrete. Mechanical properties of steel.

3. Structural safety: The semi-probabilistic limit state method. Actions and resistances design values. Limit state design structural verifications.

4. Ultimate limit state (ULS) in flexure: Experimental behaviour of a reinforced concrete beam. Design assumptions, possible ranges of strain distributions, ductile and brittle behaviour, cross-section ultimate moment resistance.

4. Combined flexure and axial force ULS: Design assumptions. Construction of the axial force-moment interaction envelop.

5. ULS in Shear: Experimental behaviour. Members requiring and not requiring design shear reinforcement. Variable angle truss model. Punching Shear.

6. Serviceability Limit States (SLS): Calculation of crack widths. Deformation of cracked and uncracked beams. Stress Limits. Tension stiffening. Bonding.

7. Prestressed Concrete: Historical overview. Pre-stressing levels. Pre and post-tensioning systems. Bonded and unbonded tendons. Short and long-term p/s losses. Comparison between the moment-curvature diagram of reinforced and prestressed concrete beams. Equivalent tendon. Verification at prestress, after pre-stress losses, at SLS and ULS.

Methods of Provision

Conventional

Teaching Methods

Chalk and talk style lectures and tutorials will be generally provided. Occasionally slides and presentations will be utilized.
At least two seminars, one visit to the University Structural Laboratory and one visit to a construction site will be organized.

Assessment Methods

The examination consists of written test and of an oral test if the students has passed the written test.
For the students who will follow “Advanced Reinforced Concrete” the exam can consist of a discussion of a single assignment/group design project and an oral test.
