Learning objectives

Knowledge and understanding:
Knowledge of the mechanical behavior of concrete structures and theoretical models to describe them.

Knowledge of code rules (Euroceods2) for the design of reinforced concrete structures. Knowledge of the detailing and arrangement of reinforcement in the main structural elements.

Ability to choose, arrange and pre-design the different structural elements that constitute a simple reinforced concrete building. Ability to write the report and to draw the reinforcements.

Making judgments:
The student must be able to choose and set the proper dimensions of structural elements

Communication skills:
During the course the student should improve his technical dictionary.

Learning skills:
The student must acquire the ability to select the most appropriate design choices also considering options that are not perfectly identical to those given during the course. He will also be able to consult the main reference books of the field


Basis concepts on stress analysis and strength of materials are useful

Course unit content

Theoretical aspects and practice for the design of reinforced concrete structures and prestressed concrete structures (axial load, bending, shear, torsion, serviceability limit states, prestressed concrete structures, strut&tie for the analysis of corbels, foundations and walls). Design of a RC building (beam, column, slabs, stairs, balconies)

Full programme

1) Mechanical properties of concrete: compressive and tensile strenght, modulus of elasticity, combined stress behavior. [4]
2) Steel reinforcement: monotonic stress-strain law, yield stress, bond characteristics. [4]
3) Characteristic and design actions, partial safety factors, load combinations [4]
4) ULS for flexure and axial load. Strain diagram at ultimate limite state. Ultimate tensile and compression axial load. Members subjected to flexure. M-N interaction diagrams. Biaxial bending and axial force. [4]
5) ULS for shear. Member not requiring shear reinforcement, standard method, variable strut inclination method. Dimensioning of web reinforcement and detals. [4]
6) ULS for torsion. Behaviour of solid and thin-walled cross-section, variable angle truss mode, combined shear and torsion. [4]
7)Serviceability limit states. Control of stress. Cracking axial load and bending moment. Stabilized cracking and crack spacing. Tension stiffening. Control of cracking and evaluation of crack width. Bending moment-curvature diagram, checking deflection. [1]
8)Detailing of reinforcement. Spacing bars, anchorage of reinforcement, laps and mechanical couplers. Bundled bars. [4]
Detailing of members. Miniumum reinforcement, details of anchorage, regions with discontinuity in geometry and action. [4]
9)Columns, beams, slabs, walls, deep beams, footings. [4]
10) Prestress: prestressing cables pre-tensioned and post-tensioned, external prestressing, equivalent actions. Resolution of statically indeterminate beams prestressed cable, concurring. [2]
Loss of prestressing: release of the strands, friction, return of anchors, shrinkage, creep, relaxation of prestressing steel.
11) Creep and shrinkage: behavior of concrete over time, superposition in time, AAEM method, stress distribution in columns, prestressed beams and composite beams, time behavior of continuous beams, isomorphism theorems. [2]
12) Structural Analysis: strut and tie models for the design of corbels, walls, nodes, beam-column joints. [4]

Teaching methods

Frontal lectures, Excercises, Design project.

During the course the students (in groups of max 4 studens) will design a 2 floors building whose architectural drawings are provided (by dwg files) on the web page of the course. In particular, the students define the structural scheme and design floor slab, beam, column, foundation and stairs. The students prepare a report and the drawings of the RC structures. Students are assisted by tutors (for the period of one academic year)

Assessment methods and criteria

Written and oral examination with discussion of the design project. Registration at both written and oral examination is requested

--Written (2/3)
Two exercises in 3 hours with also theoretical questions. The use of notes, manuals and books is not admitted. Text f the exercises of the past 10 years is available on the web page of the course. The exercises usually require the solution of a simple statically determinate beam and the design/check of the critical parts. For each exercise a score of 15/30 points is given considering:
Knowledge of the topics of the course (50%);
Ability to solve an exercise similar to the one explained during the class (50%)
Students are admitted to the oral examination if they written part reaches a minimum score of 18/30.

--Oral - discussion of the project (1/3). Thestudent discusses the written exam and illustrates the design project. The following aspects are considering to form the score:
Knowledge of the topics of the course (60%); Communication skills (10%); Judgement ability (30%)
