Training objectives
- The lectures are aimed at giving the student a comprehensive vision of the design of structures together with the technical tools for the choice of the structural solution. The lectures deal with different aspects of structural design, from load and material characterisation to the choice of the structural scheme, from the design of structural elements to the connection details, from the stress analysis to the evaluation of the safety levels.
Knowledge
Students will gain knowledge about the basic design tools:
- load characterisation for buildings
- structural material characterisation
- methods for the evaluation of safety levels
- analysis of structural connections and relevant execution details
Skill
Students will gain skill in taking the basic design choices:
- choice of the structural shape
- design of structural elements
- design of structural connections Prerequisites
- Mechanics of Solids and Structures is a propaedeutic course. Knowledge is required about continuum mechanichs as well as isostatic and hyperstatic structures.
Course programme
- Loads on structures (16 hours):
dead load, live load, snow and wind loading, earthquake loading, lateral earth pressure, indirect loads.
Safety levels evaluation (8 hours):
limit state design: limit states for serviceability and ultimate limit states.
Frame structures (8 hours):
general properties; stress analysis; detailing of beams and compression members; notes on dynamics of structures.
Two-dimensional structures (8 hours):
flexural behaviour of plates; design of floor slabs and retaining walls.
Reinforced concrete structures (20 hours):
mechanical properties, shrinkage, creep; tests for material characterisation; steel-concrete bonding; design of members with axial load, flexure, shear and torsion; notes on pre-stressed reinforced concrete.
Steel structures (10 hours):
mechanical properties of material; members, joints and overall structural behaviour; strength and stability of compression members and thin-walled beams; fatigue phenomena; bolted and welded joints.
Soil Mechanics and Foundations (20 ore):
notes on soil mechanics; in situ and laboratory tests; surface foundations; foundation piles; load bearing capacity evaluation. Didactic methods
- The course is organised in lectures on the programme topics. The student is requested to design a reinforced concrete building, or a steel building, providing execution details for the basic structural members (floor slabs, beams, columns, stairs, foundations). Exercises in hall will help the student in the design process.
Learning assessment procedures
- The examination consists of written and oral tests. Written test is preliminary (four hours duration). It is aimed at evaluating the basic design skill by requesting the student to design basic structural elements of a building. If the result is positive, then the subsequent oral test can be tackled. The oral test is aimed at evaluating acquired knowledge levels by requesting the student to discuss the structural choices implemented in the coursework building design as well as key aspects of structural design analysed during lectures.
