Learning outcomes:
The scientific knowledge needed for the optimum design of the building is a combination of structural elements with the complexity of the physical and the economical factors.
This course teaches the integration of different structural materials to achieve a functional product. Furthermore, the technological, organizational and economical factors are continuously present in the design process.
The course has the following goals:
1. Basic understanding of material properties, mainly masonry, concrete, reinforced concrete, prestressed concrete, wood and steel.
2. Ability to calculate the structural elements of a simple structure.
3. Ability to decide/select the appropriate structure: reinforced concrete vs masonry or wood vs steel.
4. Understanding of the main standards and regulations that govern the design process.
5. Ability of a correct usage of the main design codes for loading, structural materials, structures.
Basic principles. Buildings, structures, elements.
Loads, forces. Force moment. Force as a vector. Resultant force and moments. Analytical resultant of a system of forces.
Rigid body equilibrium without constraints. Moment of force with respect to a point. Constraints theory. Supports. Statically determinate and indeterminate structures.
Straight bars under tension, compression, bending, shear, torsion.
Loads-stresses differential relations. Axial, shear force and bending moments diagrams for beams and columns.
Shell elements.
Structural materials: wood, steel, concrete, reinforced concrete, prestressed concrete, masonry.
Foundation structures and supporting soil. Difficult terrain environments. Building behavior on difficult terrain environments.
Buildings loads
Evaluation of gravity loads for a five storey reinforced concrete structure.
Causes and effects of earthquakes. Seismic design and seismic performance. Structural properties: stiffness, strength, ductility. Essentials of structural systems for seismic resistance: - structural systems for seismic forces, gross seismic response, influence of building configuration on seismic response, structural classification in terms of design ductility level.
Evaluation of horizontal loads for a five storey reinforced concrete structure. Preliminary design of structural elements: slabs, beams, columns and foundations.
