Learning objectives
To present basic concepts and tools for structural design, with reference to statically determinate and indeterminate elastic frames (beam systems).
Prerequisites
Analisi A-B, Analisi C, Geometria, Meccanica Razionale, Scienza delle Costruzioni A (Structural Mechanics A).
Course unit content
The problem of De Saint-Venant. Fundamental hypotheses, indefinite equations of equilibrium, elasticity equations and boundary conditions. Centred axial force, flexure (bending moment), biaxial flexure, eccentric axial force, torsion, bending and shearing force.
Computation of displacements for framed structures. Differential equation of the elastic line; theorem of virtual work for deformable beams; thermal distortions and constraint settlements.
Statically indeterminate framed structures. Theorem of virtual work: structures subjected to loads, thermal distortions and constraint settlements.
Instability of elastic equilibrium. Euler’s critical load and free length of deflection; omega method.
Complex statically indeterminate framed structures. Force method and displacement method: general concepts.
