STOCHASTIC DIFFERENTIAL EQUATIONS FOR STRUCTURAL
ENGINEERING
Held by Prof. Claudio Floris
COURSE DESCRIPTION
- Theory of the stochastic processes with emphasis to the process calculus.
Itô's and Stratonovich's integrals, Wong-Zakai's corrective terms. Classic
stochastic differential equations (SDE): Brownian motion, scalar SDE's
(generalized Langevin equations), multidimensional SDE's. Fokker-PlanckKolmogorov's differential equation and Kolmogorov backward differential
equation, solutions in the transient regime and at the equilibrium.
- Examples relevant for the Structural Engineering: the stochastic second
order oscillator with external or parametric excitation, the seismic and wind
excitation; the continuous beam modelled as a s.d.o.f. system; the Duffing
oscillator as model of a beam or a plate with second order effects.
- Approximate methods for the statistical characterization of the solution X(t)
or X(t) of an SDE: equivalent linearization, moment equation approach,
stochastic averaging.
