Response of SDOF systems to periodic excitation • Periodic function: repeats itself every period T • P(t+T)=p(t) for any t T
Finding steady state response of a SDOF system to a periodic excitation • Decompose excitation into series of harmonic functions • Find response to each harmonic function • Superimpose responses
Finding steady state response of a SDOF system to a periodic excitation (continued)
Finding steady state response of a SDOF system to a periodic excitation (continued) • Find steady state response to each component of the series • Superimpose response to find total response
