LSDOF_LinearWilson
Purpose
transient response of linear SDOF system by exact integration of piecewise linear excitation
Synopsis
[u,udot,uddot] = LSDOF_LinearWilson (Deltat,omega,p,zeta,u0,udot0)
Description
LSDOF_LINEARWILSON transient response of linear SDOF system by exact integration of piecewise linear excitation [U,UDOT,UDDOT] = LSDOF_LINEARWILSON (DELTAT,OMEGA,P,ZETA,U0,UDOT0) function determines the transient response history of linear SDOF system(s) with eigenfrequency(ies) in row vector OMEGA, to acceleration history (force/mass) in vector P, for damping ratio(s) in row vector ZETA (default=0), and initial conditions in row vectors U0 (displacement) and UDOT0 (velocity) (default values=0); the time step of integration is DELTAT; the function integrates exactly the equations of motion for piecewise linear interpolation of excitation; the function returns the displacement history(ies) in array U, the velocity history(ies) in array UDOT and the acceleration history(ies) in array UDDOT arranged columnwise (column no=frequency no); Reference: A.K.Chopra, Dynamics of Structures, 2nd edition, pp. 167-171
