Abstract
Taking geometric non-linearity into account anoscillator of the
form as aportal frame with a rigid traverse and with ideal-elastic
ideal-plasticclamped-in columns behaves under horizontalexcitation
as an ideal-elastic hardening / softening-plastic oscilator given
that the columns carry atension/compression axial force. Assuming
that the horizontal excitationof the traverse is Gaussian white
noise, statistics related to the plastic displacement response are
determinedby use of simulation based on the Slepian modelprocess
method combined with envelope excursion properties. Besidesgiving
physical insight the method givesgood approximations to results
obtained by slow direct simulation of thetotal response. Moreover,
the influence of a randomly varying axial column force
isinvestigated by direct response simulation. This case
corresponds to parametric excitation as generated by the vertical
acceleration component in a quake.
