works are performed on the dynamic response of structural models subjected to
ground vibrations and the results are verified with predictions from computer
programs using nonlinear dynamic analysis. The experimental facilities developed
in the Structural Mechanics and Strength of Materials Lab at UAP are used for
3-DOF dynamic system is created by a model 3-storied structure made of springs
(as columns) and timber plates (as slabs). The mass, damping and nonlinear
stiffness properties of the structure are measured from static loading
arrangement and free decay test. Arrangements for ground shaking are made from
simple combinations of pulley.
of the displacements are recorded with time. Several experimental situations are
simulated when the structural model is subjected to harmonic ground vibration of
constant amplitudes but different frequencies (30, 70, 110 rpm). For parametric
studies, different lab arrangements are also created by changing the mass and
observing the resulting modifications to the structural behavior. Moreover, the
numerical analyses are carried out in the time domain using linear as well as
nonlinear dynamic models.
