ABSTRACT
The benchmark
problem is for passive, active and semiactive control of seismically excited
base-isolated buildings. The objective of this benchmark study is to provide a
well defined base isolated building with a broad set of carefully chosen
parameter sets, performance measures and guidelines to the participants, so
that they can evaluate their control algorithms. The control algorithms may be
passive, active or semi-active. The benchmark structure considered is an eight
story base isolated building similar to existing buildings in Los Angeles, California.
The base isolation system includes both linear and nonlinear bearings and
control devices. The superstructure is considered to be a linear elastic system
with lateral-torsional behavior. A new nonlinear dynamic analysis program has
been developed and made available to facilitate direct comparison of results of
different control algorithms.
