Abstract:
This paper focuses on the benchmark control problems for
seismically excited nonlinear buildings defined by Ohtori et al, [I].
This benchmark study focuses on three typical steel structures, 3-,
9- and 20-storey buildings designed for the SAC project for Los
Angeles in California region. The first stage of applying the fuzzy
controller to this benchmark study for the 3-storey building is
reported. The main advantage of the fuzzy controller is its
inherent robustness and ability to handle the non-linear behaviour
of the structure. This benchmark study is based on a number of
evaluation criteria and control constraints and these limitations
are considered in the design of the fuzzy controller. The
performance of the controller is validated through the computer
simulation on MATLAB. The results of the simulation show a
good performance of the fuzzy controller to reduce the response of
the building under different earthquake excitations. In the next
stage, the study of the fuzzy controller will be extended to the 9-
and 20-storey buildings specified in this benchmark study.
