BENCHMARK PROBLEM FOR CONTROL OF BASE ISOLATED BUILDINGS

Abstract eng:
This paper presents the benchmark problem definition for 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 non-linear bearings and 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.
