Sessions to be held at the
Second World Conference on Structural Control
June 28 - July 1, 1998 in Kyoto, Japan

Benchmark Comparisons in Structural Control

Abstract: The next generation of benchmark structural control studies were initiated by the Working Group on Building Control (chaired by Profs. J.N. Yang, K. Seto and C.S. Yeh) during the Second International Workshop on Structural Control held December 18-20, 1996, in Hong Kong. As stated by the Working Group, the goal of this effort is to develop benchmark models to provide systematic and standardized means by which competing control strategies, including devices, algorithms, sensors, etc., can be evaluated. This goal drives the next generation of structural control benchmark problems, and its achievement will take the structural control community another step toward the realization and implementation of innovative control strategies for dynamic hazard mitigation. These sessions bring together a group of highly qualified researchers to study two well defined benchmark problems. The first benchmark problem focuses on seismically excited buildings. The second proposes a benchmark problem for wind excited buildings.

All researchers are welcome to study the structural control benchmark problem presented for this session. If you are interested in receiving a copy of the paper providing the problem definition or the problem data/models, please click here.

Benchmark Sessions

The three sessions each have 6 papers. The first papers in sessions I and II provide an overview and definition of the benchmark problems. The remaining 16 papers will apply various control strategies to this problem and discuss the ability of the respective approaches to meet performance specifications while not violating control constraints. Click on the title of the papers listed below to see the abstract the respective contributions to the benchmark sessions. These papers will appear in the Proceedings of the 2nd World Conference on Structural Control.
