The Berkeley Earthquake Protective Systems Group and the PROSYS Online Database

Introduction

This site has been developed to disseminate data on design, testing, and implementation of passive earthquake protective systems. Because of the tremendous advances which have taken place in this field over the past two decades, there is substantial demand for detailed experimental results on individual components and structural systems incorporating innovative protective systems. However, these experimental research results are scattered throughout the technical literature. Also, as the number of applications has increased worldwide, it has become difficult for practicing engineers to stay abreast of the evolutions in design criteria in the many countries utilizing these technologies.

The mission of this site is to:

• Catalog experimental results on individual passive protective systems components as well as on structures incorporating such components
• Provide comprehensive lists of completed applications (buildings, bridges, and other civil engineering structures) throughout the world
• Compile current information on design approaches and philosophies, primarily by referencing codes and standards for structures incorporating earthquake protective systems
• List current research activities and personnel involved in protective systems at Berkeley

As a first step, a WWW-queryable database has been implemented which catalogs test results on individual protective systems components (PROSYS). This will be extended to include interlinkages with system tests and applications in the near future.

Available Information

• Background and Classification - a brief introduction to the various types of protective systems devices and technologies
• Catalogs of Applications - lists of buildings, bridges, and other structures incorporating protective systems
• Component Database (PROSYS) - a queryable database of tests on individual devices or groups of devices
• System Database - a queryable database of tests on systems (complete structures or structural models) incorporating earthquake protective systems (earthquake simulator tests, vibration tests of completed structures, etc.)
• Codes, Regulations, and Guidelines (under development) - a summary of documents applicable to the design and construction of structures incorporating protective systems
• Publications - research papers and other publications
• Research Team - faculty, staff, and students involved in protective systems research at Berkeley

This site and the PROSYS database are currently in the development stage, and considerable work remains to be done to broaden the scope of the information incorporated and the linkages among the various types of information. We encourage visitors to this site to provide feedback and suggestions for further information to be included.
