Passive Energy Dissipation for Seismic/Wind Design and Retrofit

NCEER and the Earthquake Engineering Research Center at the University of California/Berkeley are presenting a series of short courses entitled Passive Energy Dissipation for Seismic/Wind Design and Retrofit. The 2?day course is designed to provide practicing structural engineers and design professionals with a basic understanding of the principles of energy dissipation devices and their design procedures. It will review the development, performance and application of these systems and present analysis and design procedures for their use. Content will include case studies of the implementation of passive devices to new and existing structures for both seismic and wind loads. Sessions will feature software used for dynamic analysis of structures with these protective systems in mind. Specifically, the course will cover:

Instructors will review the following systems in detail: yielding metal devices, solid viscoelastic devices, tuned mass dampers, tuned liquid dampers, friction devices, viscous and semi-viscous fluid devices, and shape memory alloy devices.

The course is being offered at the following locations:

An optional ?day field trip at the end of each course session will allow participants to visit sites where passive energy dissipation devices are being tested or implemented. In San Francisco, they will visit the Wells Fargo building and the testing facilities at the EERC laboratories. In Los Angeles, a trip to San Diego will allow course participants to view a U.S. Navy building presently being retrofitted with viscoelastic dampers. A nominal fee of $20 is being charged for the ?day field trip.

This short course series involves a number of individuals prominently involved in NCEER's long-standing program in structural control and is the first in NCEER's Professional and Continuing Education (PACE) program. Technical coordinators for the program are T.T. Soong (NCEER) and Andrew Whittaker (EERC). Other participating instructors include: Ian Aiken, Finley Charney, Michael C. Constantinou, Gary F. Dargush, James Kelly, John Mander and Andrei Reinhorn.

An early-bird registration fee of $575 is being offered, which includes instruction, course materials and refreshments.
