Experimental Study of Bridge Elastomeric and Other Isolation and Energy Dissipation Systems with Emphasis on Uplift Prevention and High Velocity Near-Source Seismic Excitation,

by  A. Kasalanati and M.C. Constantinou,

This report focuses on the design and construction of an isolator testing machine, the testing and modeling of prestressed isolators, and an experimental study of bridge elastomeric isolation systems with an emphasis given to near source high velocity seismic excitation. The experimental results for the prestressed isolators, non-isolated configurations, and bridge model isolated with low damping elastomeric bearings, high damping elastomeric bearings, low damping elastomeric bearings combined with linear viscous dampers, and low damping elastomeric bearings combined with nonlinear viscous dampers are provided in PDF format and can be downloaded.

Please note: These files are quite large. Though you can open them in your browser using the Adobe Acrobat Reader, they may take quite a long time to load and may crash your browser! Therefore, these files are also available via ftp.

"Getting" these files via ftp willl enable you to avoid some of the  difficulties encountered when attempting to open them and using a web browser. However, once you have downloaded these files to your hard drive, you will still need a copy of the Adobe Acrobat  reader to open them and read them.
