Experimental Study of Seismic Isolation Systems with Emphasis on Secondary System Response and Verification of Accuracy of Dynamic Response History Analysis Methods
This combined experimental and analytical study provides an assessment of the validity and accuracy of analysis methods commonly used for seismically isolated structures, emphasizing secondary system response, contemporary ...
Assessment of Performance of Bolu Viaduct in the 1999 Duzce Earthquake in Turkey
This report describes the impact of the 1999 Duzce, Turkey earthquake on the Bolu Viaduct, a 2.3-km long seismically isolated structure, which was under construction, but essentially complete, when the quake occurred. The ...
Development and Evaluation of Simplified Procedures for Analysis and Design of Buildings with Passive Energy Dissipation Systems - Revision 01
This report presents the development and evaluation of simplified methods of analysis and design for buildings with passive energy dissipation systems. The work was conducted under the auspices of the Building Seismic ...
Scissor-Jack-Damper Energy Dissipation System
This report describes an energy dissipation system configuration that extends the utility of fluid viscous damping devices to structural systems that are characterized by small interstory drifts and velocities. The geometry ...
Evaluation of Accuracy of Simplified Methods of Analysis and Design of Buildings with Damping Systems for Near-Fault and for Soft-Soil Seismic Motions
The effect of near-field and soft-soil ground motions on structures with viscous-damping systems was examined. Damping modification factors for damping ratios up to 100% of critical were obtained for sets of near-field ...
