Development and Evaluation of Simplified Procedures for Analysis and Design of Buildings with Passive Energy Dissipation Systems - Revision 01
MetadataShow full item record
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 Safety Council, Technical Subcommittee 12, Base Isolation and Energy Dissipation, for the year 2000 update of the "NEHRP Recommended Provisions for Seismic Regulations for New Buildings and Other Structures." Topics presented in the report include development of extended damping coefficients for modification of response spectra for damping in excess of 5% of critical; development of relationships between elastic and inelastic displacement of yielding systems with energy dissipating devices; a study of displacement ductility demand in yielding structures with viscous damping systems; development of equivalent lateral force and modal analysis procedures for buildings with damping systems; and validation studies of the developed analysis procedures using 3- and 6-story structures with linear viscous, nonlinear viscous, solid viscoelastic and yielding damping systems.
