An Evaluation of Seismic Energy Demand: An Attenuation Approach, by Chung-Che Chou and Chia-Ming Uang (#2000/04). As a first step in the development of an energy-based procedure for seismic design and verification, establishing seismic demand in the form of absorbed energy spectra for an inelastic single-degree-of-freedom system was the main objective of this research. The absorbed energy, not the input energy of hysteresis energy, was selected as the key demand parameter because it is not only related to the yield strength but is also directly attributed to the damage to the structure. The report is available from the National Information...
