Structural Response to Long-Duration Earthquakes
The objective of the study was to estimate and assess structural demands that such large-magnitude, long-duration earthquakes might produce. The demands were determined using inelastic response-history analyses of single-degree-of-freedom models with load-displacement relations for steel (bi-linear) and for concrete (degrading stiffness). In the analyses, the models were subjected to ground acceleration histories for the postulated earthquakes, for previously recorded earthquakes, and for earthquakes with elastic spectra similar to those of the current design criteria. The response was quantified by maximum displacement, dissipated inelastic energy, and displacement cycle counts. Analyses were performed for structure vibration periods between 0.1 and 4 seconds and for structure lateral yield strengths between 12.5 and 50 percent of the structure weight.
