SIMPLE EVALUATION INDEX FOR STRUCTURAL DAMAGE OF HIGH-RISE REINFORCED CONCRETE BUILDINGS DUE TO LONG-PERIOD STRONG GROUND MOTION

抄録

Simple evaluation of the degree of structural damage suffered by high-rise RC buildings after being subjected to strong ground motions is extremely important. For a large number of high-rise RC residential buildings for which strong-motion measurements or observations of microtremors before and after earthquakes have not been carried out, we developed a benchmark indicator allowing simple characterization—based on pseudovelocity response spectra for strong-motion records measured at ground points close to the building, as well as re-created waves and other data—of peak inter-story drift ratio values expected in a future major earthquake.
