METHOD FOR CORRECTING REPRESENTATIVE DISPLACEMENT WAVEFORM, AND METHOD FOR EVALUATING RESIDUAL SEISMIC PERFROMANCE OF BUILDING

摘要

A method for correcting a representative displacement waveform comprises: a step for finding a performance curve characterized by reflecting a predetermined frequency band of a measured acceleration waveform of a seismic wave and not reflecting frequency bands other than the predetermined frequency band according to the frequency analysis of the measured acceleration waveform; a step for finding an approximate expression of the performance curve; a step for applying the measured acceleration waveform of the seismic wave to the approximate expression to find a virtual displacement waveform; a step for performing frequency analysis on the virtual displacement waveform to find a displacement waveform for correction which reflects at least some of the frequency bands other than the predetermined frequency band; and a step for correcting a representative displacement waveform serving as a basis for the performance curve according to the displacement waveform for correction.
