Abstract
According to the situation that Chinese "Earthquake Resistant Design Code" ( GB50011-2010) does not rule the expression of vertical acceleration response spectrum, this paper collected hundreds of strong earthquake records in United States to study the influence of the factors such as seismic environment and structure damping ratio on the spectral ratio ( V/H). The authors selects some influencing factors which has a great impact on the spectral ratios and the regularity is good, including site conditions, epicentral distance and structural damping ratio. Based on genetic algorithm (GA) programming, the global optimum fitting results were researched. The fitted spectral ratio with impact of site condition as the datum spectral ratio is taken. Simultaneously, the impact of epicentral distance and damping ratio, was carried on the revision to the datum spectral ratio, thus the suggestion type of the spectral ratio under various earthquakes environment was established. Finally, the horizontal acceleration design response spectra was stipulated by current seismic design code of China and multiplied by the suggestion type of the spectral ratio from corresponding earthquake environment, then the suggestion type of the vertical acceleration design response spectra from this earthquake environment is obtained.关键词
