【摘要】 近年来耗能减震装置在桥梁领域应用越来越广泛,为了从宏观的角度评价其抗震效果,对国内外30年来10次较大地震132座梁式桥震害资料进行统计分析,并运用回归分析的方法计算出转化到相同标准下的各次地震的梁式桥标准破坏率,并由此建立梁式桥震害—时间曲线,得出近年来梁式桥耗能减震装置抗震效果的统计评价结论。更多还原

【Abstract】 This statistic analysis is based on the data of 132 bridges earthquake disasters which caused by 10 earthquakes occurred in last 30 years.Regression analysis is adopted and a standard seismic damage rate-time curve id achieved,which can show us distinctly the effect of the energy dissipation structures set on the girder bridges recent years.更多还原
