[摘要]通過分析基于概率抗震性能評估方法的技術(shù)框架,確定該方法的基本假定。基于典型鋼框架動力彈塑性計算結(jié)果的統(tǒng)計分析,證明基于我國規(guī)范設(shè)計的鋼框架結(jié)構(gòu)符合該方法的基本假定。因此,基于概率抗震性能評估方法適用于基于我國規(guī)范設(shè)計的鋼框架結(jié)構(gòu)的抗震性能評估,并采用該方法建立鋼框架結(jié)構(gòu)層間位移角風(fēng)險曲線,對鋼框架結(jié)構(gòu)達到“大震不倒”抗震目標的能力給予概率意義上的量化。

Probabilistic performance-based seismic evaluation of steel frame

Abstract:By analyzing the technical framework of probabilistic performance-based seismic evaluation method, the basic assumptions were determined. Based on the statistical analysis of dynamic elastic-plastic analysis result of typical steel frame, it is proved that China code-designed steel frame agrees with the basic assumptions. Therefore, probabilistic performance-based seismic evaluation method is adequate for seismic performance evaluation of China code-designed steel frame. According to the method, drift hazard curve of steel frame was established. The probability of ability steel frame reaching anti-collapse performance level under rare earthquake was quantified.
Keywords:steel frame; probabilistic performance-based seismic evaluation; drift hazard curve
