【摘要】 针对钢管再生混凝土柱这种新型组合构件,进行了抗震性能设计的控制参数研究。引入了三水平地震设防水准。采用五档性能水准,给出了对应的破坏状态及宏观描述,并分别以水平位移角和损伤作为性能水准的量化指标。汇总了国内外47个圆钢管再生混凝土柱和36个方钢管再生混凝土柱的抗震试验数据,依据正态分布统计方法,确定了不同性能水准下的水平位移角限值;引入Park-Ang双参数模型评估钢管再生混凝土柱的地震损伤行为,对课题组的10个圆钢管再生混凝土柱和6个方钢管再生混凝土柱的累积损伤指标取平均值,确定了不同性能水准下的累积损伤指标限值。按照三水平地震设防水准和五档性能水准,建立了合理、实用的钢管再生混凝土柱的性能目标。更多还原

【Abstract】 The control parameters of seismic design based on performance performance were studied about the new combination component of recycled aggregate concrete filled steel tube columns. Earthquake fortification level of three stages was introduced. Five performance levels were adopted to give the corresponding failure state and macroscopic description. Horizontal displacement angle and damage were selected as performance level quantitative indexes. The seismic test data were collected including 47 recycled aggregate concrete filled circular steel tube columns and 36 recycled aggregate concrete filled square steel tube columns,based on normal distribution statistical methods,the limit of horizontal displacement angle was determined under different performance levels. Double parameter model of Park-Ang was introduced to evaluate the earthquake damage of recycled aggregate concrete filled steel tube columns. The limit of cumulative damage index was determined under different performance levels by the mean of cumulative damage index about 10 recycled aggregate concrete filled circular steel tube columns and 6 recycled aggregate concrete filled square steel tube columns.Reasonable and practical performance objectives of recycled aggregate concrete filled steel tube columns were established according to seismic fortification level of three stages and five performance levels.更多还原
