[摘要]針對(duì)鋼管再生混凝土柱這種新型組合構(gòu)件,進(jìn)行了抗震性能設(shè)計(jì)的控制參數(shù)研究。引入了三水平地震設(shè)防水準(zhǔn)。采用五檔性能水準(zhǔn),給出了對(duì)應(yīng)的破壞狀態(tài)及宏觀描述,并分別以水平位移角和損傷作為性能水準(zhǔn)的量化指標(biāo)。匯總了國(guó)內(nèi)外47個(gè)圓鋼管再生混凝土柱和36個(gè)方鋼管再生混凝土柱的抗震試驗(yàn)數(shù)據(jù),依據(jù)正態(tài)分布統(tǒng)計(jì)方法,確定了不同性能水準(zhǔn)下的水平位移角限值;引入Park-Ang雙參數(shù)模型評(píng)估鋼管再生混凝土柱的地震損傷行為,對(duì)課題組的10個(gè)圓鋼管再生混凝土柱和6個(gè)方鋼管再生混凝土柱的累積損傷指標(biāo)取平均值,確定了不同性能水準(zhǔn)下的累積損傷指標(biāo)限值。按照三水平地震設(shè)防水準(zhǔn)和五檔性能水準(zhǔn),建立了合理、實(shí)用的鋼管再生混凝土柱的性能目標(biāo)。

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.
Keywords:recycled aggregate concrete filled steel tube column; seismic fortification level; performance level; quantitative criterion; performance objective
