（1 哈爾濱工業(yè)大學(xué) 150090； 2 中國地震局工程力學(xué)研究所 哈爾濱 150080）[提要] 通過6片砌塊墻片恢復(fù)力試驗(yàn)及國內(nèi)100多墻片試驗(yàn)結(jié)果的對比分析，總結(jié)出構(gòu)造柱與芯柱對墻體抗震性能的影響程度，兩端設(shè)置構(gòu)造柱的砌塊墻在地震作用下構(gòu)造柱對墻體承載力與變形的貢獻(xiàn)要好于兩端為芯柱的情況；芯柱設(shè)置靈活，中部芯柱的抗震作用強(qiáng)于兩端芯柱作用。建議采用將構(gòu)造柱與芯柱結(jié)合設(shè)置的方案，即在墻體兩端設(shè)置構(gòu)造柱，中間設(shè)置芯柱，該項(xiàng)措施能發(fā)揮構(gòu)造柱與芯柱的各自優(yōu)勢，且利于施工，將使多層約束配筋砌體達(dá)到更好的抗震效果。

Six restoring-force experiments has been made, more than 100 walls experimental results were analysed and it was found that block walls with constructional columns performed better under seismic action than those with core columns when both were placed at the end of the wall. We also found that the core columns placed in the middle of wall perform better than those placed at the end of wall. So we suggest that constructional columns be placed at the end of the wall and core columns in the middle to obtain the best aseismic effect, for this measure can promote the advantages of constructional columns and core columns respectively and facilitate construction as well.
Keywords: concrete block; aseismic behavior; constructional column; core column; restoring force experiment
