[提要] 進(jìn)行了6榀全注芯配筋混凝土小砌塊抗震墻的水平反復(fù)荷載試驗，分析了墻片的高寬比、軸向壓力、水平和垂直鋼筋對抗剪承載力的影響，對《抗震結(jié)構(gòu)設(shè)計規(guī)范》（GB50011-2001）中抗剪承載力計算公式的應(yīng)用提出補(bǔ)充建議，并綜合國內(nèi)已有的數(shù)據(jù)分析得出這類墻體的抗剪承載力簡化計算公式。
[關(guān)鍵詞] 混凝土小型空心砌塊 灌芯砌體 抗剪承載力Six fully-grouted reinforced concrete block seismic walls are tested under cyclic horizontal loads. The influences of height width ratio, axial load, horizontal and vertical bar on the shear strength are discussed. Some recommendations in application of the formula in the Code for Seisrnic Design of Building ( GB5001 1-2001 )are presented. Based on the analyses of existing test results, a simplified formula for evaluating the shear bearing capacity of these walls is proposed.
Keywords: small-sized hollow concrete block; grouted masonry; shear bearing capacity
