董春敏，周淼（河南理工大學(xué)土木工程學(xué)院, 焦作 454000）［摘要］通過14根矩形截面框架柱在斜向水平荷載作用下的受剪試驗(yàn)，研究其斜向受剪承載力的計(jì)算方法?；趩蜗蜩旒塥补澳Ｐ?，建立了一個(gè)雙向桁架拱模型。為了驗(yàn)證該計(jì)算模型的可行性，利用此方法對(duì)本試驗(yàn)的14根框架柱及其他文獻(xiàn)中的16根框架柱的斜向受剪承載力進(jìn)行了計(jì)算。試驗(yàn)結(jié)果和計(jì)算值的比值表明，基于雙向桁架拱模型推導(dǎo)的計(jì)算公式可以安全估算矩形截面框架柱斜向受剪承載力，滿足工程需要。［關(guān)鍵詞］雙向桁架拱模型； 雙向受剪承載力； 矩形截面框架柱； 斜向水平荷載中圖分類號(hào)：TU375.3文獻(xiàn)標(biāo)識(shí)碼：A文章編號(hào)：1002848X(2013)12004304Research on oblique shear strength of concrete frame column with rectangular cross sectionDong Chunmin， Zhou Miao（School of Civil Engineering, Henan Polytechnic University, Jiaozuo 454000, China）Abstract:To investigate the calculation method of oblique shear strength of rectangular frame column, a total of 14 specimens under oblique horizontal loads were test. A bilateral trussarch model was proposed developed on the base of the unilateral trussarch model. To verify the feasibility of the bilateral trussarch model, the oblique shear strength of 30 specimens among which 16 specimens were made by other researchers were calculated. The comparison between test results and calculations shows that the developed model is safe to evaluate oblique shear strength of rectangular frame columns subjected to oblique loads, which satisfies the engineering requirement.Keywords:bilateral trussarch model; bilateral shear strength; rectangular frame column; oblique horizontal load*河南省教育廳自然科學(xué)研究計(jì)劃項(xiàng)目（2009A560007），河南理工大學(xué)博士基金項(xiàng)目（B20087）。作者簡(jiǎn)介：董春敏，博士，副教授，Email:dongchunmin@126.com。參考文獻(xiàn)［1］王威, 薛建陽, 章紅梅, 等.框架結(jié)構(gòu)在汶川512大地震中的震害分析及抗震啟示［J］.世界地震工程, 2009, 25(4): 131135.［2］GB 50010—2010 混凝土結(jié)構(gòu)設(shè)計(jì)規(guī)范［S］.北京：中國(guó)建筑工業(yè)出版社，2011.［3］董春敏.不等肢配箍矩形截面框架柱斜向受剪承載力試驗(yàn)研究［D］.天津:天津大學(xué),2007.［4］Comité Eurointernational Du Béton.
