【摘要】 Ｔ型、检钉和该文反放弯连接件是系列研究之一、二和之三．反放弯地连接件在格构式试件上作推出试验，属国内外首次．文中分析工作机理和破坏形态，导出抗剪承载力公式，试验值与理论值吻合较好，约为正放弯筋的５０％．建议在有反向水平剪力的组合桁架等格构式组合结构中采用．更多还原

【Abstract】 The first of the serial researches is about T-connectors[1],the Second is about Welded-Stud Connectors[2]and this paper about abend bar Connectors laid reversely in latticed structure is the third of the Serial researches.The push-out tot about bend bar Connectors laid reversely in a lattice specimen is made first home and abroad.In this paper,the working mechanism and destroying-form of band bar Connectors laid reversely are analysed,the formula of shearbearing Capacity is infered and the test values,Which are about 50 percent of bend b3r Connectors laid normally,tally better with the theoretic values.So the formula Should be recommended to be used in Composite lattice structures including Composite truss provided that there is horizonhorizontal shear in Oppsite diection in thse strutwres.更多还原
