摘要
本次钢－砼组合桁架整体测试中另一榀组合桁架选用了弯筋作为剪力连接件，并按我国规范中弯筋连接件抗剪承载力公式计算．本文根据测试结果分析了弯筋连接件在整体工作中的性能，表明在组合桁架中使用规范公式比较保守，因此列出两个适用于无板托组合桁架的弯筋连接件抗剪承载力公式，并列出了反放弯筋连接件抗剪承载力公式，列表进行了比较，建议在无板托格构式组合结构中采用．并建议采用我国规范设计弯筋连接件时，应设置板托以满足构造要求．
In this whole test of steel-concrete composite structures,bendbar connectors were used on another composite truss. The shear-bearing capacity of them was calculated according to the State Standard. The performance of bendbar connectors in the whole test was analysed basing on the test results. It is indicated that the fomula from the State Standard was conservative when uued on composite truss Without bracket bracing. So, three formulas, which were put forward and compered in form, were recommended to be used in composite truss without bracket bracing.Bracket bracing is recommended in order tO meet the need of construction while designing bendbar connectors according to the State Standard formula.
