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 steel-truss combination truss monolithic test, another truss combination truss was selected as the shear connector for bending buckling and calculated according to the shear capacity formula of the bending buckling connector in the Chinese specification. Based on the test results, this paper analyzes the performance of the bent bar joints in the overall work, and shows that the use of the normative formulas in the combined truss is more conservative. Therefore, two formulae for the shear capacity of the bent bar joints that are suitable for the trusses without the plate truss are listed. , and lists the formulas for the shear capacity of anti-bending and buckling connections. The list is compared, and it is recommended that it be used in the non-plate toggle structure. It is suggested that when adopting China’s normative design for bending bar joints, the plate bracket should be set to meet the structural requirements.
