摘要
为了为我国某公铁两用桁梁结合梁大桥确定栓钉规格、栓钉承载力设计值，本文通过大量试验，研究了国产２２、２５和１３检钉（１４ＭｎＮｂｑ母材、Ｃ５０混凝土）的ｐ－ｕ曲线、按极限承载力以及混凝土配筋率、栓钉间距、反复加载。
In order to select the shear connectors and determine their design strength for a certain Bridge composite girders, the ultimate limit states of φ22, φ25and φ13 studs(14MnNbq steel, C50 concrete)and the influence on ultimate strength of studs of reinforcement ratio of concrete slab, interval of studs and re load unload were studied.
