To　study　the　influence　of　transverse　spacing　and　different　arrangements　of　stud　connectors　on　structural　mechanical　performance,　ten　local　full-scale　model　specimens　were　designed　and　manufactured.　Transverse　bending　and　tensile　performance　tests　were　conducted　at　the　center　of　the　bridge　deck　support　and　the　cantilever　side.　The　results　indicated　that,　under　interior　side　curvature,　the　studs　were　subjected　to　compression　on　the　side　of　the　stiffener　and　tension　on　the　outer　side　of　the　web.　All　studs　on　the　outer　side　of　the　web　experienced　tensile　fractures　near　the　stud　head.　Under　cantilever　side　curvature,　the　studs　were　subjected　to　compression　on　the　outer　side　of　the　web.　Due　to　the　constraint　effect　of　the　stiffeners　on　the　upper　flange,　the　studs　on　the　side　of　the　vertical　stiffener　were　primarily　in　tension.　Under　the　same　transverse　arrangement　of　studs,　the　bending　and　tensile　bearing　capacities　under　cantilever　side　curvature　were　significantly　lower　than　those　under　interior　side　curvature.　For　a　given　unit　length　arrangement　of　studs,　when　four　studs　can　be　accommodated　within　the　flange　width,　it　is　advisable　to　evenly　distribute　the　studs　on　both　sides　near　the　web　to　prevent　detachment.　It　is　recommended　to　avoid　placing　studs　directly　above　the　stiffeners　and　webs.　When　designing　the　transverse　arrangement　of　studs,　it　is　suggested　to　use　four　rows　of　studs,　maintaining　a　ratio　of　0.15　between　the　transverse　spacing　and　the　width　of　the　upper　flange　of　the　I-beam.
