为研究中国规范《冷弯薄壁型钢结构技术规范》（GB 50018-2002）计算壁厚2 mm 以下钢板自攻螺钉连接抗剪承载力的适用性和钢板-非钢板单颗自攻螺钉连接抗剪承载力设计方法，对钢板-钢板、钢板-石膏板以及钢板-定向刨花板（OSB板）连接件共计34个试件进行了试验研究，分析了板材类型、螺钉端距等因素对连接件抗剪承载力的影响，并将中国规范、英国规范和北美 AISI S100-12规范计算结果与试验结果进行对比分析，最后提出钢板-非钢板单颗自攻螺钉连接抗剪承载力设计方法。研究结果表明：钢板-OSB 板、钢板-石膏板连接件破坏模式为 OSB 板与石膏板发生承压破坏，且具有明显的方向性；随螺钉端距的增大，试件抗剪承载力有所提高；中国规范 GB 50018-2002适用于壁厚2 mm以下冷弯薄壁型钢板自攻螺钉连接抗剪承载力的设计计算，且偏于安全。
為研究中國規範《冷彎薄壁型鋼結構技術規範》（GB 50018-2002）計算壁厚2 mm 以下鋼闆自攻螺釘連接抗剪承載力的適用性和鋼闆-非鋼闆單顆自攻螺釘連接抗剪承載力設計方法，對鋼闆-鋼闆、鋼闆-石膏闆以及鋼闆-定嚮鑤花闆（OSB闆）連接件共計34箇試件進行瞭試驗研究，分析瞭闆材類型、螺釘耑距等因素對連接件抗剪承載力的影響，併將中國規範、英國規範和北美 AISI S100-12規範計算結果與試驗結果進行對比分析，最後提齣鋼闆-非鋼闆單顆自攻螺釘連接抗剪承載力設計方法。研究結果錶明：鋼闆-OSB 闆、鋼闆-石膏闆連接件破壞模式為 OSB 闆與石膏闆髮生承壓破壞，且具有明顯的方嚮性；隨螺釘耑距的增大，試件抗剪承載力有所提高；中國規範 GB 50018-2002適用于壁厚2 mm以下冷彎薄壁型鋼闆自攻螺釘連接抗剪承載力的設計計算，且偏于安全。

In order to investigate the applicability of calculating the shear capacity of single tapping screw connection with sheet steel under 2 mm according to Chinese code Technical Code of Cold-formed Thin-wall Steel Structure (GB 50018-2002)and the design method of single tapping screw connection between steel plate and non-steel plate,a total of 34 specimens were tested in three series,which were distinguished by the connection forms,such as steel plate-steel plate connection,steel plate-gypsum wallboard connection and steel plate-oriented strand board (OSB)connection.Authors analyzed the influence of sheet material and the screw end distance, etc.for the shear capacity of single tapping screw connection and compared the calculation results with the test results according to Chinese code,British code and North American AISI S100-12 standard.Finally,the design method of shear capacity of single tapping screw connection between steel plate and non-steel plate was proposed.The research results show that the failure modes of steel plate-OSB connection and steel plate-gypsum wallboard connection are bearing damage in plate-gypsum wallboard and OSB which are both anisotropic.With the screw end distance increasing,the shear capacity of specimens is improved.Chinese code GB 50018-2002 is suited to calculate the shear capacity of single tapping screw connection in cold-formed thin-wall steel with sheet steel under 2 mm and the results are safe.
