压型钢板-混凝土组合板的承载能力受混凝土和钢板交界面剪切-黏结强度的控制。剪切-粘结破坏时,混凝土与钢板的界面滑移对组合板的承载特性有重大影响。现行组合楼板设计与施工规范的规定未考虑界面滑移效应的影响,由此可能导致设计结果不够安全。为揭示组合板剪切-黏结破坏的实质,在试验研究和有限元分析的基础上,基于欧洲规范的规定,分析了界面滑移及端部锚固栓钉对组合板承载特性的影响。提出了简支板和端部锚固组合板挠度计算的相关建议,可供工程设计人员参考。
壓型鋼闆-混凝土組閤闆的承載能力受混凝土和鋼闆交界麵剪切-黏結彊度的控製。剪切-粘結破壞時,混凝土與鋼闆的界麵滑移對組閤闆的承載特性有重大影響。現行組閤樓闆設計與施工規範的規定未攷慮界麵滑移效應的影響,由此可能導緻設計結果不夠安全。為揭示組閤闆剪切-黏結破壞的實質,在試驗研究和有限元分析的基礎上,基于歐洲規範的規定,分析瞭界麵滑移及耑部錨固栓釘對組閤闆承載特性的影響。提齣瞭簡支闆和耑部錨固組閤闆撓度計算的相關建議,可供工程設計人員參攷。

The loading behavior of composite slabs with profiled steel sheetings is affected by the shear bond strength be-tween the concrete and the steel deck .And it’s influenced significantly by the interface slip between the concrete and the steel deck in the case of shear bond failure .However ,the influence of interface slip on loading behavior is not considered in current codes for the design and construction of composite slabs ,which means unsafe results maybe deduced .To reveal the essence of shear bond failure ,according to previous experimental and finite elemental study ,based on the specifica-tions of Euro codes ,influence of interface slip and end-anchorages on the loading behaviour of composite slabs was ana-lyzed .The suggested values for the deflection of simply-supported slabs and slabs with end-anchorages were proposed , which could be used for engineering application .
