［摘要］通過對壓型鋼板采用自攻螺釘連接的受力蒙皮進(jìn)行剪切性能的試驗，探討了這類蒙皮的破壞模式和抗剪極限承載力，研究了板型、連接件布置和檁條間距等因素對蒙皮抗剪性能的影響，介紹了《歐洲蒙皮設(shè)計建議》(簡稱EUR)中此類蒙皮的抗剪強(qiáng)度和抗剪剛度的簡化計算公式。研究表明，按照常規(guī)施工做法的此類壓型鋼板，可以考慮一定蒙皮效應(yīng)；試驗結(jié)果與計算值的比較分析表明，EUR簡化計算公式可以較合理地評估蒙皮板的剪切性能，計算結(jié)果偏于安全，可用于我國的實際工程的蒙皮設(shè)計。

Abstract:Test program on the shear behavior of stressed skin diaphragm using profiled sheet connected by the self-tapping screws has been carried out. The effect on the shear behavior of shin diaphragm such as sheeting section, arrangement of fasteners and purlines is studied by analyzing the failure modes and shear captivities of the panel. The simplified design formulas are recommended, which are prescribed by the European Recommendations for the Application of Metal Sheeting Acting as a Diaphragm(EUR). It is proved that the diaphragm effect of the profiled sheet made by the current construction is good and can be considered. The test data are compared with the results acquired by the EUR formulas. The results show that the EUR formulas are relatively safe for calculating the shear behavior of this kind of diaphragm and can be used for the design of cold-formed steel diaphragm in our country.
Keywords:self-tapping screws; stressed skin diaphragm; shear behavior
