摘要(Abstract):

考虑受力蒙皮组合体试验的特殊性,对普遍采用的悬臂梁式加载方式进行了改进,提出沿对角线加载的方法。为研究跨越多檩条和少檩条的受力蒙皮体抗剪性能的区别,对连接件形式和间距、框架和檩条的形式和间距均相同的两组试件进行了对比试验。利用曲线拟合方法对试验数据进行了量化,得到了两组试件的抗剪刚度。结果表明,跨越多檩条的受力蒙皮结构抗剪刚度较跨越少檩条的有较大提高,承载力稍有降低。
Concerning the specialty of the testing of stressed skin diaphragm assembly,the current loading method of cantilever beam test is improved by the diagonally loading method.In order to investigate the differences of the shear behavior between the stressed skins spanning several purlins and few purlins,which have the same forms and spaces of the connections and purlins,comparing experiments are carried out.Using the curve fitting method,the test results are quantified.The shear rigidity of two specimens is gained.It shows that the shear rigidity of the diaphragm spanning several purlins is quite higher than that spanning few purlins,but the carrying capacity of the former is a little lower than that of the latter.
