| 摘 要： | 钢屋面结构中斜卷边的“Z”型薄壁型钢檩条通常在支座处相互搭接 ,设计时利用连续梁的分析方法获得构件的内力 ,为此构建了一个用梁单元和二力杆单元构成的力学分析模型 ,揭示了檩条在互相搭接情况下的内力传递过程 ,证实采用连续梁的分析模型即可较为准确地描述连续搭接的檩条的内力状况 ,并且可以按连续搭接的方式进行檩条的设计

| Abstract: | In the metal roofing system,Z|shaped purlins are lapped each other upon the roof rafters.Engineers design the purlins using continuous moment distribution.In this thesis,the writer introduces an analytical model,which is constructed with a series of beams and truss members,to show how the moment is transferred through the lapped connection.A detailed calculation shows the internal force and deflection of the model is similar as the one of a continuous beam.So the continuous beam method is suitable for analyzing the roof purlins. |
