中文摘要：
使用PVDF涂层建筑膜材制成的结构,在承受外载荷情况下,力学行为非常复杂。在本文中,重点研究其单元结构在承受外载荷情况下的力学性能。首先,对PVDF涂层建筑膜材进行拉伸试验,测定其在常温和低温环境下膜的拉伸力学性能参数。然后,以制成的三角框架结构膜单元为对象,在常温条件下,从有限元分析和实际加载试验两方面计算得出结构单元在均布载荷下的位移、应变和应力分布。最后,对其进行强度验证,得出采用膜单元构建大型建筑是安全的结论。试验方法和结果可以应用于膜建筑结构的设计。
英文摘要：
The mechanical behavior of architectural structure made up of PVDF-coated architecture membrane,is very complex under exterior loading.In this paper,the mechanical capability of PVDF membrane under exterior loading was studied.Firstly,tensile experiment of PVDF-coated architecture membrane was conducted to obtain its tensile mechanical parameter under normal and low temperature environment.Secondly,through the method of finite element analysis and actual loading experimentation in the membrane cell with the...
