摘要
在讨论各种玻璃采光顶支承结构的基础上,首先对由桁架和系杆组成的玻璃采光顶支承结构在各种荷载工况下的结构进行分析,具体分析结构的内力、挠度以及材料的使用效率,并讨论此类结构构件截面的选用;其次,考虑玻璃与支承结构的共同工作,对结构进行整体的分析和比较;最后利用规范公式以及考虑几何非线性的有限元分析两种方法,对带孔采光顶玻璃进行应力和挠度计算,并分析孔边距对于玻璃应力分布的影响,可为结构设计提供依据。
Based on the discussion on all kinds of sustaining structures of glass roof, the supporting structure of glass roof composed of trusses and bars under all load cases is analyzed firstly with finite element software, including internal force and deflection of the structure, the using rate of the material and the cross - section selection of this type of structure component. Then the performance of lighting roof in cooperation with glass panels is studied by numerical simulation The paper also provides the calculations on stress and deflection of the glass roof with holes and shows the stress distribution of glass affected by hole - borders, by the standardized formula and the finite element method considering the geometric nonlinearity.
