| 摘 要： | 利用大型软件ANSYS实体单元系统，分析了大跨度叠层空腹桁架转换结构在竖向荷载作用下楼板整体弯曲问题。由于楼板的整体弯曲在楼板中产生不可忽视的附加应力，与叠层空腹桁架类似的大跨度结构的现浇混凝土楼板设计应考虑整体弯曲的影响，并提出了相应的设计建议，可为相关结构分析和设计提供参考。

| Abstract: | For large-span laminated open-web trussed transfer structure, the whole bending properties of floor under vertical loading were studied using ANSYS, a commercial software. As in no way to omit the additional stress resulted from the whole floor bending effect, it should be considered in the design of large-span structure which similar to laminated open-web truss. Some suggestions were offered which may be helpful for the structure design and analysis. |
