| 摘 要： | GB50010-2002《混凝土结构设计规范》关于单、双向板界限的条款规定比较模糊。本文仍采用简单条带法,通过分析荷载及弯矩在长、短跨方向的分配及随跨长比的变化情况,明确提出当按弹性理论分析时,宜采用长短跨长比为3作为划分单、双向板的界限。然后,从塑性铰线法设计双向板的基本方程入手,经分析讨论后得出当按塑性理论设计时,单、双向板的分界实质上是相对的,矩形板甚至正方形板究竟是单向板还是双向板,完全取决于配筋方式这一结论。最后,给出了双向板按单向板设计的建议。

| Abstract: | The update Concrete Structure Design Code is quite fuzzy about the one-way or two-way slab boundary stipulation.This article still used the simple strip method,through analysis load and bending moment in long and short span direction assignment and change situation along with span ratio,proposed explicitly if using elastic theory analysis,the ration of span should be adopted 3 as the division boundaries between single and two-way slab.Then starting from the basic equations of the plastic hinge,obtained that... |
