顺肋简支加肋矩形板的弯曲问题

BENDING PROBLEM OF RECTANGULAR STIFFENED PLATES WITH SIMPLY SUPPORTED EDGES ALONG DIRECTION OF STIFFENERS

本文研究了考虑中面应变效应的顺肋简支加肋矩形板,具有弱抗扭开口截面肋时的弯曲问题,导出了全部位移及内力的解析式。文中对于应用该结果计算有关工程问题的数值例题进行了讨论。本文解答较之Huber理论更为完善,并且形式较简洁。

Considering the effect in the middle plane, in this paper the bending problem of rectangular plates stiffened by ribs of open section that have little torsional resistance with simply supported edges along the direction of stiffeners is researched. All analytical formulas of both displacements and internal forces are derived. By using the results a calculating exam ple to treat engineering problem is discussed. The solution with more simple form of the paper is better thart that of Huber's Iheory.
