四边简支大型钢筋混凝土圆孔多孔板,由于在一个方向上存在孔洞,实质上是一种双向受力的正交异性板。此种板在一定条件下,还需要考虑孔洞的剪切变形的影响,这样计算更加合理,但是求解更为复杂。为了适应实际工作的需要。本文不仅阐明了不考虑孔洞剪切变形时的内力和挠度的简明计算公式,而且也给出了考虑孔洞剪切变形的内力和挠度的简明计算公式,及其适用条件。
The four-sided simply supported large reinforced concrete round hole porous plate, due to the presence of holes in one direction, is essentially a two-way stress orthotropic plate. Under certain conditions, the plate needs to consider the influence of the shear deformation of the hole. This calculation is more reasonable, but the solution is more complicated. In order to meet the needs of practical work. This paper not only clarified the concise calculation formulas for the internal forces and deflections without taking into account the shear deformation of the hole, but also gave a concise formula for the internal forces and deflections taking into account the shear deformation of the hole and its applicable conditions.
