Calculation of reinforced concrete plates with hole at long-term loading

The article is devoted to improving the calculation of reinforced concrete slabs, taking into account the deformation under prolonged load and spatial design work. As a reference for the calculation of the impact study is taken shape, size and location of the holes in the circuit boards of fracture, as well as the proposed expression for calculation of deflections for one of the cases. Use of the deformed scheme allows to develop a settlement unit, approximating to the actual calculation of the plates, as well as to achieve a significant reduction in materials. We consider the continuous slab, supported on a loop and a plate having a square hole in the center.

For practical basis for calculating the deflection plates, it was created in the design scheme of the complex system Ing + Gen_3dim 2014. (paper)
