Theoretically, this connection in relation to a shift and bending could be carried out using an absolutely supple infinitely small layer, which has a constant thickness in height. This layer can provide the trigger of the contacting fibers of neighboring plates similar to the assumption accepted for approximate calculation of the walls with continuous rows of openings.
The coherence of the structure is ensured using the aforementioned imaginary ties and the shifting forces acting along the crossing lines of the median surfaces of individual (flat) walls.
The functions of the shifting forces are determined from the conditions of equality of normal stresses (except for some cases of calculation when taking into account the effects of changes in volume) or deformation of the contacting fibers of neighboring walls. As unknowns, you can choose the total shifting forces, reinforced concrete from which the wall structure is made, behaves as a completely elastic homogeneous mass (the Law of the Hook) of the cross -section of all elements (and not only the horizontal section of the entire wall) during deformation remain flat; The influence of deformations of the shift of the supports between the rows of openings is not taken into account; Weakened areas (with openings) are considered as stripes of homogeneous material, the static work of which replaces the local effects of jumpers between the openings.
The rigidity of this conditional strip (layer) within the height of one floor is equivalent to the stiffness of the corresponding jumper between! openings. Static values of jumpers that arose during the bend of the wall are obtained in the form of continuous functions. Consequently, the wall is approximately behaving as a multilayer design (discrete-contental model), consisting of layers with various mechanical properties, fictitious forces that replace the effects of jumpers between the openings, ensure the coincidence of the shape of the deflection curves between the rows of openings.
