Calculation of diagonal deformation of the house

To calculate the voltage and deformation of the frame with filling, it is necessary to determine the width of the conditional slanting, the linear deformation of which (with a simple compression, calculated subject to the constant elasticity module equal to the initial tangential module of the elasticity of the filling material) is similar to the diagonal deform of the filling (established subject to the alternating module from stress). The calculation of diagonal deformation was developed by the authors to fill in concrete.

This calculation is carried out by the final elements in the following assumptions, the normal and tangent voltages in the contact surface are distributed along the triangle, the length of the contact with the column depends on the characteristic of the stiffness and is determined by the above ratios, the length of the contact surface with the crossbars is equal to half the span, the elasticity of the filling material of the filling changes in depending on the voltage (when calculating, the tangential module was accepted).

With an increase in the voltage, the value of the elasticity module decreases, which is manifested by changing the values of the relative deformations of the elements of filling in the direction of compressed slanting (from the maximum values in the corners of the magnitude of relative deformations are reduced towards the center of depreciation). At the same time, the width of the conventional strip of braces that have a constant everective module changes. Consequently, the width S will change with a change in the magnitude of the diagonal forces (decreases with an increase in the load).

The maximum width occurs with the initial stressful state of the diagonal forces, I am approximately equal, which is a diagonal force at the limit of destruction of the filling in the pressure, in which the fragmentation of the filling panels in the corners, rop -shaped, is fragmented. compressed slanting, when it is possible with sufficient accuracy when calculating the deformation of the filling to use in the entire range a constant initial tangential elastic module.
