Comparative analysis of designing wall panels with hole based on one-dimensional and two-dimensional computer models

[摘要] The operation of reinforced concrete wall panels with holes used in civil engineering has been studied. Under conditions of plane stress wall panels operate in vertical (qy) and horizontal (qx) evenly distributed loads conditioned by the own weight of the panels and pressure of the overlying overlap and covering structures. The effect of wind load on the building develops the flexural state of wall panels, i.e. loading the structures with the transverse evenly distributed load takes place. To study the stress-strain state of the above-mentioned structures, the work proposes a rod approximation in the form of a rod of a step-variable cross section, taking into account the presence of a hole in the body of the wall panel. Using the numerical finite-difference method there one solved the initial fourth-order differential equation for the compressed-bent state of the deformed rod. The results are presented in the form of the diagrams of transverse, axial and angular displacements, bending moments, longitudinal and shear forces diagrams. The results of the studies are of scientific and practical importance.
