Suvorov A. - An overview of the possibilities of nonlinear deformation model in analyzing the formation and development of the nagel effect c. 70-75


Abstract: This article reviews the possibility of application of nonlinear deformation model in studying the nagel effect. The nagel effect is the ability of armature to transmit the force perpendicular to its axis. This effect occurs in terms of the phenomenon of slip of the two edges of an inclined crack. And this slip is impeded, along with the force of engagement along theadges of the crack, by the intersected by this crack longitudinal reinforcement. And as a result, nagel’s deformation can be defined as the difference in deformations of two blocks separated by an inclined crack. The phenomenon of nagel effect is quite complicated and requires the introduction in the algorithm of its description of the nonlinear parameters of the environment of its formation and development. The nonlinear deformation model is optimally suited for determining the nature of the distribution of forces in the zone of transverse bending of the reinforced concrete element. The stress-strain state (SSS) of the oblique section requires more computational dependencies due to the complexity of describing the biaxial stress state in this zone. Modern regulatory techniques for the calculation of sloping sections have in their composition many empirical and semi-empirical dependences, which do not allow to fully estimate the SSS of the oblique section. The provisions proposed in this article represent a new perspective of the development of nonlinear deformation model and will allow making a contribution to the development of normative algorithms for calculating the cross sections in the zone of transverse bending.
