Abstract

In this paper, the problem of bending a multilayered concrete rod of constant cross-section under quasi-static loads is considered. It is assumed that if the strain is below the elastic limit, the rod is deformed elastically, and if the strain is above the elastic limit, the rod is deformed nonlinearly quasi-elastically. It is assumed that the rod is in a uniaxial stress state.

The calculations are obtained for a hinged rod in the case that the neutral line coincides with the axis of the rod. The analytical ratios are obtained to determine the limit loads for various locations of the boundary between the elastic and nonlinear quasi-elastic deformation areas in the case when the number of layers is two. The ratios are presented for determining the boundary between these areas.
