Calculation of Limit Loads for Ground Anchors "Atlant"

The article considers methods for calculating “Atlant” anchors under the action of a tensile axial load, bending moment, and shearing force. The selection of the anchor cross-section depending on the value of the axial tension load is based on the requirements for conducting control tests with a one-and-a-half-fold excess of the calculated load. Taking into account the requirement that plastic deformations should not occur in the anchor rod during testing, we conclude that the calculated value of the tensile axial load should not exceed 60% of the force at the required yield strength. The calculation of the anchor under the action of a shearing load shows that the value of the maximum tangential stresses exceeds the value of the average tangential stress by 1.84–1.98 times, depending on the size. The plot of tangential stresses in a cross section has a quadratic character, similar to the plot of tangential stresses in a round section, square section, or I-beam. The generalized results of calculations are summarized in the final table, which will serve as a reference when designing anchors for various force effects.
