“…Based on the results of the work done, it can be concluded that the formula for the initial critical load by N.P. Puzyrevsky (2) leads to a strong overestimation of the allowable pressure, which does not correspond to the fulfillment of condition (1).…”

“…The issue of ground strength is of paramount importance in the practice of designing structures in determining their dimensions that satisfy the conditions of safety, durability and economy [1][2][3][4]. In modern practice, the ground strength is usually described by the Mohr-Coulomb condition according to Coulomb CA (1776), which in the formula interpretation has the following form:…”

“…To search for an analytical solution, it is necessary to introduce some simplifications that will make it possible to obtain a formula that is convenient for practical use: the use in the calculation of points that, when a uniformly distributed load P is applied, will be the first to cease to correspond to condition (1). Such points are the corner points of the foundation, the stresses in which are determined by the determination of the largest and smallest principal stress with ignoring the intermediate principal stress in accordance with the strength condition (1) the task ν = 0.5. This coefficient is taken exclusively for effective stresses from an additional uniformly distributed load P. This assumption greatly simplifies the determination of stresses σ zp , σ xp , σ yp , τ xy , τ zy , τ zx , since when using ν = 0.5 these values will not depend on the ratio of the dimensions of the foundation slab.…”

Despite the fact that the Mohr-Coulomb theory of strength appeared more than a hundred years ago, many authors are still conducting research in accordance with the recommendations to find optimal solutions to practical problems. From the Coulomb-Mohr theory, a huge number of methods for solving applied problems were formed, for example, the initial critical load, which is useful for research in the article. This formula is no longer new, but despite this, it is still the object of research. The authors of this article consider the case of the assumption, applying it when issuing a formula for the initial critical load. Based on the initial critical load, a formula for the design soil resistance was obtained, which is still regulated by codes and standards in the field of design. The authors reflect the main ependencies that appear in the calculation of the stress-strain state in soil mechanics. Based on these dependencies, the amount of allowable stress is revealed, under which the condition of linear deformability will be satisfied. The authors have shown that the proposed formula for any stability parameters will correspond to the Mohr-Coulomb limit state condition. The conclusion of the article compares the effect of the formula obtained by the authors and the recipe of the formula obtained by N.P. Puzyrevsky.

“…Geogrid is geosynthetic material widely used in embankments (Badanin and Kolosov, 2012), slopes, and retaining walls (Ibrahim, 2021). As a geotechnical structure, the grid itself and the reinforced soil are topics of research (Aleksandrov et al, 2016;Polyankin, 2020).…”

A damage-softening model for a reinforced soil interface is proposed based on the trilinear model of a reinforced soil pullout interface, aiming at the softening phenomenon of the geogrid reinforced soil interface during the pullout process and considering the damage softening of the reinforced soil interface during the pullout process. The damage variable factor D is introduced, and it is assumed that D is a function of the interface displacement. The two-parameter Weibull distribution function is used to express the damage evolution law of the reinforced soil interface. Based on the basic control equation of the reinforced soil interface, the calculation model of the stress state of the geogrid at different stages under the pullout load is deduced. To verify the accuracy and applicability of the model, the prediction results of the model are compared with the test results and the ideal elastic–plastic model, hyperbolic model, elastic–exponential softening model, and the damage softening model based on a lognormal distribution function proposed in this paper. The distribution of interfacial shear stress is studied, and the influence of parameters at each stage is analyzed. The results show that in the elastic stage, with the increase of shear stiffness, the maximum shear stress at the interface increases, and the curvature of the curve also increases, while the elastic modulus is the opposite. In the softening stage, with the increase of softening length, the peak value of the curve moves to the free end. In the residual stage, the shear stress increases from the drawing end to the free end and tends to the residual stress. The research results are in accordance with the actual situation and can be applied to reinforced soil engineering.

The motion of strong earthquakes causes nonlinear deformation and damages to the structure. For structural systems of buildings, domestic and European (EC8) regulation apply algorithm of seismic design based on reference linear-elastic methods that are carried out in two phases. Phase I includes determination of dynamic characteristics of structure, which are then used in phase II for calculation of seismic effects. In this study, parametric analysis of influence of dynamic characteristics of structure was done on multiple numerical examples, according to domestic and EC8 regulations and comparison of results.
