On the effect of longitudinal deformation on the parameters of the stress-strain state of the hingeless arch

The article studies the effect of longitudinal strains for two circuits of hingeless arch loading on parameters of its stress-strain state (SSS), depending on the two parameters of the arch design scheme, that characterize the degree of flatness of arch axis outlines and the extent of arch body massiveness. A significant dependence of the parameters of the stress-strain state (SSS) on the arch design scheme is established. Obtaining the numerical values of the analyzed variables is carried out in the MathCAD program
