On the influence of geometrical non-linearity on the low-angle arches mode of deformation
Peculiarities of the deformation-based analysis of low-angle elastic arches have been considered. The algorithm for numerical realization of integral quadratures of analytical equilibrium equations for low-angle elastic arches has been developed. The computational nucleus of the algorithm has been realized using the MathCAD software package, while the user’s interface has been developed in the С++ Builder programming environment. Both the calculation results of a case example and numerical analyses into a set of parabolic elastic arches realized with the help of the authors’computer programme DrarCAD, are given to prove the necessity for the geometrically-deformed calculation model to be taken into account in the analysis of the arches in question.
