Mechanical stresses in building structures and dry friction - ways to improve the durability of architectural structures

ZhanyuJing,DmitriiBenin, VeraSnezhko,LubovVorona-Slivinskaya,IliaAksenov

In this work, the authors offer a new approach to the problem of structural strength of architectural constructions and buildings. The authors propose to circumvent the problem of the multiplicity and complexity of numerical methods of calculation by reformulating the problem in terms of the concept of dry friction. A large architectural structure is essentially a combination of solids in contact. Monolithic structures consist of reinforced material, filler and binder, moreover, even the highest quality structure cannot escape systems of developing cracks.In addition, the requirements for seismic resistance and heat resistance make it necessary to introduce gaps, flexible seams and other elements into the structure that do not allow one to consider the architectural structure as an undeformable solid. The proposed approach will allow a deformable body to be considered as a set of connected solids - building elements. Similar approaches in seismology make it possible to obtain reliable results. Reconfiguring problems through a thermodynamic interpretation of the problem of dry friction will radically simplify the mathematical models, more directly introduce empirical parameters (by means of simple and direct measurements, rather than model calculations with discussed accuracy).
