Abstract
The deformation method of calculating the strength of elements in the normal to the longitudinal axis of the cross sections is presented. According to (STB) EN 1996-1-1-2008 (Eurocode 6), the general regulations of calculation of stone elements, including reinforcement stone elements, correspond to the conditions of application of the deformation method of calculation of durability of normal sections. This method allows to reflect more faithfully the work of normal sections and to describe their tensely deformed condition (TDC) at any stage of the application of load. At the same time the deformation method of calculation of normal sections of stone elements has not yet found application in design. Comparison of the results of experimental data with the calculated (with the help of the deformation method) values of breaking loads of stone elements without reinforcing, with longitudinal and mesh reinforcing has been executed. The average value of the calculated difference is 7%.
