MODELING OF THE STRESS-STRAIN STATEOF STRENGTHENED BEAM SYSTEMS

In the paper, the variation method of calculation of the loaded beam systems strengthened in the ways of increase of section of elements and change of the constructive and settlement scheme of structures by installation of additional elements is presented. Taking into account plastic deformations of influence of repair and mounting stresses on degree of increase of load-carrying capacity of strengthened statically indeterminable structures was researched.
