CALCULATION OF STATICALLY INDETERMINABLE STRUCTURES STRENGTHENED BY THE METHOD OF REDISTRIBUTION OF STIFFNESS

Abstract

The procedure is presented to calculate the effective of strengthening for the statically indeterminable structures reinforced by the method of directed redistribution of stiffness. The dependences by definition of load - carrying capacity of the strengthened structures situated in composite stress state are obtained. The getting results allowing to estimate degree of increase of load - carrying capacity of a strengthened structures at elastic-plastic deformations are pre-sented.
