INCREASING OF THE LOAD-CARRING CAPACITY IN THE STRENGTHENED LOADED STRUCTURES

In article the variation method is presented to calculate the stress-strain state of structures strengthening without withdrawal from the exploitation. The procedure is presented to determine the strengthening effectiveness on loaded beam structures with taking into account elastic-plastic works of material. On the basis of the stated method, the computer program is made and it allows to simulate the strengthened construction model work and to estimate its stress-strain condition at various stages with taking into account the deformations and the stresses which have an effect during the strengthening
