Szukana fraza: [Abstract = "The paper presents exemplary static equilibrium paths of an element strengthened while under load. A steel\-concrete composite beam was analyzed. The study discusses the effect of strengthening method, initial load values, welding stress, concrete shrinkage and introduction of additional control of distortion state on the course of static equilibrium path. Results calculated in numerical FEM simulation were verified with experimental data and were found to be consistent."]
