Flexural strengthening of reinforced concrete elements using external tie-rods

Abstract

The present study analyses the setup and computational methods of flexural linear reinforced concrete elements strengthening systems. Behavior particularities under exploitation of the reinforced concrete beam-tie-rods in trapezoidal system assembly are defined. The computational algorithm is supposed to start with the preliminary design of the trapezoidal tie-rods considering a criterion that assures the nomogram system’s optimal conformation. The preliminary design consists of Mathlab codes which provide the system’s optimal characteristics. The stress determination in the resulting system is undertaken through statically indeterminate computational procedures and the solution is given by mathematical relationships in Mathlab or by finite element modeling.
