Náhradní ohybová tuhost profilu P-28
Original language description
Large deformations of steel reinforcements can often occur in mines and underground objects. Behavior of these reinforcements is constitutively and geometrically non-linear. There are needs for operative analysis of such reinforcements. Software for thistask is being developed. The software uses beam computation model. The paper discusses computational analysis of steel arch reinforcement with P-28 type of a cross-section. There were analyzed the 3D finite element models with use of the ANSYS software.The material has been defined as elastic-plastic with multi-linear hardening. The results have been used for creation of so-called substitute bending stiffness. The substitute bending stiffness is defined in relation to the function of the normal forceand the bending moment of the beam model.
