Numerical Simulation of Reinforced Concrete Beam with Utilization of Elasto-plastic Material Model of Concrete
Original language description
Design of concrete structures in accordance with standards may suffer from less effectiveness of a final design. More realistic simulation of behaviour of structure can be achieved by incorporation of nonlinear material model within numerical simulation of given problem. However, this approach is connected with several difficulties. First of all, the utilization of nonlinear material model is confronted with problem of existence of material parameters that are not often known in advance. Second, the introducing reinforcement into finite element model is complicated by the choice of the correct element type and the correct bond between elements of both meshes. First of the above mentioned problems can be handled with by applying an inverse analysis based on utilization of optimization techniques. Such process of the inverse identification is based on the comparison of the experimental and numerical load displacement curves and minimization of the difference between them. The problem of the modelling of reinforcement can be resolved in more possible ways. The article shows the solution with simple truss elements that are modelled in according to finite element mesh of the concrete beam.
