Predicting the Load-Carrying Capacity of Reinforced Concrete Structural Element

Original language description

The load-carrying capacity of structural elements manufactured from concrete or reinforced concrete can be determined via classic approaches formulated within the statics of structures and linear theory of elasticity. These methods, despite being incorporated in relevant regulations, can nevertheless suffer from reduced effectivity of the final design. In this context, more realistic prediction of the load-carrying capacity of structural elements is achievable via utilizing the nonlinear constitutive law in the numerical computation. Using a nonlinear material model to simulate the behavior of concrete structures is, however, confronted with the problem that consists in the set of unknown parameters related to the selected constitutive law. These parameters can be mechanico-physical or fracture-mechanical, and their values are eventually obtainable by applying inverse analysis methods to the experimentally measured data. One of these techniques is based on exploiting an optimization algorithm, which enables us to minimize the difference between the measured and computed load-displacement curves. The present paper characterizes the inverse identification of material parameters in relation to the Menétrey-Willam material model used in the performed fracture test and discusses the subsequent computation of the load-carrying capacity of a reinforced concrete element executed via the same material model.
