COMPUTER SIMULATION OF FAILURE OF CONCRETE STRUCTURES FOR PRACTICE 

Non-linear analysis of concrete structures became a novel design tool. It employs the power of computer simulation to support and enforce the creativity of structural engineers. Although it is frequently used in research and development its potential for engineering practice has not been yet fully discovered. In the new design standards for concrete structures, such as Eurocode 2 (1992), the non-linear behaviour of concrete is described by a uni-axial stress-strain diagram. However, this is only a fraction of the available knowledge of material models and theories discovered and validated by research. The finite-element-based failure analysis can take advantage of rational and objective theories such as fracture mechanics, plasticity and damage mechanics. It makes possible a “virtual testing” of building structures under designed loading and environmental conditions. The implementation of these advanced methods and techniques introduces new possibilities for the engineer, not only in research and development but also in practical design. Computer simulation is a modern tool for optimisation of structures, which can contribute to better economy in design.
