Original Abstract
The paper describes a complex approach to probabilistic design of precast structural members made form advanced cementitious composites. First, a series of material, small scale component tests have been conducted in collaboration between two laboratories. Based on these tests identification of fracture-mechanical parameters (and their statistics) for two concrete mixtures used for the production of precast structural members was performed. Subsequently, studies have been performed on (a) full scale pre-stressed concrete roof elements (b) ten scaled laboratory tested elements. Mentioned experiments served as basis for deterministic nonlinear modelling of precast members and subsequent probabilistic evaluation of structural response variability. Final results may be utilized as thresholds for loading of produced structural elements and they aim to present probabilistic design as less conservative compared to classic partial safety factor based design and alternative ECOV method.
