The paper presents essential steps in the development of numerical computational model of destructive test of prestressed T-shaped concrete girder. First, a series of material, small scale component tests have been performed 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 with a span width of 30.00 m and a height of 0.50 m to 0.90 m, made of C50/60 and different reinforcement layouts, and (b) twelve scaled laboratory tested elements with a length of 5.00 m and heights from 0.30, 0.45 and 0.60 m in order to capture size effects in the shear bearing performance. |
