Resumo(s): | Steel Fiber Reinforced Self Compacting Concrete (SFRSCC) was developed and applied on the manufacture of structural façade panels composed of a grid ribbed system covered by a layer of 30 mm thickness. Panel prototypes of this structural system were tested using loading configurations that promote the flexural and the punching failure modes in order to assess the benefits of fiber reinforcement to the flexural and shear resistance of thin SFRSCC structural systems. A smeared multi-fixed crack model, implemented into a FEM-based computer program, was used to simulate the deformational behavior of the tested panel prototypes up to their failure. The fracture parameters characterizing the SFRSCC post-cracking behavior were obtained from inverse analysis, using the data derived from three point notched beam tests. The punching failure mode was well captured by adopting a softening diagram for both out-of-plane shear components. |
