STRUCTURAL MODELLING AND MECHANICAL BEHAVIOUR OF STEEL FIBRE REINFORCED CONCRETE. FIBRE REINFORCED CEMENTS AND CONCRETES: RECENT DEVELOPMENTS. PROCEEDINGS OF AN INTERNATIONAL CONFERENCE HELD AT THE UNIVERSITY OF WALES, COLLEGE OF CARDIFF, SCHOOL OF ENGINEERING, UNITED KINGDOM, SEPTEMBER 18-20, 1989

Estimates of mechanical behaviour of steel fibre reinforced concrete (SFRC) can be based on a structural model of a partially-oriented fibre dispersion. Anisometry and segregation, recorded in quantitative image analysis approaches to such composites, are incorporated in the model. It is shown that anisotropic mechanical behaviour in splitting tension mode is in agreement with the theoretical predictions. The same theoretical concept is extended to the boundary zone in which the reinforcement ratio in a cross-section is experimentally shown to decrease. It is demonstrated that model predictions and image analysis results closely match each other. Rupture will take place in a significantly under-reinforced cross-section - the weakest chain link - unless macrocracking is forced to take place under the load, as in four-point bending and splitting tensile modes. An approximate solution is given to the associated structural problems. The best approach is offered by computer-simulation. Such a system has been developed for that purpose. This way of tackling structural problems will shortly be introduced.(A) For the covering abstract of the conference see IRRD 827953.
