Original Abstract

Methods of the design assisted by testing philosophy can be used as the suitable and applicable tools for the determination of material properties and design resistances of structural members or components, especially if no other tools are usable. The paper is focused on the application of the methods of the design assisted by testing for the determination of material properties of cement composites reinforced by fibres using mainly for the building façade claddings, but also as a part of load-carrying structures, according to our experiences for the slab of steel-concrete composite beams, for example. The methods of the design assisted by testing are based on the evaluation of the experimental results arising from the statistical and probabilistic approaches. The procedures for the determination of characteristic and design value of the material property is usable not only for usual cases of the large test number, but also for small or very small test number, where the test number, type of the property distribution and its statistical characteristics are taken into account. In the recent period also new structures and structural details have been developed and used in practice, so that many times the design using test results only allows determine the design resistances of structural members, details or parts. On that account it is important and interesting to deal with the problems of the design resistance evaluation not only from the viewpoint of the influence of the test number and statistic parameters of variables directly determining the design resistance value, but also from the viewpoint of the mathematical function form of the design resistance model, which can be significant for the resulting design resistance. On several particular examples, the standard procedure for the design resistance evaluation with respect to the test number, mathematical exactness and complexity of the resistance model and variability of the basic variables is shown.
