stiffness. For this purpose, a failure strain of 11‰ was assigned
to the textile instead of the average failure strain of 12‰ determined
experimentally. The assigned failure strain is still within
the range of the dispersion of the tensile tests results of the strain
specimens. The corresponding curve progressions are shown in
Fig. 18b. Compared with Fig. 18a it can be noticed that the failure
moment values hardly change whereas the calculated deflections
decrease and further approximate to their measured counterparts.
The summary of the failure moments and deflections is shown in
Table 4 and graphed in Fig. 19a and b. Smaller slab deformations
are obviously detected on stiffer textiles. A notably good accordance
between the test and the calculation can be found for the
failure moments (tolerance
