Salajka et alii, Frattura ed Integrità Strutturale, 39 (2017) 88-99; DOI: 10.3221/IGF-ESIS.39.10 94 The displacement, strain and stress fields at the discrete points of the models were obtained by the calculations on the L1, L2, S1 and S2 models. Considering the scope of the data, the results were mainly processed in a form of graphs and figures. L1 Wall The cyclic response solution on the L1 model with the preload 807 kN (including the girder and the concrete block) was compared with the values obtained from the test. Excitation function of time history lateral displacement is shown on the Fig. 9. The responses of the lateral displacement on the surface in the centre of the concrete beam obtained from the measurement and by the calculation are presented in Fig. 9. The lateral displacement obtained from the measurement is represented by a red dashed line and the lateral displacement of the same variable obtained by the calculation is shown by a blue line. In Fig. 10, there is a representation of the reaction force dependence on the lateral displacement for the both cases of the experiment and the calculation.

L2 Wall During the solution of the L2 wall the preload was 1,613 kN (including the girder and the concrete block). The results of the comparison are in Figs. 11 and 12. The mode of “step-by-step” destruction and relevant stages of the walls after testing are shown in Fig. 13.
