J. Navrátil et alii, Frattura ed Integrità Strutturale, 39 (2017) 72-87; DOI: 10.3221/IGF-ESIS.39.09 74 For reinforcing steel, we assume stress-strain diagram with a horizontal top branch given by EN 1992-1-1 [4], provision 3.2.7, with following parameters: f y = 465 MPa, E s = 200 GPa, ߝ su = 20 ‰. The resulting stress-strain diagram for reinforcing steel used for the analysis is illustrated in Fig. 3. Figure 1 : Geometry, cross-section, and the loading of RC column. Figure 2 : Stress-strain diagram of concrete used for the analysis. Both the results of numerical analysis and experimental data are presented in [2] and they are compared with IDEA StatiCa results, see Fig. 4. Horizontal displacement at the top of the analysed column is investigated. Both material and geometrical nonlinearity is taken into account. Consistently with the assumptions no post-critical behavior was analyzed in case of NLA.
