The calculation was performed for several values of the normal force F (200 kN, 400 kN, 600 kN, 800 kN, 900 kN, 1000 kN, etc.) with the eccentricities at the top and the bottom of the column, respectively, e t = e b = 0.024 m until the collapse was reached (normal force of 1225 kN in this case). It is obvious that the results obtained by the IDEA StatiCa solver and data stated in reference [8] are closely similar. The values of ultimate resistance F max and corresponding horizontal displacement w Fmax at mid-length of the column obtained by the IDEA StatiCa solver are compared with the data stated in reference [8], see Tab. 2. Ref. [8] IDEA Difference F max [kN] 1212 1225 δF max = – 1.07 % w Fmax [mm] 12.0 10.9 δw Fmax = – 9.17 % Table 2 : Comparison of results.
