Pereira et alii, Frattura ed Integrità Strutturale, 50 (2019) 242-250; DOI: 10.3221/IGF-ESIS.50.20 247 Solution was performed considering both physical and geometric nonlinearities, using displacement control, with initial displacement increments of 0.05 mm, but these increments were automatically changed by the software to accelerate the solution in each model. R ESULTS AND DISCUSSION ig. 6 to 9 present the vertical load vs. displacement (parallel to the longitudinal direction of the column) curves obtained with each different methodology. The columns also had their strength calculated according to the prescriptions of the EN 1992-1-1:2004 [22]. Figure 6 : Load vs. displacement curves obtained with the four different methodologies for model E1. Figure 7 : Load vs. displacement curves obtained with the four different methodologies for model E2. Figure 8 : Load vs. displacement curves obtained with the four different methodologies for model E3. F
