Geometric and Material Nonlinear Behavior Evaluation of Steel Moment Frames by Stability Functions

Computer enhancements make it possible to combine the theory of plasticity and sustainability known as advanced analysis. In this paper, the structural capacity diagram of a imperfections in the PAAP software using the advanced analysis. It was determined that the maximum reduction in load capacity was due to imperfections in the displacement of 0.20 m and at 7.88%. The effect of local buckling phenomenon was also examined with the help of changes in the software. The maximum reduction in load capacity for 1 and 2-storey frames was 2.90 and 1.6 times, respectively.
