Summary: Non-linear P-delta behaviour of three-dimensional frames with irregular plant geometry is studied, using a parametric variation of geometry and stiffness formerly chosen, by comparing results obtained with author’s developed software and with established commercial software. Using the exact total stiffness formulation of nonlinear geometric analyses in the developed software, allows surveying its degree of precision in selected calibration examples, as compared to the exact analytical results as well as to commercial software results. A parametric study of the critical load factor of asymmetric three-dimensional frames, un-braced and braced, permits to characterize their carrying capacity with respect to overall structural stability.
