Resumo(s)
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.
