This video explains the P-delta (second order) analysis algorithm that operates under the hood of commercial structural analysis software such as etabs, staad, spacegass, strand 7, skyciv, midas and sap 2000 vs the simplified analysis method (by hand) that we covered. You will develop a solid understand on how linear elastic and nonlinear analyses are connected to solve a complex structural analysis problem, and solidify your understanding of the finite element analysis method to develop your own solver.
