\\ The two primary means for including [P-Delta|kb:Geometric nonlinearityP-Delta effect] effect in [nonlinear|kb:Nonlinear] analysis include: # For each [load combination|kb:Load combination], create a nonlinear analysis [case|kb:Load case] which includes the P-Delta geometric-nonlinearity parameter. \\ \\ # For the gravity loads anticipated, create an Initial P-Delta Analysis [case|kb:Load case] which includes the P-Delta geometric-nonlinearity parameter, then consider all other analyses as linear while using the stiffness matrix developed for this one set of P-Delta loads. h1.
