Zusammenfassung:This paper develops a unified nonlinear analysis technique for two-dimensional structural frames. Any level of nonlinear effects can be rationally treated, and results automatically obtained to any specified accuracy. The procedure only requires minimum discretisation of the structure as a self-adaptive procedure is used to solve the member equations. The nonlinear solution techniques used enable either discrete equilibrium positions or the complete load-deflection response to be calculated.
