A computationally efficient method for the limit elasto-plastic analysis of space frames
A method for the first order step-by-step limit analysis of space frames is presented. The incremental non-holonomic analysis is based on the generalized plastic node method. The nonlinear yield surface is approximated by a multi-faceted surface. The solution of the linear equilibrium equation at each load step is obtained with the preconditioned conjugate gradient method.
