heal.abstract	Non-linear solution methods are investigated for the analysis of shell and spatial structures based on limited memory quasi-Newton updates. Under the proposed implementation the preconditioned truncated Lanczos method is used for the solution of the linearized problem in each non-linear iteration. The complete factorization of the stiffness matrix is avoided and large-scale problems can be solved efficiently both in terms of computing time and storage. The non-linear iterative scheme is properly modified to account for loading variation inside the increment in order to trace post-critical equilibrium paths.	en
