✦ Synopsis

An updated Lagrangian formulation of the generalized conforming ¯at shell element with drilling degrees of freedom is derived based on the incremental equation of virtual work of a three-dimensional (3D) continuum for a purely geometric non-linear analysis of the space structure. While solving the non-linear equations, the Euler±Newton method and modi®ed Euler±Newton method are used in static analyses, and the modi®ed arc-length method and Newton arc-length method for post-buckling problems. A number of numerical examples are given to demonstrate the eectiveness of the proposed approach and programs.
