Sažetak
The numerical model for the geometric and material nonlinear limit load analysis of steel space frames under large displacements is presented in this paper. A simple, global discretization using beam-column finite elements is preferred to a full, global discretization with 3D elements. The steel cross-section is discretized with 2D elements to apply the fiber decomposition procedure to solve the material and geometrical nonlinear behavior of the cross-section under biaxial moments and axial forces. A local discretization of each beam element is based on the comparative body model (i.e., a prismatic body discretized using brick elements, element by element, during the incremental-iterative procedure) allows determining the torsional constant of the cross-section under limited warping. The model implements well-known bending, lateral and torsional stability effects. For the large displacement analysis, an originally developed Null Configuration Model (NCM) is applied as an incremental application of the Total Lagrange - small displacement theory. A step-by-step procedure for the incremental loading of a follower load is applied. The numerical model has been implemented in a computer program for the practical engineering computation of the limit load of steel space frames. The practical application of the model is illustrated on presented examples.
