Equilibrium Analysis of Pin-Jointed Steel Structures under Large Variations of Configuration

Abstract:

In the paper an equilibrium analysis of pin-jointed steel structures is described. The attention is focused on the non-linearity problem that characterizes this type of steel structures under large displacements. A matrix method is developed, starting from a balanced and congruent configuration. Firstly, the analysis is conducted on the single bar; the, the behaviour of the global structure is analysed through the re-assembling and the final non-linear relationships between the variation of loads and the configuration are identified in order to proceed to the iterative solution path.
