This paper concerns an approach to model the ledger-stand joints of modular scaffolds. Based on the analysis of the working range of the ledger (represented by a linear relationship between load and displacement). two models of the ledger-stand joint are analysed: first - with flexibility joints and second - with rigid joints and with a transition part of lower stiffness.
