| The purpose of this article is to present issues related to the modeling of a modular scaffolding node, which is the weakest element of the scaffold structure. Due to the nature of work and complexity of the construction, it is necessary to take account of the phenomena associated with friction and contact. This combination of a node is not a constant connection, so it is necessary to take into account the changes in the node (looseness). The transfer of force in the node is carried out through a small area which is resulting the plastic deformation. The proper numerical modeling of the node requires laboratory testing to track the behavior of the node as well as information of the material characteristics of the node elements. The numerical model accurately mapping behavior of the node, allow loading force to the nodes in any ways and any number of elements (max 8). This is an alternative method for determining the capacity of the nodes in relation to the more expensive laboratory tests. |
