Parametric Studies of Intra-Modular Connections Stiffness
The article is focused on the study of the stiffness of intra-module connections of stacked modules buildings with corner columns. A review of literary sources devoted to this issue has been carried out. It was revealed that the vast majority of the compounds considered by the researchers are semi-rigid according to the classification of Eurocode. Therefore, within the article, data is provided on parametric numerical studies of the rotational stiffness of the used types of nodes with different parameters to establish the boundaries of rigid joints of a crossbar with a column of modular buildings. Within the study, five types of intra-module connections were considered: without stiffeners, with vertical stiffener, with horizontal stiffeners. The main variable parameter for nodes with a vertical stiffener was the height of the stiffener. For nodes with horizontal stiffeners, the variable parameters were the width and thickness of the stiffener, as well as the material of the main elements and welding. Based on the results of numerical studies of the parameters of rotational stiffness of intra-module connections, it was found that the high strength materials could slightly increase the rotational stiffness of joints; rigid nodes with vertical ribs have a lower material consumption compared to nodes with horizontal ribs; nodes with horizontal ribs have more increased load carrying ability.
