| Title of the article | Development and research of new types of joints of thin-walled elements |
| Abstract. | Currently, there is an intense increase in the production of thin-walled cold-formed profiles of galvanized steel and lightweight structures with their application: trusses, frame designs and mesh domes. The peculiarity of this construction is that their design solutions envisage the use of bolted connections at the nodes. The main problem in the use of thin-walled cold-formed profiles with connection bolt is low bearing ability of the compound to collapse. At the moment there are several ways to increase the strength of such joints. For increase the bearing capacity of nodal connections is assumed to use the limb of the end and install fixing elements (bolts) between the bent parts, which increases an area of the compound working by collapse twice. Further increases area of collapse can achieved by installing additional intermediate parts. To confirm the effectiveness of the proposed solutions were carried out numerical and experimental studies of the nodal connections. Studies have shown that the proposed ways to improve the bearing capacity of thin-walled elements of nodal connections by bending their ends enhances the carrying capacity of more than twice. However, it should be noted that the presence of bent sections and reinforcing sheet metal parts alters the character of VAT compound in comparison with the traditional. Therefore, further studies are required of the compounds, in particular, from the perspective of assessing their deformability and local stability of the bent portions. |
