| Title of the article | Bolt assembly for connecting thin-walled cold-formed profiles with a trapezoidal wall using continuous sleeves |
| Abstract. | Problem statement. To carry out a numerical study of the stress-strain state of a node of thin-walled cold-formed profiles with a part of a concave flat wall (trapezoidal) when installing solid bushings in the area where the profile wall and the sheet profile do not come into contact. Determine the nature of the stress distribution at the installation sites of the bolts using solid sleeves. Results. The main results of the work consist of a numerical study of a new structural solution of the bolt joint assembly and determination of its stress-strain state according to the calculation results in the «ANSYS Workbench» software package. Conclusions. The significance of the research results for the construction industry lies in the fact that the new constructive solution of the assembly using continuous sleeves allows eliminating the gap between the sheet gusset and the trapezoidal profile wall, thereby bolting in this place and improving the actual operation of the assembly. It should be noted that the design of the connection unit with the proposed solution for the installation of elements in the form of continuous sleeves allows saving steel by 20-30 %, in contrast to the strengthening of the site with sheet steel. |
