Structural solution

The frame consists of columns, trusses, purlins and bracing. Spatial rigidity is achieved through rigid connections between all elements.

Hybrid frame

The load-bearing columns are made of hot-rolled carbon steel — they carry the main load of the two-storey building. Every other element of the frame — trusses, purlins and bracing — is made of cold-formed LSTK profiles 100, 150, 200 and 250 mm high, produced at our own plant.

Columns and beams

Columns along the internal axes are made from square and rectangular hollow sections to GOST 30245-2003. The beams are I-sections to STO ASCHM 20-93.

Steel grades

Grades S245, S280 and S350 to GOST 27772-2021 were used. The grade was selected according to the load on each specific element rather than applied uniformly across the frame.

Load calculation

Static analysis was performed in the SCAD software suite. Loads were taken to SP 20.13330.2016: nominal wind pressure 0.3 kPa, design load on the roof frame 2.1 kPa — accounting for the snow load of the Atyrau region.

Corrosion protection

All LSTK profiles are galvanized. Welding and gas cutting of galvanized profile on site is not permitted — connections are made with self-drilling screws only, so the zinc coating stays intact. Any damaged areas are restored with protective coatings to SP 28.13330.2017.

Fabrication and installation

Work was carried out to GOST 23118-2019 and SP 70.13330.2012. Permissible deviations from design dimensions follow Annex B of GOST 23118-2019. Column bases were fixed with Sormat S-Ka 12×128 mm anchors.
