Construction of a production and storage hall

The 6,300m2 production and storage hall was designed as a steel frame structure – restrained steel columns and articulated trusses supported on them. The structure consists of three aisles with spans of 18.00m, 24.00m and 33.00m respectively. Two cranes are foreseen in each aisle. For the 18.00m aisle – 2x6t crane, the 24.00m aisle – 2x6t crane, the 33.00m aisle – 2x8t crane. The calculations assume tandem operation of the cranes. Due to the production and storage nature of the facility, a usable height of ~8.60m was assumed, with a ridge height of ~11.60m.

Static assumptions: restrained columns, gable trusses articulated on columns, purlins in a continuous multi-span arrangement, roofing – trapezoidal sheet metal. In order to stiffen the system, the truss in the 33.00 m aisle is designed as a frame, bringing the bottom chord to the columns. Additional stiffness of the structure is provided by bar bracing (tendons), braces and portal bracing in the form of square pipes.

The building was founded directly on the footings. Due to poor ground conditions and the presence of embankment soils, soil replacement was carried out using cement stabilisation technology on site, and the soil layer was replenished by bringing in stabilised soil on site.

User benefits:

By using the automatic selection of climatic loads, time was saved on the substantive aspects of the model. The profile optimisation function enabled the selection of optimum profiles both during the initial selection of elements and during the final polishing of the analysis.

The modules for the dimensioning of reinforced concrete elements function very smoothly and intuitively. The possibility of quickly defining the soils allows us to check several calculation scenarios that enlarge our database of created geological profiles, which we often use in other projects.

In addition, the function of exporting data to the external programme Idea StatiCa for detailed analysis of nodes was particularly used in this project.

Thanks to the programme’s functions and capabilities, both the foundations (geometry, use of reinforcing steel) and the steel structure, for which we achieved a steel utilisation of 51kg/m2, have been optimised.
