DEVELOPED NUMERICAL MODELS Investigated Hall Structure
Figure 1. Investigated frame structure
The base of the current investigation is a real frame structure manufactured by the Rutin Ltd, shown in Figure 1. This is a typical one module industrial frame with duopitch roof. The span is 19,0 m, the distance between the frames varies between 6,0 - 6,8 m. The eave height of the structure is 5,9 m with the peak height of 9,36 m. The roof slope is 20°. The roof and the wall systems are also covered by thermo-isolated cladding system. The secondary bearing systems (purlins and girts) are manufactured from cold-formed steel sections. The beams and columns of the internal frames are made from welded I-girders with tapered webs using steel grade of S355J2. The frame has pinned column base joints and fixed peak and beam-to-column bolted joints. The bracing system is made from tie rods using diameters of Ø16- Ø24 mm and from tubes having dimensions of Ø76,1*2,9 mm - 101,6*3,6 mm. The fire requirements for the analysed structure are relative high coming from the function of the building. The main bearing system (internal frames and bracing system) is classified in the category R45, and the secondary bearing elements and the sheeting are classified into the category R30. The executed and currently presented numerical simulations and the developed joints models refer to this existing structure.
