The total weight of metal constructions: 780 ton. 

 

LEROY MERLIN Commercial Center is a group of one-storied heated rectangular multi-span structures that are interconnected and fastened; axial overall dimensions: 138х126.5m. The height to the bottom of supporting structures in the one-storied part of the main building is 7,05m. The height of attic overhead cover is 4,765 m. The overhead cover supported on the beam system is a reinforced concrete span, with 75mm metal corrugated sheet as a stay-in-place formwork. The covering is made of goffered steel sheets put over ledgers. Shallow pitch roof with the indoor water outlet. The column space is variable and longitudinally is equal to 6.2 m, 9.3 m and 18.6 m, transversely - 24 m and 6 m. The net of columns under the attic overhead cover is 6.5х9.3 and 4,5х9,3m.

 

The building frame consists of the columns rigidly mounted with the foundation, of the overhead cover beams rigidly mounted and pin-ended on the roof truss columns and secondary truss columns and of the covering beams. The ledgers made of hot-rolled channel bars bearing the covering goffered sheets are supported by the covering trusses and beams. 

The lateral stability of the building is assured thanks to the total operation on horizontal loads of the flat-topped frames, consisting of the frame columns pin-connected with the roof truss, as well as to the rigidly connected attic overhead cover beams; while the longitudinal load is guaranteed by the total operation of the vertical interconnections and of the columns rigidly restrained in the foundation. The vertical and horizontal connections provide the geometry control during the construction installation as well. The building designed shape stability is provided by the covering rigid disc consisting of the covering goffered sheets connected with ledgers, and with the attic overhead covering disc.

The column design: welded I-beams and hot-rolled channel bars. 
The attic covering beams design: welded I-beams.
The roof truss columns and secondary truss, ledgers, horizontal connections over the covering, and vertical connection design: twin angles.
