This structural report is an structural calculation concerning a trusssystem produced by the company
GLOBAL TRUSS. The truss types go by the names F32. The structural report is the basis for the
certification by TÜV based on EN 1999-1.
The truss system is part of a "modular construction system" with the different truss lengths
500mm, 1000mm, 1500mm, 2000mm, 2500mm, 3000mm, 3500mm, 4000mm, 4500mm and 5000mm.
The Trusses consist of an upper and a lower main chord (round tube 50 x 2mm). The trusses also
consist of welded diagonal bracings (round tube 20 x 2mm).
The distance between the system lines of the mainchords is 24 cm.
The trusses are connected with couplers consisting of female fittings, connectors and bolts.
The allowable loads are listed in tables (see chapter 6).
The verification of the single parts is done according the safety concept of EN 1990 with a partial safety
factor of the loading side of 1.50 for payloads.
For applications which can be calculated on the basis of other codes, the partial safety factors can be
adjusted (for example temporary structures acc. EN 13814, yF = 1.35 for payloads).
To use the resulting allowable loads with British Standard (BS) and ANSI, the allowable loads listed in
tables have to be multiplied by 0.85.
1.4 Geometrie und Belastung
Geometry and Loadings
Als Belastung werden folgende Lastarten untersucht /
the following loadcases are taken into account
Gleichlast vertikal
uniformly distributed load (UDL)
Einzellast in Feldmitte
Single-load in 1/2 point
Einzellasten in den Drittelspunkten
Single-load in 1/3 point
Das Eigengewicht der Traverse beträgt ca. 2,5 kg/m.
The selfweight of the truss is approx. 2,5 kg/m
