Steel Bracing

Different materials can be selected for the individual components. The following materials are available:

• Structural steel (S235, S275, S355, S450)
• Annealed steel (S275N to S460N)
• Thermo-steel (S275M to S460M)
• Weathering steel (S235W to S355W)
• High-temperature steel (S460Q to S460QL1)
• Hollow section, hot-finished (S235H to S355H)
• Hollow section, hot-finished, fine-grain (S275NH to S460NH)
• User-defined steel

Available systems:

• Truss with compression-slack diagonal struts
• Constant span lengths, a symmetrical division or individual span lengths

Cross-sections:

• Trusses:  I-sections as standard shapes or user-defined sections
• Posts: I-sections, circular, square and rectangular hollow sections as standard shapes or user-defined sections
• Diagonal struts: I-sections, circular, square and rectangular hollow sections, angular, round, and flat steel as standard shapes or user-defined sections

Supports:

• Hinged supports at the bottom chord of the bracing

• The wind loads are determined automatically based on the defined building geometry
• The determination of the wind loads depends on the specified location of the building
• Automatic determination of the stabilising loads either as uniformly distributed loads as per DIN EN 1993-1-1, 5.3.3 or as node loads in accordance with Petersen Stahlbau (Grundlagen der Berechnung und baulichen Ausbildung von Stahlbauten)
• The user can enter user-defined load cases in addition
• Automatic generation of the load case combinations
• Concentrated load (transverse) and line load (transverse) at the top and bottom chord

The program maps automatically all necessary combinations of actions in accordance with the safety concept set forth in Eurocode 0. Either the elastic or plastic cross-sectional resistance is verified. In this verification, the internal forces are determined in a first-order analysis with consideration of the applying stabilisation loads and the failure of the diagonal compression strut. For the diagonal tension struts, the cross-sectional resistance of the compression posts is verified. In addition, a stability verification as per DIN EN 1993-1-1, 6.3.1 is performed. The verification of the chord for the additional axial chord force is not supported in this software.
