Load combination factors

In the load combination process, Tekla Structures uses partial safety factors and, for example, reduction factors on load groups to create load combinations.

The partial safety factors needed in the limit state design are:

  • Unfavorable partial safety factor in the ultimate limit state (γsup)

  • Favorable partial safety factor in the ultimate limit state (γinf)

  • Unfavorable partial safety factor in the serviceability limit state (γsup)

  • Favorable partial safety factor in the serviceability limit state (γinf)

Depending on the codes you use, you may need to use other combination factors. For example, the Eurocode contains three reduction factors0, ψ1, ψ2). Reduction factors exclude the impractical effects of simultaneous loads.

You can use values for load combination factors that are building code specific or user-defined.
