SUPER-LC 7.xx

Superpositioning Results of Different
RSTAB Structures (Construction Phases) 
The RSTAB add-on module SUPER-LC enables you to subsume construction phases when varying conditions of the model and of the actions are involved. Construction loads or temporary supports are not only relevant in bridge design but also have to be considered in many other ranges of structural engineering.
Features

  • Management of the RSTAB models according to the construction progress
  • Definition of the geometric boundary conditions for the single construction and operational conditions
  • Access to load cases, load groups and load combinations of all structures
  • Superpositioning of the various models by an envelope of all extreme results
  • Combination options according to these standards:
    •  DIN 18800:1990-11
    •  Eurocode
    • DIN 1045:1988-07
    • DIN 10451:2008-08
    • DIN 1052:1988-04
    • ÖNORM
    •  DIN 1055-100:2001-03
    • Serviceability (unscaled)
  • Tabular and graphical output of results
Input

A basic model is created. It is adapted according to the progress of construction work and saved each time under a new file name. Those different structural models are then used for the supercombination. The superpositioning can be carried out like for an RSTAB load combination.

By modeling various construction or operational conditions, the different geometric boundary conditions can be represented: It is possible to add or remove, for example, supports, members or elastic foundation to or from the model.

Superpositioning

When defining a new super combination, one of the integrated standards can be chosen. The partial safety coefficients are preset. It is also possible to create a new standard and to save it with the user-defined safety factors.

The combination criterion determines which load cases, load groups or load combinations of which model are to be considered. The actions can be scaled by factors and classified as "permanent" or "conditional". By defining "or" criteria, alternative examinations are also possible. Graphic representations make it easy to allocate the relevant models.

When determining the extreme values, SUPER-LC imports the results of the structures and combines them according to the combination criterion. In doing so, the results are compared on the basis of the node and member numbers.

Results

The maximum and minimum extreme values (the envelope) are displayed in tables and in the graphics. They can be integrated into the central printout report of RSTAB.

It is also possible to design the internal forces of super combinations in many RSTAB add-on modules.
