Building modules

Options G and H of CEDRUS-6


With the building modules CEDRUS enters the third dimension by stacking CEDRUS-slabs. The generated building models feature graphical checks, mass extracts, calculation models for top-down analyses of vertical and horizontal loads and three-dimensional frame models for earthquake analyses with STATIK-6.



Option G

With the aid of option G it is possible to generate a geometric building model from CEDRUS-slabs. A direct benefit of this approach are easy visual checks of the generated building and mass extracts ordered by various criteria as well as a top-down analysis of vertical loads. This way the import loadings which are needed for the structural analysis of the storys are available directly. This option is basis for the option H which provides further calculation models.


Geometric building model

  • Contains all geometric data of a building and the material properties of each structural element.
  • The input is based on CEDRUS slabs according to the base module.
  • CEDRUS slabs can directly be used as storys or as master storeys for generating multiple storeys of same types.
  • The building is a result of stacking slabs at specified levels.
  • Slabs with translated and rotated geometry can be handled like in the case of two buildings based on the same parking garage or in the case of of stepped buildings.
  • The graphical output of the entire building or of arbitrarily defined partial systems in different formats allows easy visual checks
  • By extracting lists of mass (areas, volume mass) from the slabs, walls and columns of the entire building an overview of the main building's data can be obtained quickly.

Top-down analysis of vertical loads

  • Fully automized according to the stacked slab model (The loads at the bottom of the walls and columns are determined for each storey and transferred to the next load bearing storys.)
  • Subsequent to the top-down analysis the floor slabs can be analyzed and the reinforcement can be designed.


Option H

The option H is based on the option G and offers further calculation models. Top-down analyses of horizontal loads (wind, earthquake,...) can be carried out, masonry walls can be verified and frame models for earthquake analyses using STATIK-6 can be generated.


Top-down analysis of horizontal loads

  • Honrizontal loads can be imposed on the membrane of each sorey.
  • Lateral forces can automatically be generated.
  • As in the case of vertical loads the top-down analysis is carried out with the stacked slab model. The loads are subjected to the walls and columns with respect to their stiffnesses by fulfilling the state of euqilibrium and are transferred to the next story.
  • Each wall can individually be configured in order to bear forces horizontally or not.

Verifying masonry walls

  • Masonry walls can automatically be verified for numerous combinations of loadings (composed of vertical loads, wind loads, earthquake loads,...) according to the Swiss design code SIA 266.
  • The verification is handled by the program MURUS-6. For this purpose it is automatically called with all necessary input data (requires a licence of MURUS-6).
  • For each wall the compliance factor is computed by MURUS-6 which is the result of a limit state analysis in which the vertical loads are constant and the horizontal loads are variable.
  • The results can directly be checked at any time in detail by calling MURUS-6 manually with an automatic data transfer.

Generating frame models for earthquake analyses using STATIK-6

  • In most cases Cubus considers spatial frame models to be most capable for earthquake anlyses as they are required according to SIA codes.
  • For that reason a complete frame model for earthquake analyses using STATIK-6 can be generated by the buildung module.
  • The generation process of the model can be configured in several ways. Either a modell purely consisting of cantilever walls without taking into account any stiffness of the slabs or a frame model taking into account downstands and plate strips can be generated. It is also possible to join wall segments to pillars and to define walls which do not bear loads horizontally.
  • Beside the structural data the loadings and mass are also transferred to STATIK-6 so that an analysis can be started right away.
