# Construction Stages - Results#

## Basics#

The following description is valid for a construction process with stage numbers ranging from 1 to 999 (extension for stage numbers > 999: see final section).

The *Construction Stages* task creates several sets of loadcases.

Loadcases 4000-4999:

here the loads and results of the individual construction stages until the “present” stage (which is denoted by the last 3 digits of the loadcase number) are summed up

these loadcases show the actual state of internal forces, displacments, etc. in each construction stage

example: loadcase

*4060*shows the sum of loads/results of all construction stages up to (and including!) the present stage*60*

Loadcases 5000-5999:

show the difference of loads and results of a construction stage to the previous one

example: loadcase

*5060*shows the difference of loads/results/displacements from the previous stage (e.g.*55*) to the present stage*60*(LC 5060 = LC 4060 - LC 4055)

Loadcases 6000-6999:

are used to store the eigenstresses from creep and shrinkage for beam elements

Note

These are only calculated if module AQB is used for the calculation of creep and shrinkage (default for beam elements; see also tab *Control Parameters*).

Loadcases 7000-7999:

are used to store the linear elastic stresses of beam elements in the present stage

example: loadcase

*7060*shows the stresses in construction stage*60*resulting from the sum of internal forces (loadcases from*5000*to*5060*) and eigenstresses (loadcases from*6000*to*6060*)

Note

The stresses are only computed if the option *Stress results for all stages* is selected in tab *Control Parameters*

Loadcases 15000-15999:

are used to store the primary (statically determinate) effect of prestress for the individual stressing stages

Loadcases 16000-16999:

are used to store the secondary (statically indeterminate) effect of prestress for the individual stressing stages

## Additional results for special settings#

### Precamber analysis#

For the precamber analysis the precamber is included in the deflections of loadcases 4000-4999. For checking purposes there are also loadcases created without precamber. These are stored in the loadcases 14000-14999.

### GPC-seperated Loadcases#

For the special option of GPC-separated loadcases (see *Separation of GPC loads for construction stages: Removing temporary supports* in tab *Control Parameters*) the additional loadcase sets
11000-11999, 12000-12999, 13000-13999 are created (for further information see section 2.13.1 in the manual of module CSM).

## Extension for stage numbers > 999#

If construction stages with numbers > 999 are included in the analysis the above concept is expanded for higher numbers:

LC number for max. stage number < 999 |
LC number for max. stage numbers > 999 |
