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	description
3970- 3997	3970- 3997	Comparison load cases - cast in one stage
4000 - 4999	40000 - 49999	Total construction stage displacements and forces (without prestress losses from creep and shrinkage)
5000 - 5999	50000 - 59999	Difference displacements and forces
6000 - 6999	60000 - 69999	AQB eigenstresses from creep and shrinkage incl. prestress losses
7000 - 7999	70000 - 79999	Sum of (linear-elastic) stresses incl. prestress losses from creep and shrinkage
15000 - 15999	150000 - 159999	Primary effect of prestress
16000 - 16999	160000 - 169999	Secondary effect of prestress
