By comparing the above 2 images, you will find：
The axial force from Sofistik does’t change from CS11 to CS15, while it decreases in RM Bridge (34XXkN in CS15 verse 36XXkN in CS11)
According to Sofistik verification manual:
The time dependent losses are calculated, considering the reduction of
stress caused by the deformation of concrete due to creep and shrinkage, under the permanent loads.
The axial force in the beam is the negative value of the tensile force in the tendon. Since the tensile force in the tendon decreases due to creep and shrinkage, why the axial force keeps the same in Sofistik?
Thank you. The stress in the beam does decrease with time. Unfortunately 7000 loadcases only shows stress in the beam, there is no internal forces in 7000 loadcases.
To get the deformation UZ you need LC 4024.
AQB works purely at member cross-section level, so the generated “load cases” only contain results for this. For example, strains or residual stresses (for the latter, see chapter 2.4 in the manual). But no results for nodal displacements in space, etc.
These “real” element-related results are stored in the load cases 4xxx (and 5xxx) for the time history calculation; the residual stress load cases 6xxx etc. are only taken into account in these calculations.
(This does not apply to QUAD-element-models, as all redistributions are determined directly with ASE due to the “lack” of AQB. However, modeling is more difficult overall and not everything may work.)
