Click the ... button to the right to enter new or modify existing load combinations. (Refer to "Load Cases / Combinations")
Step : Specify the step for which the analysis results are to be produced. The Step is defined in geometric nonlinear analysis as Load Step, and additional steps are defined in the construction stages of bridges or heat of hydration analyses.
The Construction Stage applicable for the output of the construction stage analysis is defined in Select Construction Stage for Display or Stage Toolbar.
Displacement : Display the displacement of the model in contour.

Current Step Disp.
Produce the displacements pertaining to the selected step of the construction stage if a construction stage analysis has been performed.
Stage/Step Real
Disp.
Display the Real Displacements for each construction stage when the construction stage analysis is performed.
Real displacement is relevant only for construction stage analysis. To illustrate real displacement, a cantilever is constructed in 3 stages as shown below. Node 3 is activated at the stage 3, and the deflection δ33 occurs due to the self weight of the segment 3. But when constructing steel girders or PC girders, the virtual displacements δ31 and δ32 occur at the stage 1 and stage 2 respectively. Real displacement is the summation of virtual displacements, which occur before the corresponding node is even activated and net displacement, which occurs after the node is activated. Real displacement corresponds to the fabrication camber.
Batch Output Generation
