Hello Mykola,
I apologize for the inconvenence, but AutoPIPE does not have a location to input a specific Dynamic Load Factor (DLF). However there are 3 options to consider for applying a scale factor.
1. After performing an analysis on a model, select Tool> Combinations> Code/Noncode Comb tab(s), modify a load combinations. Note, a specific load cases can be scaled by opening the combination and changing the Factor, as shown below.
OR
2. To scale Static Seismic load cases in a specific location part of a model; select a node point / range of points, press Insert> Xtra Data> Point/Member Static Earthquake Scale Factor, enter the X,Y,Z Factor, press OK button. See AutoPIPE online help for details on this function.
OR
3. Response / Force Spectrum input files can be scaled when assigning a defined spectra file to a specific Response / Force spectrum load case:
