Scaling Response spectrum with equavlient static with ETAPS API

Scaling Response spectrum with equavlient static with ETAPS API

Scaling Response spectrum with equavlient static with ETAPS API

I am trying to change the scale factor of response spectrum to be 100 % of base reactions of equavlient static in both x& y direction using APIs in Python

I managed to extract base reaction from spec and equavlient static in both directions . I am stuck in getting scale factor already in model and compare it set it to be new scale based (100% of equavlient static ) for both x and y direction . below is the vode I have written so far .Also attached my code . any help? python file also attached

def scaling (model):
""" Retrieves base reactions from EQ,SPEC in the model."""

ret1 = SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput()
ret1 = SapModel.Results.Setup.SetCaseSelectedForOutput("EQX")
ret1 = SapModel.Results.BaseReact()[s][/s]

ret2 = SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput()
ret2 = SapModel.Results.Setup.SetCaseSelectedForOutput("EQY")
ret2 = SapModel.Results.BaseReact()

ret3 = SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput()
ret3 = SapModel.Results.Setup.SetCaseSelectedForOutput("SPECX")
ret3 = SapModel.Results.BaseReact()

ret4 = SapModel.Results.Setup.DeselectAllCasesAndCombosForOutput()
ret4 = SapModel.Results.Setup.SetCaseSelectedForOutput("SPECY")
ret4 = SapModel.Results.BaseReact()

get_scale_factor = SapModel.CaseResponseSpectrum.GetLoads("SPECX")
scale_factor = get_scale_factor[3]

FXeq = ret1[4]
FYeq = ret2[5]
FX_spec = ret3[4]
FY_spec = ret4[5]


RE: Scaling Response spectrum with equavlient static with ETAPS API

Hi Moam93,

Apologies for not getting back sooner, I have been fairly busy this last week.

I think the CaseResponseSpectrum functions are hidden under


I have noticed this sometimes that the python functions don't exactly match the way they are referenced in the chm file.

Hope it helps.

Thanks ! that was the issue .

thanks for helping
