ETABs API - Steel Beam Design Shear Reactions 1

[sticksandtriangles]

Is there any way to access beam end shear reactions through the API for steel beam design like that of composite beam designs?

There is a nice method in composite beam design (DesignCompositeBeam.GetSummaryResults) that returns ReacLeft and ReacRt that does the trick for composite beams.

Unfortunately for steel beams, it does not look like there is a similar function that returns beam end shear reactions. I can access shear ratios and combos, but not the end beam shear force.

One work around is the following code, but it does not capture live load reduction like directly accessing the design results would.

SapModel.Results.Setup.DeselectAllCasesandCombosForOutput
SapModel.Results.Setup.SetComboSelectedForOutput("Envelope")

Name = "31"
eItemTypeElm = 0
NumberResults = 0
Obj = []
ObjSta = [0,1]
Elm = []
ElmSta = []
LoadCase = []
StepType = []
StepNum = []
P = []
V2 = []
V3 = []
T = []
M2 = []
M3 = []

y = SapModel.Results.FrameForce(Name, eItemTypeElm,NumberResults,Obj,ObjSta,Elm,ElmSta,LoadCase,StepType, StepNum, P, V2, V3, T, M2, M3)

def getMaxRxns(results):
    stat_repeat = int(results[0]/2)
    left = max(abs(results[9][0]),abs(results[9][stat_repeat-1]))
    right = max(abs(results[9][-1]),abs(results[9][-stat_repeat]))
    return [left, right]

end_rxns = getMaxRxns(y)
print(end_rxns)

I made an envelope of load combinations I was interested in and pick the results from there.

Nice one, transferring ETABS beam end reactions to Revit shared parameters?

Currently trying to automate simple shear connection checks based on tables of standard capacities that we have.

Seems like RAM has the checking of gravity beam shear tab connections down well and ETABs is a little lacking.

ETABS lacking practicality... Well I never!
