Dear AlohaBob:
Subj: Helical Stair
I would rephrase my question this way:
Is the output as regards torsional magnitude as given by computer program good enough for further calculation for stress analysis through hand calculation by AISC/ACI methods?
With best regards, I end here.
Helical stair is also an example of curved beam. This can be solved by inputting the co-ordinartes and load magnitude in computer program. I use MULTIFRAME 3D program.
My question is: Is the result from the computer program acceptable as regards its output on tosional stresses
Can any of our...
