Horizontal lifeline

Horizontal lifeline

Horizontal lifeline

Hey everyone, I'm trying to design an horizontal lifeline with Robot structural analysis and I have a lot shadow zones of understanding:
1) When falling,the energy absorber stops the fall and the dynamic load applied to my cable is equivalent to that static maximal arrest force? (MAF=Mg(1+(1+Kf/Mg)^(1/2))
2) My lifeline is expected for multi tie-off use (7 users) Is there any simultaneity falls studies on the matter (something like the diminishing return on economics) or should I design for 7*MAF (I wish I won't have to do so)
3)How would you model the wind effect on a structure like this? (almost linear and no surfaces; a prestressed cable connected to two columns)
4) I guess that the effectof wind on the 7 people is something to take account of, even more than on the stucture itslef my intuition says, should take some equivalent surface for each person and calculate the wind load on it?
5) Someone has any ideas of how to simulate the resonance that would arrive due to wind or parasismic effects?
Thank you advanced
