Scissor-Like element

Hi

My purpose is to analyse a scissor like element in karamba, wich Ive modeled in grasshopper and I fabricated the prototype in 1-1 scale  . For analyzing it I have some questions.

1- how to define joins in karamba

2- how to analyse each scissor

3- how to predict the behavior of the membrane 

4- how to analyse wind in karamba for my structure

please explain the process. Thank You
