Does anyone know of any standards for using live trees in the design of a structure which carries people? It is for a zipline that would be used to carry one person at a time. I would recommend that the tree be load tested to 1.5-2 times the design load, but I don't think that is enough. There is just not a good way to be able to model a trees root system. Any suggestions would be appreciated.
