I'm reading through ASCE 55-10, Tensilie Membrane structures, since I 'm reviewing a design for a simple arch style tension membrane building. I'm trying to figure out the intent of Life-Cycle Factor, Secton 4.4.2. As I read through the section, I get the impression this life cycle factor applies to the membrane and cables - and not to the supporting steel arch structure??? Can anyone more familiar with this code verify whether this is the case?
There is also another provision, 4.3.5.2, that states a design should consider the effects of of a membrane or cable going slack. What would be a typical consideration of this? Seems logical to me that an increase in applied wind pressure to the structure should be considered as a slack membrane will catch more wind than a tensioned membrane. But how would such a increase be quantified?
Thanks!
