structural glass design
i am looking for some advise on how to check the capacity of some glass walls. this is laminated insulating glass. the panels consist of 3 panes the outer layers are 1/2" and an inner 1/4" layer with 3/4" spaces between the panes. the panels are 7' wide and 15' tall only supported at the bottom and top edges.
i have looked at astm e1300 design charts for 2 edges of support but the lengths they stop at are less than the ones i am looking at. can i...and if i can how do i extrapolate these tables to meet my criteria. also any help or explanation on how the 3 lites work together to resist wind forces would be helpful ( do i just add the 3 lite thickness together to check the load resistance)?
no glass experts out there?
