allowable wood arch deflection
 

allowable wood arch deflection
anyone know any good guidelines for vertical and lateral deflections of the main menber of a semi-circular wood arch section? unbalanced snow load is killing me here!

checked the 2005 nds, probably me but can't find anything.
1994 aitc timber manual, 4th edition says "specific deflection limitations forarches have not been generally established becaseu this is a function of the intended use."
sorry can't help,
good luck and let us know what you find/decide.
