wood floor joist shear strength

(OP)
What is the best way to estimate the shear strength of a peticular wood truss?  I have been able to backwork span tables to find moment strength, but is there some sort of rule of thumb for max shear?

RE: wood floor joist shear strength

Do you mean wood JOIST or wood TRUSS?  The shear stress in a wood joist is 1.5 times the shear divided by the cross sectional area.  The shear capacity of a wood truss is controlled by the axial capacity of the web member nearest the support.
