Typical design stress vs. Allowable bending stress
Typical design stress vs. Allowable bending stress
(OP)
I am designing a 1/2" thick x 3'-0" wide soda-lime-silica float glass to span over 4'-0" OC (3 span, typical). The manufacturer has provided me with typical design stress for 0.8% probability of breakage, typical mean modulus of rupture and other bunch of properties. However, there is no allowable bending stress provided. What is the relation of typical design stress vs. allowable bending stress? How can I check that 1/2" thick glass as mentioned above can span 4'-0" OC for 40 PSF total load (DL+LL)?

Look for the program MEPLA, a FEM program for glass, for more conservative values.
