I have a laminated glass panel wall that is spanning vertically 6 ft and fixed at the base. Typically I have seen modulus of rupture values of 24000 psi for glass panels (tempered/laminated).Also typically a factor of safety of 4 is used to obtain the allowable bending stress = 6000 psi.Does any one know if a lower F.S. can be used or if for laminated glass a higher Mod of rupture can be used? In IBC 2003 ch. 24 a F.S. of 4 is recommended for Guard rail etc. but this is not a guard rail.it separates 2 areas on the same level.
