SI,° \ ERRA" WALL SYSTEM CONNECTION CALCULATIONS Connection is the amount of resistance of the reinforcing has to a pullout failure from the facing units based on the Tmax applied and the normal load on the units. In an AASHTO LRFD design, creep on the connection may be applied for frictional and mechanical connections. In NCMA or AASHTO 2002, a frictional failure is based on the peak connection capacity divided by a factor of safety. For a rupture connection the capacity is the peak load divided by a creep reduction factor and a factor of safety. Frictional Connection Peak Connection = N(ppf)tan(slope) + intercept Rupture Connection Connection Capacity= [N(ppf)tan(slope) + intercept]/RFcr RFcr can be a value obtained from long-term testing or by default could be the creep reduction factor of the geogrid reinforcing.
