Can the HD-6 anchor be used in seismic design category D at 6″ embedment?
Answer · 2 sources
Yes, with conditions. At 6″ embedment in 4,000 psi normal-weight concrete, use the reduced seismic tension value from Table 4 and apply the 0.75 factor per the design flowchart. Special inspection is required.
