Additional Anchor Designs

In addition to anchorage solutions provided by the SB and SSTB anchor bolts, the following table provides design options obtained through calculations from either the 1997 UBC Section 1923.2 or the 2006 IBC per ACI 318-05 App. D. These solutions may be used with Simpson Strong-Tie holdowns.

Anchor with Nut/Washer/Nut (shown) or Hex-Head Bolt
Design loads are calculated using a full shear cone.
Coverage on each side of the bolt shall be a minimum of F or reductions must be taken.

Anchor embedment length is based on a single-pour concrete foundation within the footing dimensions d_e and F. Double pour foundation systems, masonry walls and masonry footings must be evaluated by the Designer.
Anchor bolt must be ASTM A307 orA36 steel.
Anchor head requires two hex nuts with a 2 1/4"x2 1/4"x3/8" plate. Use of a Simpson Strong-Tie Bearing Plate BP1 may be used as a substitute for 1" diameter bolts.
Published loads are for use with Allowable Stress Design. IBC Seismic values denote SDC C through F. IBC Wind values include SDC A and B.
UBC values assume no special inspection and no supplemental reinforcement. For ACI 318-05, cracked concrete is assumed and for high seismic areas ductility requirements per D.3.3.4 are considered.
