SSTB® ANCHOR BOLTS
|
Extensive SSTB testing has been done to determine the design load
capacity at a common application, the garage stem wall. Design loads are based on the
lowest ultimate, from a series of five tests, with a three-times safety factor.
SPECIAL FEATURES:
- Rolled threads for higher tensile capacity.
- Offset angle reduces side-bursting, provides more concrete cover.
- Stamped bolt head for identification after pour.
- Stamped embedment line aids installation.
- Configuration results in minimum rebar interference.
INSTALLATION:
- SSTB is suitable for monolithic and two-pour installations.
- Nuts and washers are not supplied with the SSTB; install standard
nuts, couplers and/or washers as required.
REINFORCED CONCRETE FOUNDATION
- Install SSTB before the concrete pour using an MKP (see page 25 for MKP). Install the SSTB diagonally at approximately
45° from the wall. Install one #4 rebar 3" to 5" from the top of the
foundation. The SSTB does not need to be tied to the rebar.
- Minimum concrete compression strength is 2500 psi. Unless noted
otherwise, no special inspection is required for foundation concrete when the structural
design is based on concrete no greater than 2500 psi (1997 Uniform Building Code, section
1701.5.1).
- Use 90% of the table load for 2000 psi concrete.
REINFORCED CONCRETE BLOCK
Before concrete pour, install diagonally at approx. 45° in the
cell.
Horizontal #4 rebar (minimum 56" long) -- approx. one rebar
12" from the top and two rebars approx. 28" from the top.Vertical #4 rebar
(minimum 24" long) -- install with maximum 24" o.c. spacing.
Grout all cells with minimum 2000 psi concrete. Vibrate the grout
per the 1997 Uniform Building Code, section 2104.6.2.
OPTIONS: Available in hot-dip galvanized; consult
Simpson.
CODES: ICBO 4935, City of L.A. RR 25152 for
concrete foundation only.

- Loads may not be increased for short-term loading. Loads apply to
earthquake and wind loading per 1997 UBC Sections 1909 and 1923.
- Minimum anchor center-to-center spacing is 2le for anchors acting in
tension at the same time for full load.
- The SSTB was tested in a stem wall with a minimum amount of concrete
cover.
- Maximum allowable load is 8150 lbs. for earthquake and 7190 lbs. for
wind for SSTB28, 34 and 36 used 5" from the end of a concrete foundation. Use full
table load when installed 24" from the end or installed in a corner condition (see
illustration).
- Connection is limited by lowest of bolt or holdown capacity.
