SB Anchor Bolt

The geometry of the SB bolt is the latest development in high capacity anchors. The smooth transition angle of the bolt positions the head of the anchor into an optimum position in the concrete stem wall without creating excessive horizontal forces. The SB7/8x24 is designed to maximize performance with minimum embedment while the SB1x30 is intended to cover holdown devices that exceed the capacity of SSTB anchors.

Special Features:

Identification on the bolt head showing embedment angle and model
Stamped embedment line
Rolled thread for higher tensile capacity
Tested in different compressive strength concretes for versatility in specification

Material: ASTM A36

Finish: None. May be ordered HDG; Contact Simpson Strong-Tie.

Installation:

SB is only for concrete applications poured monolithically.
Install 1 - #4 rebar in the area 3" to 5" (may be foundation rebar not post-tension cable) from the top of the foundation.
Top nuts and washers for holdown attachment are not supplied with the SB; install standard nuts, couplers and/or washers as required.

Selections assume installations into a continuous stem wall or in a corner. Minimum f'_c = 2500 psi.
No cold joint within the embedment depth.
The Design Engineer may specify an alternate anchorage system provided the diameter is the same.
Where noted, the allowable load for this application is 13675 lbs which is less than the published loads for these holdowns. For concrete strengths 3000 psi or greater, the maximum allowable load for the holdown can be achieved.
Where noted SB7/8x24 may be used on 3" (post) wood member thickness when using f'_c = 3000 psi for the foundation concrete.
Where noted SB1x30 may be used for 5 1/2" (post) wood member thickness when 3000 psi foundation concrete is used. 3 1/2" and 4 1/2" (post) wood member thicknesses may be used when using 2500 psi foundation concrete. See (post) wood member thickness info.
When SB is used with the HD holdown and a sill plate greater in thickness than 1 1/2", then provisions must be taken to extend the SB.

Loads may not be increased for short-term loading. Loads apply to earthquake and wind loading.
Minimum anchor center-to-center spacing is 3 l_e for anchors acting in tension at the same time for full load.
Allowable loads are based on ultimate test load divided by a factor of 3.0. Contact Simpson Strong-Tie for testing and design information.
For two pour installations (see drawing) with a SB1x30, use the table loads for the SB7/8x24.
Testing to new ICC-ES acceptance criteria to be completed in 2009. Refer to this website for latest loads and information.
