Anchorage Adhesives

Strong-Rod Systems

Typically, rod runs will terminate at the foundation, using the dead load of the concrete to ultimately resist the uplift demands. The building code does, however, allow the designer or Engineer of Record to use a percentage of the dead load expected to exist during a wind event (with the percentage based on load combinations for either Strength or Allowable Stress Design). Consequently, if the uplift loads are low enough and dead loads are high enough, it is possible to terminate the rod runs underneath upper wood floors.

SET-3G™ High-Strength Epoxy Adhesive

SET-3G is the latest innovation in epoxy anchoring adhesives from Simpson Strong-Tie. Formulated to provide superior performance in cracked and uncracked concrete at elevated temperatures, SET-3G installs and performs in a variety of environmental conditions and temperature extremes. The exceptional bond strength of SET-3G results in high design strengths at shallow embedment depths. Code listed per ICC-ES-ESR-4057 in accordance with ICC-ES AC308, ACI 355.4 and IBC 2018 requirements for cracked and uncracked concrete in static and seismic conditions, SET 3G anchoring adhesive can be installed when concrete substrate temperature is as high as 100°F (38°C).

AT-XP® Fast-Curing Anchoring Adhesives

AT-XP anchoring adhesive from Simpson Strong-Tie has been formulated for high-strength anchorage of threaded rod and rebar into concrete under a wide range of conditions, such as cold weather installations. Code listed per IAPMO UES ER-263 in accordance with ICC-ES AC308, ACI 355.4 and IBC 2018 requirements for cracked and uncracked concrete in static or seismic conditions, AT-XP anchoring adhesive has demonstrated superior performance in reduced-temperature testing (can be installed in concrete substrate temperatures as low as (14°F (–10°C)).

Titen HD® Rod Coupler Screw Anchor for Concrete Foundations

The Titen HD rod coupler screw anchor is designed to be used in conjunction with a single or multi-story continuous rod tie-down system. This anchor provides a fast and simple way to attach threaded rod to a concrete stem wall or thickened slab footing. Unlike adhesive anchors, the installation requires no special tool, cure time or secondary setting process; just drill a hole and drive the anchor.

Allowable (ASD) Tension Loads for Post-Installed Anchors into Uncracked Concrete for Wind Loads

Allowable (ASD) Tension Loads for Post-Installed Anchors into Uncracked Concrete for Wind Loads
  1. Allowable tension loads are based on the Strength Design provisions of ACI 318-14 and have been converted to Allowable Stress Design (ASD) levels by applying a 0.6 factor for Wind loads.
  2. Tabluated values are applicable to the conditions listed below. Refer to the Simpson Strong-Tie Anchor Selector™ Design software for other conditions.
    1. Minimum concrete compressive strength = 2,500 psi
    2. Uncracked concrete
    3. Dry concrete
    4. Periodic special inspection
    5. Maximum short-term temperature = 150°F
    6. Maximum long-term temperature = 110°F
  3. Tabulated values apply to design tension loads consisting of 100% wind loads.
