Building Codes Are Changing - New Anchor Designs Now Required
Most states across the country have now adopted the 2012 International Building Code (IBC) and many jurisdictions within each state are now enforcing the new code. As a result, engineers and designers are increasingly being required to specify anchors designed and tested to meet the new requirements of the code. The 2012 IBC requires that Strength Design methodology be used when designing structural anchorages within buildings and other structures. This affects how and when post-installed concrete anchors are specified and what products will be suitable for use.
When designing concrete anchorages, designers are now being required to consider, among other things, whether conditions exist that may cause the concrete to crack. If it's determined such conditions do exist, anchors designed and tested for use in cracked concrete must be specified. If it's determined there is no risk of concrete cracking, the designer may choose to specify anchors approved for use in uncracked concrete. In either case, strength design methodology is required as part of the 2012 IBC.
Simpson Strong-Tie Anchor Systems offers both adhesive and mechanical anchors that meet the 2012 IBC requirements and are ICC-ES code listed for use in cracked-concrete environments.

Common conditions that cause cracking of concrete
- Concrete in tension – such as in the underside of a slab
- Concrete elements located in areas prone to seismic activity
- Other factors that contribute to cracking include:
- External short term loads (such as high winds)
- Temperature variations
- Shrinkage during curing
