After a significant seismic event, what should be done regarding adhesive anchors?

Following a significant seismic event, it is critical to inspect adhesive anchors thoroughly for any potential damage. This is due to the fact that seismic activities can induce forces and stresses that may compromise the integrity of the anchor systems. These forces can lead to various types of damage, such as cracking in the substrate or deterioration of the adhesive bond, which might not be immediately visible without a detailed inspection.

Thorough inspection helps ensure that the adhesive anchors remain capable of performing their intended functions in the structure. It is also essential for assessing whether repairs or replacements are necessary to maintain safety and structural reliability. Simply leaving them as they are without inspection ignores the risk of hidden damage that could lead to failure under load. Additionally, replacing anchors without inspection can be unnecessarily costly and may not address the specific issues present.

Ultimately, a comprehensive post-seismic inspection is crucial for confirming the performance and safety of adhesive anchors in order to protect the structure and its occupants.
