Testing, Design, and Specification

A variety of factors influence an engineer’s decision to use  cast-in anchors or post-installed anchors including working principles, installation, and the impact on project timeline and budget. Above all, a licensed engineer shall hold paramount their code of ethics and the safety, health, and welfare of the public. At a time in which budget and scope have tightened for professional engineering work, it is difficult to allocate resources to sift through technical data and footnotes for a comprehensive comparison of post-installed anchoring systems. This article establishes an understanding of the chemical and physical factors that affect the performance of post-installed adhesive anchor systems. It also explains how product testing is incorporated into design calculations and provides suggestions for designing and specifying adhesive anchor systems. …
