Abstract:
Ninety-day load-relaxation tests at room temperature were conducted on a full range of sizes of heavy duty sleeve and lead caulking expansion anchors. The test results showed that the sleeve and lead caulking anchors on the average are able to retain only 60 and 40 percent of their initial tension load, respectively.
