EVALUATION OF CAST-IN-PLACE CONCRETE INSERTS USED IN NEW PORTLAND CEMENT CONCRETE STRUCTURES. FINAL REPORT

The results of direct tension, direct shear, and combined tension and shear tests on two common types of cast-in-place concrete inserts, ferrule loop and ductile cast-iron, from four major manufacturers are presented. Tests were performed at the minimum edge distance recommended by manufacturers and also at half of that distance using both 5000 psi concrete and a low strength, 3500 psi concrete. A detailed test method, California Test 682, was developed and written for determining ultimate tensile strength of cast-in-place inserts, and a revised California Department of Transportation Standard Specification for cast-in-place inserts was written. A table for recommended design loads for tension and shear was also prepared. Plots of ultimate load vs edge distance were prepared, and also an interaction curve for combined tension and shear loading was developed.
