Tests to measure load relaxation were performed on embedded A307 bolts, grouted A307 bolts, wedge bolts, and undercut anchors. The data on undercut anchors included tests on bolts of five sizes, and the tests were generally of longer duration than
Julius G. Potyondy
A detailed research program in presented on cast-in-place anchorages in concrete. Single and multidowel units were tested under transverse loads with variable moment arms. The strain distribution along the embedded anchors was measured to determine the re

Results are reported of tests to failure in either shear or tension of 27 cast-in-place anchor bolts. Variables included bolt size, embedment depth, thickness, and diameter of washers inserted beneath bolt heads, size of concrete specimen, and concrete st

Twenty-three 1-3/4 in. diameter and 1 in. diameter anchor bolts were tested in an investigation of the effects of clear cover, bolt diameter, embedment length, and bearing area of the anchorage device on the strength and behavior of anchor bolt installations. Failure modes are identified, and the load carrying mechanism of an anchor bolt is described. The data were combined with the results from earlier studies and analyzed using a multiple stepwise regression procedure. A simple equation for the ultimate load of a single anchor bolt loaded in tension is presented.
The behavior of metallic expansion anchors under monotonic loading is described on the basis of a large number of available test results. Expansion anchors loaded in tension will often fail in a rather brittle manner by pulling out a concrete cone. The co

Forces are frequently transferred across the joints between precast reinforced concrete members through anchorages composed of embedded steel plates and concrete anchors. The purpose of this paper is to present the results of an investigation into problem
Edwin G. Burdett, Teresa C. Perry, and Raymond R. Funk
Tests were performed on undercut anchors to determine their capacity under various combinations of static and dynamic loading. The anchors were set in holes that had been undercut or belled out by a second drilling operation. In the process of setting an
L. D. Noble, M. J. Meyer, and G. L. Koci
Present nuclear power plant design methods require that Seismic Category I pipe supports consider plate flexibility in determining the loading of expansion anchor bolts. Base plate flexibility has been determined to cause significant unequal loading when
Ronald D. Guthrie, Raymound R. Funk, andEdwin G. Burdette
Steel embedments are utilized to transmit load from equipment, piping systems, cable trays, and similar apparatuses into reinforced concrete structures. The types of embedments or anchors may be postinstalled--such as expansion shell, wedge, undercut, and
Frank G. Schwarz
The paper discusses the results of a test program comprised of 60 tensile tests of wedge-type expansion anchors installed in uncracked concrete. Typical anchor performance is analyzed during the installation, intermediate loading, and ultimate failure sta
