The use of post-tensioning prestressed concrete members is becoming increasingly popular in the United States. Problems have arisen in the design of the anchorage zones of these members, however, as the post-tensioning force has caused cracking in several instances. The anchorage zone itself is a complicated stress region influenced by many different factors. While there have been numerous analytical studies of the stresses present in the anchorage zone, a general lack of insight into the nature of stresses present and the influence of various parameters on their distribution persists. The exploratory investigation reported herein was undertaken to more closely examine the stresses found in the anchorage zone, utilizing the analysis method of photoelasticity. The investigation was to design an appropriate photoelastic model, develop appropriate testing procedures, and then conduct a series of tests varying anchorage zone parameters to determine their influence on the stresses created in the anchorage zone.

Despite the widespread use of cast-in-place and post-installed anchors in construction, the overall level of understanding in the engineering community regarding their behaviour remains quite limited. Furthermore, since the publication of the original CEB design guide, “Design of Fastenings in Concrete”, ongoing research and additional application experience has led to an improved understanding and deepened knowledge in various areas of fastening technology. fib Bulletin 58 therefore represents a substantial revision of the original 1997 guide. It addresses a variety of loading types and failure modes and takes into account the current state of the art for anchorages in new construction as well as for their use in the repair and strengthening of existing concrete structures. fib Bulletin 58 provides a method for the design of the anchorage and additional rules for the design of the concrete member to which the load is transferred. The specified provisions are based on the currently available research.
