OBJECTIVES AND SCOPE

The objective of this committee was to update the previous report, summarizing the State-of-the-Practice for the design of cast-in-place anchor rods, welded anchors, and post-installed anchors as used in petrochemical facilities.

The specific objectives were to:

a. present petrochemical industry anchorage design methods for tension and shear transfer with reinforcement and other embedments;

b. summarize anchorage materials and properties;

c. present current practices for fabrication and installation of anchorage;

d. present recommendations for post-installed anchors; e. make comprehensive recommendations for cast-in-place anchor design which are appropriate for use by the petrochemical industry; f. present recommended fabrication, constructability, and repair practices.

The committee recognized that while several different types of anchorage systems are used in petrochemical facilities, the most common types are cast-in-place anchors, welded anchors, post-installed anchors, and shear lugs. Therefore, for this report, the committee limited its investigation and recommendations to these common types. This self-imposed limit should not be construed as an attempt to limit the importance of other types of anchorage systems. Instead, this limit allowed the committee to f ocus attention on the most commonly used devices.
