Design of Bearing Plates for Anchors in Geo-Application
Andrew Baxter, Sixto Fernandez, Dr. Jesús E. Gómez

This paper focuses on the design of steel bearing plates to transfer load from tiebacks and tiedowns to a concrete mass. It lists and describes the various available procedures for design of bearing plates as well as explains the design procedure recommended by the authors, which incorporates the Post Tensioning Institute (PTI) recommendations. The paper includes a step-by-step design example following the recommended procedure that captures the most important aspects of plate design. The dimensions of the plate calculated from this example are compared to the design dimensions obtained from various other procedures, including those by American Association of State Highway and Transportation Officials (AASHTO) and VSL International, Ltd. (VSL). The paper also includes the results of numerical modeling of the plate that will help the reader understand important aspects of plate-concrete interaction. The authors envision that this paper will serve to create an understanding in the geoindustry of suitable design methods and help improve procurement of bearing plates for tiebacks and tiedowns.
