This drawing outlines the standard detailing requirements and bend dimensions for seismic stirrups and tie hooks featuring a one hundred thirty-five degree hook. A reference table provides specific bend diameter D, hook extension length A or G, and approximate total hook length H for bar sizes number three through number six. The diagram indicates a bend angle of one hundred thirty-five degrees with a minimum extension of six times the bar diameter or three inches. Additional annotations specify detailing dimensions and extension lengths, including twelve times the bar diameter for number six bars.
