BoxRedford Station, Detroit “. On the other hand, depending on the application in 349-855, the predictions of ACI are sometimes unconservative and sometimes conservative. A user-friendly, highly transparent model for the design of post-installed steel anchors or cast-in-place headed studs or bolts, termed the concrete capacity design CCD approach, is presented.
