Abstract: The basic philosophy underlying the design of steel embedments may be summarized as follows: (1) If an attachment can be located such that a group of cast-in-place anchors can be used to support the baseplate, or if the attachment can be affixed to an embedded plate, then the preferred embedment system is possible for this attachment. (2) There may be instances where the specific location of an attachment is not known in advance, but a reasonable probability exists that attachments will need to be located in a particular area. In such instances, a logical approach is to install embedded strip plates to which attachments may be welded or to install a grid of threaded inserts to which baseplates may be bolted. (3) In many instances, there is no cast-in-place anchorage system present at the place where an attachment must be located. In such a case, the design logically chooses either a type of expansion anchor or a grouted-in anchor.
