2nd Edition: Base Plate and Anchor Rod Design (Guide 1), covers another type of grout pocket that is not discussed in this article: shear lugs embedded in a grout pocket in a concrete pedestal. Unfortunately, Guide 1 does not provide specific guidance on grout pocket design and sizing, other than recommending that the grout pockets be of
column-to-foundation connection is usually done: i) by using steel base plates; ii) by adopting column pockets, grouted in-situ; iii) by means of grouted sleeves. Both from the point of view of prefabrication and of seismic response, steel base plates appear to
• bolted base plates embedded in the foundation • foundation pockets in which the columns are placed and grouted • grouted sleeves • mechanical splices This paper investigates the behavior and performance of grouted corrugated steel sleeve connections under cyclic loading. While the behavior of precast concrete socket base
grout joint. Most columns will have a base plate for attach-ment to the foundation or another precast concrete element through anchor bolts, splice sleeves, or both. This base plate is normally constructed of ¾ in. thick (19 mm thick) steel and covers the entire surface; however, some columns may only use this plate at the corners for anchor ...

Abstract. Connections between precast concrete elements must be able to withstand significant stresses and deformations in earthquakes. The grouted splice sleeve connector is being considered for use in accelerated bridge construction.
