Horizontal Shear Studs

    Hello all,
    I'm looking for input in installing an HSS steel beam with horizontal welded shear studs at one end, while it's either welded or bolted on the other end. It can be seen in the case of connecting a precast wall to a concrete column. Beam is bolted to column but grouted into the face of the wall after studs embedded.

    Dear Sayed,

    It would help if you could present your question by a sketch; a sketch speaks a thousand words; while text can be visualized in different ways by different people.

    I'm looking forward to seeing your sketch.

    Thank you Stephanie for sharing the sketch. One of the group's member asked for a  rough sketch while, I was at a coffee shop waiting for my order at moment, all I found was a napkin... it is just a draft but still can describe one thousand words...

    Dear Stephanie Lynn Slocum,  

    Detail description of the sketch drawing is necessary for the understanding, otherwise it will look like an illustration or typical design case study.
    Thanks.

    I would second what Olusegun said.

    Why not have the precaster embed the connection plate instead of trying to grout the studs into a pocket?  Then the field installation portion becomes a field weld instead of grouting; which I would think would be easier and more reliable.

    I agree with Eric Christensen regarding casting the embed plates into the precast piece when the piece cast, unless of course, the connection is a retrofit to a piece that is already cast. If it is a retrofit, I would utilize a post-installed anchor system that meets the ACI cracked concrete requirements and the seismic requirements for the area; I would not rely on a grouted shear stud type of connection into the vertical face of a precast member. Just my opinion after 48 years of practice...

    I agree 100%, Larry Swayze.  In a retrofit situation PI anchors are the best bet.

    I also had to laugh; "Just my opinion after 48 years of practice..."  *drops mic*

    Dear group members,

    I appreciate all your comments and suggestions. I would second considering PI anchorage for retrofitting structural members. Steel plate PI embedment into the face of precast wall is often use for welding none-structural members to it. Grouting into the precast to install beam would be just fine design, in the case of connecting  a none-structural steel beam to the face of the wall.
