Splice connection is used for both interior and exterior column-to-column connection and can be designed to emulate the characteristics of monolithic cast-in-place concrete. This connection is used when the actual column length is restricted due to production and handling restraints. A spliced column-to-column connection is also used to accommodate future expansions. Column based plates are usually smaller than the column dimension and should be grouted if exposed. The connection is capable of resisting the moment provided the connection is under compression.
Inside Corner, Recessed Angle/plate
This connection is used to correct wall panels at building corners. Its primary function is to keep panels from bowing and/ or to transfer vertical shear force between panels. The connection is durable against corrosion due to the coverage fro grout over the connection. If grouted, a reverse taper or keyway could be placed around the block out to lock the patch into the recess.
The connection is used to attach wall panels together. This connection is used to transfer shear from panel to panel, supporting hanging panels, or to simply provide panel alignment. Special care must be taken to provide adequate concrete cover over the plate anchorages. The connection provides restraint in both the vertical direction and the horizontal direction perpendicular to the panels. It also provides restraint in the plane of the panels.
