| RAP-TIE STRUCTURAL COMPOSITE ACTION
In most applications, the Rap-Tie is designed to simply transfer the lateral load from the exterior masonry wythe (the veneer) axially to the structural backing, and a single fastener will usually prove adequate. However, by using two fasteners to attach the L-Plate to the structural backing, shear forces as well as axial forces can be resisted by the Rap-Tie to provide composite action between the masonry veneer and the structural backing. The entire wall thickness, including both veneer and structural backing, becomes effective in resisting lateral loads, offering reduced lateral deflections and increased lateral resistance (see FERO Stud Shear™ Connector or Block Shear™ Connector literature). A Rap-Tie can be used for retro-fitting masonry veneer systems where reducing lateral deflection of the steel stud structural backing is a required intervention. (Use the FERO Shear Truss program to evaluate forces in the assembly). |
