STUD SHEAR™ CONNECTOR NOTES
- The above design load and deflections pertain to use of the Stud Shear™ Connector in conventional tie applications. For composite wall utilization, engineering analysis is required to determine allowable loads and deflections.
- The design values reflect both the windward and leeward capacity of the Stud Shear™ Connector tie system, with the governing values listed.
- The tie system recommended design load value was formulated following the procedures of CSA CAN3-A370-M94 “Connectors for Masonry”, ACI/ASCE/TMS/518 and U.B.C. The value has been reduced to account for test result variation, and reflects a factor of safety of 2.25 (i.e., 75% of 3.0), as per Table 3 (A370).
- The allowable mortar pull-out or push-out design load for the V-Tie™ embedded at the centerline of 90 mm (3.5”) brick veneer utilizing Type M, S or N mortar, exceeds or equals the recommended design load listed above.
- The spacing of the Stud Shear™ Connector ties for composite walls will be governed by design, with decreased vertical spacing occurring at the top and bottom of the wall system.
- The above design values relate to the capacity of the FERO tie components. Compatible fasteners capable of resisting the design loads must be selected.
- The above design values are based on tests utilizing a 127 mm (4.5”) cavity (25 mm [1”] air space). No insulation or gypsum sheathing was used. Note that for smaller cavity widths and/or with the addition of insulation and gypsum sheathing providing lateral tie support, increased tie system design loads and reduced tie system deflections may be realized.
- Maximum recommended spacing reflects the maximum allowable by CSA-A370-94, ACI/ASCE/TMS/518 and U.B.C. Design will ultimately govern spacing.
