SIDE MOUNTING RAP-TIE NOTES
| (i) |
The design values reflect both the windward and leeward capacity of the Side Mounting Rap-Tie system, with the governing values listed.
|
| (ii) |
The tie system recommended design load value was formulated using working stress design 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 reflect a factor of safety of 2.25 (i.e., 75% of 3.0), as per Table 3 (A370).
|
| (iii) |
The allowable mortar pull-out or push-out design load for the V-Tieª 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.
|
| (iv) |
The above design values relate to the capacity of the FERO tie components. Compatible fasteners capable of resisting the design load must be selected.
|
| (v) |
The above design values are based on test results utilizing a 76 mm (3?) cavity (25 mm [1?] air apace). No insulation or drywall was used. Note that for smaller cavity widths and/or with the addition of insulation sheathing providing lateral tie support, increased tie system design loads and reduced tie system deflections may be realized.
|
| (vi) |
Maximum recommended spacing reflects the maximum allowable by CSA-A370-94, ACI/ASCE/TMS/518 and U.B.C. For stud construction, every vertical stud should contain ties. Design will ultimately govern spacing. |
