SLOTTED
STUD TIE (TYPE I) NOTES
| (i) |
The design values reflect both the windward and leeward
capacity of the Slotted Stud Tie (Type I) 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 reflects 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-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.
|
| (iv) |
The above design values relate to the capacity of the
FERO tie components. Compatible fasteners capable of
resisting the design loads must be selected.
|
| (v) |
The above design values are based on test results utilizing
a 127 mm (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 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. |
