APPENDIX F
SEISMIC QUALIFICATION PROCEDURE AND ACCEPTANCE CRITERIA FOR OTHER SHEAR
PANEL CONFIGURATIONS
F1. SCOPE. This appendix presents the test procedure, acceptance criteria and documentation
requirements needed to demonstrate the acceptability of cold-formed steel shear panel configurations
different than the specific system defined in Chapter 3. Acceptable panels are limited to cold-formed
steel shear panels with diagonal straps or full panel sheets as the lateral load resisting elements. The
columns shall be constructed with cold-formed or hot-rolled structural steel. This is for the
qualification of a prototype of the specific panel that will be used in construction. Qualification
requires the testing of three specimens. All panel tests shall represent full panel system tests of all
the panel components including connections, and anchors.
F2. COUPON TESTS OF ALL TEST PANEL MATERIALS. Coupon tests shall be performed on all
materials that may contribute to the structural performance of the test panels. At least three coupons
shall be tested from each lot of each type of material. Coupons shall be prepared and tested
following the provisions of ASTM A 370. Materials that contribute to the ductility of the shear panels
shall have a total elongation of at least 10% for a two-inch long gage length. All coupon test results
shall be plotted in a test report, in terms of stress versus strain. All coupon test results shall also be
summarized in a table in the format shown in Table F-1. The data in this table shall be the average
value of the three or more coupons of the particular component.

F3. COUPON TEST OF ALL FIELD PANEL MATERIALS. Coupon tests shall be performed on all
materials that contribute to the structural performance of the field panels. The field panels shall be
identical to the prototype-tested panels. At least three coupons of each material shall be tested.
Coupons shall be prepared and tested following the provisions of ASTM A 370. Materials that
contribute to the ductility of the shear panels shall have a total elongation of at least 10% for a two-
inch long gage length. All coupon test results shall be plotted in a test report, in terms of stress
versus strain. All coupon test results shall also be summarized in a table in the format shown in
Table F-1. The data in this table shall be the average value of the three or more coupons of the
particular component. The field diagonal straps or full panel sheets shall have a coupon yield stress
(0.2% offset) not greater than 5% above or not less than 10% below the test panel coupon yield
stress (0.2% offset). The field material coupons for all other structural elements shall have coupon
yield stress (0.2% offset) not less than the test panel coupon yield stress (0.2% offset).
F4. TEST CONFIGURATION. Full-scale test panels shall be tested with both monotonic (pushover
in one direction) and cyclic loading. The panels shall be anchored to a base beam and top beam in a
manner representative of the field installation. The base beam shall resist any slippage, out-of-plane
movement or rotation in any direction. Vertical load shall be applied to the shear panel through the
top beam, at a level representative of potential gravity loads in the field. The amount of vertical load
applied should consider the worst case condition for the most vulnerable panel components. For
example, the minimal vertical load may provide the most severe loading for the anchors, while the
maximum vertical would provide the worst case loading for column buckling. This vertical load shall
