1.00 INTRODUCTION 1.01 Purpose The purpose of the testing was to evaluate the structural performance of the twelve submitted Sure-Board® shear wall panels subjected to cyclic racking shear in general accordance with the ICC ES AC154, Acceptance Criteria for Cyclic Racking Shear Tests for Metal-Sheathed Shear Walls with Steel Framing, effective date April 1, 2000. 1.02 Scope of Testing Our general scope of this testing program included the following:

• Test set-up and load fixture fabrication to accommodate the testing. • Perform cyclic shear tests on twelve panels with the given AED value. • Set up data acquisition units to monitor and record the applied loads and corresponding

displacements. • Preparation of this report providing descriptions of the testing and test data.

1.03 Product Description The shear wall specimens measured approximately 4-ft wide by 9-ft high. Each shear wall consisted of one Sure-Board® Series 200 panel fastened to steel stud framing with reportedly thickness equivalent to No. 16 or 18 gage designation. The fasteners used were reportedly ITW screws and nails, or a combination of both. A total number of twelve wall specimens were tested and identified as Test Nos. 2 through 13. Refer to Table 1 and Figure1 below for the construction detail of the wall specimens.

1.04 Test Set-up The test set-up is shown in Figure 2 below. In addition to the two 7/8-inch diameter hold-down bolts (for the hold-down devices, reportedly Simpson Hold-downs shown in Figure 2 and fastened to the outer studs in accordance with manufacturer’s specification), three holes (for 5/8-inch diameter bolts) were drilled at the bottom track to fasten the wall assembly to the test frame steel beam. A hydraulic ram was used to apply cyclic lateral loads through a continuous top loading beam fastened to the top track of each wall. The top loading beam was laterally braced to prevent out-of-plane bending of the wall during the testing.

Figure 2 - Test Set-up 1.05 Instrumentation and Testing Equipment Displacement measurements included two horizontal at the top and the bottom corners of the wall, and two vertical at the two bottom corners of the wall. Refer Figure 2 for clarification. The following is a list of equipments associated with this testing program:

• A Vishay® Scanner (Model 5100) was used for data monitoring and logging. The sampling rate was set as 50 readings per second.

• A Chief® hydraulic cylinder with 18-kip capacity and 8-inch stroke. • A Tovey® load cell (Model SW 20-25k) with 25-kip capacity. • Three Celesco® cable extension transducers (Model PT-1A) with 1-inch measuring range. • Two Celesco® cable extension transducers (Model PT101) with 15-inch measuring range.

The system calibration files for all measuring instruments are included in Appendix C.

1.06 Test Procedure Cyclic loading was in accordance with the procedure noted in AC154. As requested by client, an Approximate Elastic Displacement (AED) value of 0.6 inch was used for all the tests. The target top displacement for each loading cycle is summarized in Table 3 below.

To ensure the loading frequencies are within 0.2 to 1.0 cycle per second, an appropriate sized hydraulic cylinder and pump were selected for the test. In addition, the controlling parameters such as acceleration and velocity were adjusted before the test to meet the requirement. A typical loading history and period are shown in Figure 3 below.

2.00 RESULTS AND FINDINGS A total number of twelve 4 ft by 9 ft shear wall assemblies were tested, and results summarized in Table 4 below. As defined in Section 4.4.1.2 of AC154, the maximum strength of each wall assembly was determined based on the peak force at the second cycle of the last stable set of hysteretic loops (defined in Section 4.4.1.3 of AC154). The load versus displacement hysteretic loops and the graphs of measured displacements for each shear wall assembly are included in Appendix A.
