I. OBJECTIVE The objective of the test program was to determine the lateral load resisting capacity of shear walls framed with light gauge cold-formed steel and sheathed with Intermat, Inc. Sure-Board Series 200 structural panels. The Sure-Board structural panels were fastened to the framing members with a combination of self-drilling screws and AeroSmith pneumatic nails. The results of the test program will be submitted to ICC-ES for evaluation. II. TEST STANDARDS The test program was performed in compliance with ICBO-ES AC 130-2002 (2004) - Acceptance Criteria for Prefabricated Wood Shear Panels. The panel testing was performed in accordance with the Standard Method of Cyclic (Reversed) Load Test for Shear Resistance of Framed Walls for Buildings – 20 January 1997, by the Structural Engineers Association of Southern California (SEAOSC). The SEAOSC criteria shall be referred to herein as the Standard Method. III. SCOPE OF TESTING The scope of the test program is presented in Table 1. Twelve single panel tests were performed in the foundation on grade configuration (ICBO-ES AC130 Section 5.2.2.1).

IV. TEST PROGRAM SPONS0R The test program was performed under a contract with Intermat, Inc. who sponsored the test program. V. LABORATORY OF RECORD Spec Testing, Inc. (dba Specialized Testing - IAS TL228) was the laboratory of record. All tests were performed at Specialized Testing’s laboratory located at 10600 Pioneer Blvd. – Suite G, Santa Fe Springs, CA. A single test was performed in January of 2004 and two tests were performed in August of 2005. VI. TEST SPECIMEN DESCRIPTION SURE-BOARD STRUCTURAL PANELS (SHEATHING) Two Sure-Board Series 200 Structural Panels were tested in the program as follows: • 4ft. x 9ft. sheet of Sure-Board 1/4-in. thick Magnesium Board. • 4ft. x 9ft. sheet of Sure-Board 5/8-in. thick Densglass Gold exterior sheathing manufactured by Georgia Pacific. LIGHT GAUGE COLD-FORMED STEEL FRAMING MEMBERS The framing members were Cemco (ICBO-ER3403P) 16-gauge and 18-gauge S studs and C tracks members. The walls were sheathed on one side with one of the two Sure-Board Structural Panels. The studs were spaced at 16” o.c..; the end posts were back to back studs; the bottom and top tracks were 16-gauge and 18-gauge members. BASE ANCHORAGE The shear walls were anchored at the base with Simpson SHD/10 or SHD/15 holdown connectors. Bottom track “sill” anchors were positioned in each stud – three total for each test wall. The sill anchors were 5/8-in. diameter ASTM A193 Grade B7 threaded rod anchors located in each stud bay. SURE-BOARD FASTENERS The Sure-Board Series 200 Structural Panels were attached to the framing members with a combination of Grabber self-drilling screws (ICC-ES ER5280) and AeroSmith pneumatic nails (ICC-ES ER5667). The Grabber self-drilled screws were No. 8 x 1-3/4-in. long. AeroSmith 1-1/4” long x 0.100-in. diameter - knurled shank - pneumatic nails with a 5/16-in. diameter head were used in the Sure-Board Series 200 Densglass Gold shear walls. AeroSmith 1-3/8” long x 0.100-in. diameter - knurled shank - pneumatic nails with a 1/4-in. diameter head were used in the SureBoard Series 200 Magnesium Board shear walls. Fastener spacing was as follows:

Vertical Perimeter Fasteners • Self-drilling screws at 12-in. on-center in the perimeter post members. • Five AeroSmith pneumatic nails were installed between the self-drilling screws at roughly 2in. on-center. The pneumatic nails were staggered above the holdown connectors and installed in a single row from the top of the holdown connector to the base of the shear wall. Vertical Field Fasteners • Self-drilling screws at 12-in. on-center. • AeroSmith pneumatic nails at 12-in. on-center (installed between self-drilling screws). Horizontal Perimeter Fasteners • Self-drilling screws at 2-in. on-center (horizontally) in the top and bottom plate members. Figure 1 presents a close-up photograph of the fastener installation pattern. VII. SAMPLING The Sure-Board Series 200 Structural Panels were proto-type panels that were delivered assembled to Specialized Testing by Intermat. No independent sampling was performed. VIII. TEST EQUIPMENT The test equipment consisted of the following primary components: a structural steel test frame assembly, test apparatus, and a data acquisition system. • The test frame consisted of horizontal (a post-tensioned concrete grade beam) and vertical (a structural steel tower) reaction elements, a rigid structural steel base, a load cap member, a mechanical motion multiplier (lever arm), guide tracks, and miscellaneous test fixtures. • The test apparatus consisted of a hydraulic actuator and accumulators, a Mediamation control system, a Baldwin 20,000-lb. compression-tension load cell, deflection LVDT’s, and linear motion transducers. • The data acquisition system consisted of an IBM compatible computer system, National Instruments data acquisition hardware, and National Instruments data acquisition software (LabView). Figure 2 presents a sketch showing the instrument locations on the test specimen. IX. TEST SETUP AND PROCEDURE The test apparatus was set-up in general conformance with Figure 2 of the SEAOSC Standard Method. The shear walls were positioned onto the test frame and attached as follows: At the Rigid Test Frame Base: The Simpson holdowns were connected to the rigid base of the

test frame to resist uplift forces. Threaded rods (7/8-in. diameter – ASTM A193-Grade B7) were extended through the frame base and were secured with a plate washer and nut to the bottom of the test frame. Three bottom track anchors (5/8-in. diameter) were installed through the bottom track of the steel framed wall and the rigid base and were secured with a plate washer and nut to the bottom of the test frame. At the Top of the Test Frame: A steel loading beam (load cap) connected the shear wall to the load cell. The load cap was fastened to the test panel with 7 - 1/4” self-drilling screws and 7 – 1/2-in. diameter bolts installed through the load cap into the top track of the wall. The load cell to load cap connection was made with a high strength threaded rod. The load cell was connected to the mechanical motion multiplier via a swivel adapter mechanism. Cyclic force was delivered to the panel with the hydraulic actuator and accumulators via the loading beam. Force at the top of the panel was measured with the compression-tension load cell. Displacement was measured with transducers set-up in general accordance with Section 7.6 of the SEAOSC Standard Method. The following displacement measurements were recorded: • • •

Horizontal displacement at the top of the panel - measured with a linear motion transducer. Vertical displacement at both end posts of the panel (uplift and compression) relative to the rigid base - measured with LVDTs. Horizontal displacement at the base of the panel relative to the rigid base (lateral in-plane sliding) - measured with an LVDT.

All shear walls were tested in accordance with the sequential phased displacement load procedure for shear walls as outlined in Table 1 of the SEAOSC Standard Method. A FME value 0.60-in. was selected based on panel height and from previous tests of shear walls sheathed with Sure-Board Structural Panels. The cyclic frequency for the initial stages of the test was 0.5-hz. The frequency was reduced to 0.3-hz., and 0.2-hz. at the later stages of each test. The data acquisition rate was 100-hertz. All specimens were tested to the end of the load scheme or until failure was observed. Figures 3 and 4 present photographs of the test apparatus and setup. X. TEST EQUIPMENT CALIBRATION The force and displacement transducers used in the racking shear test are calibrated annually. United Calibration, a NAVLP accredited calibration laboratory, calibrated the force and displacement transducers in September of 2006. The calibration instruments used by United Calibration are traceable to NIST. XI. FAILURE MODES The predominant failure mode observed was fastener withdrawal and shear failure. Post buckling was observed in test numbers 5 and 10. The specific failure mode of each test is noted on the Hysteresis Plots presented in Section 1 of the Appendix. Photographs of the failure modes are presented in Figures 5 and 6.
