Significance and Use5.1 SIPs are used as roof, wall,
14、 and floor components inbuilding structures. The structural performance properties needto be determined for design purposes.TEST METHODS6. Transverse Loads for Walls, Roofs, and Floors6.1 SIPs shall be tested in accordance with Methods E72,Section 11, with the following modifications:6.2 Support con

Shear Loads for Walls8.1 SIPs shall be tested in accordance with Methods E72,Section 14, with the following modifications:8.2 The SIP manufacturers method for attaching the SIPstogether and f
19、or attaching the SIPs to the top and bottom platesshall be followed. The SIPs shall not be attached to an externalprefabricated framework. Apply the load through the loadbeam to the top plate.8.3 Test Specimens:8.3.1 The test specimen shall be a minimum of 2.4 by 2.4 m(8 by 8 ft) consisting of a min

Boundary members shall be installed perthe manufacturers requirements at the ends of SIP assembly.See Fig. 2.9. Diaphragm
21、Loads for Floors or Roofs9.1 SIPs shall be tested in accordance with Method E 455with the following modifications:9.2 Cantilever Diaphragm and Simple Beam Diaphragm:NOTE 1The test assembly will be at least 2.4 by 4.8 m (8 by 16 ft) ifthe smallest element is 1.2 by 2.4 m (4 by 8 ft).9.2.1 Add to 4.1.
