BRACED WALL PANELS (CRC CHAPTER 6)

SJ-MC tit. 24, ch. 24.09, pt. 3
in effect

San José Municipal Code § 24.09.310 Findings.

24.09.310 - Findings. The amendment set forth in Parts 1 and 2 of this chapter is reasonably necessary because of the following local geological and topographical conditions: A. San José is within a very active seismic area. B. Gypsum wallboard and exterior Portland cement plaster have performed poorly during recent California seismic events. C. The shear values for gypsum wallboard and Portland cement stucco contained on the code are based on monodirectional testing. D. The limitation on the use of these systems as set forth in the amendment until cyclic loading testing are performed and evaluated is a more restrictive standard which will better prevent damage which can result from local conditions. (Ord. 28838.)

San José Municipal Code § 24.09.330 Wall Bracing (CRC Section R602.10 Table R602.10.3(3)).

24.09.330 - Wall Bracing (CRC Section R602.10 Table R602.10.3(3)). CRC Section R602.10 Table R602.10.3(3) is amended to read as follows: Table R602.10.3(3) BRACING REQUIREMENTS BASED ON SEISMIC DESIGN CATEGORY [image omitted; see the official code] [image omitted; see the official code] For SI: 1 foot = 304.8 mm, 1 pound per square foot = 47389 Pa. NP = Not Permitted a. Linear interpolation shall be permitted. b. Interpolation of bracing length between the Sds values associated with the seismic design categories shall be permitted when a site specific Sds value is determined in accordance with Section 1613.2 of the California Building Code. c. Where the braced wall line length is greater than 50 feet, braced wall lines shall be permitted to be divided into shorter segments having lengths of 50 feet or less, and the amount of bracing within each segment shall be in accordance with this table. d. Methods PFG and CS-SFB do not apply in Seismic Design Categories D0, D1 and D2. e. Methods PFH, PFG and ABW are only permitted on a single story or a first of two stories. f. Where more than one bracing method is used, mixing methods shall be accordance with section R602.10.4.1. g. One- and two-family dwellings in Seismic Design Category D2 exceeding two stories shall be designed in accordance with accepted engineering practice. (Ords. 28838, 29334, 30326, 30837.)

San José Municipal Code § 24.09.340 Section R602.10.8.1.

24.09.340 - Section R602.10.8.1. CRC Section R602.10.8.1 is amended to read as follows: 602.10.8.1 Braced wall panel connections for Seismic Design Categories D0, D1, and D2. Braced wall panels shall be fastened to required foundations in accordance with Section R602.11.1, and top plate lap splices shall be face-nailed with not less than eight 16d nails on each side of the splice. Wall sheathing shall not be attached to framing members by adhesives. All braced wall panels shall extend to the roof sheathing and shall be attached to parallel roof rafters or blocking above with framing clips (eighteen-gauge minimum) spaced at maximum twenty-four inches (6,096 mm) on center with four 8d nails per leg (total eight 8d nails per clip). Braced wall panels shall be laterally braced at each top corner and at maximum twenty-four-inch (6,096 mm) intervals along the top plate of discontinuous vertical framing. (30326.)
