Section 2305 — GENERAL DESIGN REQUIREMENTS FOR LATERAL FORCE-RESISTING SYSTEMS — 2025 California Building Code (Title 24, Part 2)

2305.1 General. ¶

2305.1 General. Structures using wood shear walls or wood diaphragms to resist wind or seismic loads shall be designed and constructed in accordance with AWC SDPWS and the applicable provisions of Sections 2305, 2306 and 2307. 2305.1.1 Openings in shear panels. Openings in shear panels that materially affect their strength shall be detailed on the plans and shall have their edges adequately reinforced to transfer all shearing stresses. 2305.1.2 Permanent load duration. Permanent loads are associated with permanent load duration in accordance with the ANSI/AWC NDS. For wood shear walls and…

2305.2 Diaphragm deflection. ¶

2305.2 Diaphragm deflection. The deflection of wood-frame diaphragms shall be determined in accordance with AWC SDPWS. The deflection (Δ dia ) of a blocked wood structural panel diaphragm uniformly fastened throughout with staples is permitted to be calculated in accordance with Equation 23-1. If not uniformly fastened, the constant 0.188 (For SI: 1/1627) in the third term shall be modified by an approved method. Equation 23-1 Δ dia = 5 vL [3] /8 EAW + vL /4 Gt + 0.188 Le n + Σ( x Δ c )/2 W For SI: Δ dia = 0.052 vL [3] / EAW + vL /4 Gt + Le n /1627 + Σ( x Δ c )/2 W where: A = Area of chord…

2305.3 Shear wall deflection. ¶

2305.3 Shear wall deflection. The deflection of wood-frame shear walls shall be determined in accordance with AWC SDPWS. The deflection (Δ sw ) of a blocked wood structural panel shear wall uniformly fastened throughout with staples is permitted to be calculated in accordance with Equation 23-2. Equation 23-2 Δ sw = 8 vh [3] / EAb + vh /4 Gt + 0.75 he n + d a h / b For SI: Δ sw = vh 3 3EAb⁄ + vh Gt⁄ + -----------407.6 he n - + d a h b⁄ where: A = Area of end-post cross section in square inches (mm [2] ). b = Shear wall length, in feet (mm). d a = Total vertical elongation of wall anchorage…
