Fastener & factors preset or custom · Table 11.3.1

Fastener type

Bolt: enter D and F_yb per NDS Table I1. Lag screw: pick shank size (Table I1), then length. Wood screw: pick size (Table L3), then length (3–6 in. in 1/2 in. steps). Structural screw: capacity from manufacturer published data when on file. Pick C_D for the governing duration. This application does not evaluate ASCE load combinations. C_t = 1.0 assumed. Moisture at fabrication and in service selects C_M from NDS 2018 Table 11.3.3. For fabrication > 19% and in service ≤ 19%, C_M starts at 0.40. Check a footnote 2 condition to use 1.0. Nothing checks those boxes for you. The same C_M applies to setup Z′ and the group.

References & assumptions

ASD only — Wood Design: ANSI/AWC NDS-2018 Ch. 12 · Steel: AISC. Load Combinations: not evaluated (engineer-selected C_D only).

Reference Z from NDS Table 12.3.1A (min. of six yield modes); adjusted Z′ = Z × C_D × C_M × C_t × C_tn × C_Δ for a single laterally loaded fastener.

Verification required: Confirm all results against NDS 2018, AISC, and governing standards. Not a substitute for engineering judgment.

Z′ (single fastener, max)

—

Z′ = Z × C_D × C_M × C_t × C_tn × C_Δ (C_t = 1.0) for one fastener in this member configuration. Group C_M, C_g, and per-fastener Z′ are on the Spacing tab.

Minimum of modes I_m, I_s, II, III_m, III_s, IV (Table 12.3.1A, single or double shear) before load-duration and service adjustments.
