C4.3.4-3 <br /> Shear = vh / 1000 Ga; Ga = vw / (vw / Gvtv + 0.75 en), from SDPWS Ex. C4.3.4-1. <br /> vw = ASD sheathing capacity. <br /> Gvtv = Shear stiffness from C4.3.4, shown in Sheathing Materials table. <br /> en = Nail slip from Table C4.2.3D of form aVn^b for WSP, constant for other materials. <br /> Vn = Shear force per nail along panel edge at ASD capacity vw. <br /> Hold – Anchorage system (hold-down) = da x h / beff. <br /> da = Vertical hold-down displacement; refer to Hold-down Displacement table for components. <br /> beff = Effective wall segment length = b - (tension stud pack width + hold-down anchor bolt offset) - (1/2 compression stud pack width) <br /> beff is given in the Shear Wall Dimensions table. <br /> For FTAO walls, hold-down device at end of wall is applied to all segments, as per APA T555. <br />Total Defl – Deflection from bending + shear + hold-down, as per Eqn. 4.3-2. <br /> For FTAO walls, the average of the values for the segments, as per APA T555. <br />14 <br />2726 W Strawberry Ln & <br />Unit# 23/17/2025
