Ground Snow Load, pg : 20 Ib/ft
Mapped Elevation: 417.8 ft
Data Source:
Statutory requirements of the Authority Having Jurisdiction are not included.
Snow load values are mapped to a 0.5 mile resolution. This resolution can
create a mismatch between the mapped elevation and the site -specific
elevation in topographically complex areas. Engineers should consult the local
authority having jurisdiction in locations where the reported `elevation' and
`mapped elevation' differ significantly from each other.
The ASCE Hazard Tool is provided for your convenience, for informational purposes only, and is provided "as is" and without warranties of any
kind. The location data included herein has been obtained from information developed, produced, and maintained by third party providers; or
has been extrapolated from maps incorporated in the ASCE standard. While ASCE has made every effort to use data obtained from reliable
sources or methodologies, ASCE does not make any representations or warranties as to the accuracy, completeness, reliability, currency, or
quality of any data provided herein. Any third -party links provided by this Tool should not be construed as an endorsement, affiliation,

Notes:
7. Capacity has been reduced by a factor of 0.92 because of the use of hold-downs on walls with 10d nailing, as per Table 4.3A Note 10.
5. This material does not contribute to seismic shear resistance because the Design setting for ignoring contribution was set.

FHS — Depending on element, shows different definitions of full -height sheathing length (FHS):
Shear lines with multiple walls, segmented walls, or FTAO walls: Total shear -resisting FHS
Individual wall segments or walls without openings: Distance between hold-downs beff
Perforated walls: Sum of factored segment lengths bi defined in SDPWS 4.3.5.6
Aspect Ratio — Ratio of wall height to segment length (h/b); for FTAO walls, the aspect ratio of the central pier
Wall Group — Wall design group defined in Sheathing and Framing Materials tables, where it shows associated Standard Wall
Studs: Number of end studs at the south and north or west and east ends of a wall segment or a perforated or FTAO wall.

Block - Block used in load generation
Accum. = loads from one block combined with another
Manual = user -entered loads (so no block)
F - Building face (north, south, east or west)
Element - Building surface on which loads generated or entered
Load Case - One of the following:
ASCE 7 All Heights: Case 1 or 2 from Fig 27.3-8 or minimum loads from 27.1.5
ASCE 7 Low-rise: Reference corner and Case A or B from Fig 28.3-1 or minimum loads from 28.3.4
Wind Dir - Direction of wind for loads with positive magnitude, also direction of MWFRS.
Surf Dir - Windward or leeward side of the building for loads in given direction
Prof - Profile (distribution)
Location - Start and end points on building element
Magnitude - Start = intensity of uniform and point loads or leftmost intensity of trapezoidal load, End = right intensity of trap load
Trib Ht - Tributary height of area loads only
Notes:
All loads entered by the user or generated by program are specified (unfactored) Ioads.The program applies a load factor of 0.60 to wind loads
before distributing them to the shearlines.

Design = The greater of the story shear and Fpx + transfer forces from discontinuous shearlines, factored by overstrength (omega) as per
12.10.1.1. Omega = 3.0 as per 12.2-1.
Redundancy Factor p (rho):
E-W 1.00, N-S 1.30
Automatically calculated according to ASCE 7 12.3.4.2.
Applies to shearwall design, hold-down forces and the drag strut force component based on shearline forces; does not apply to story drift, out -of -
plane force, or the diaphragm force Fpx and the drag strut force component based on it.

critical for all walls in the Standard Wall group.
For Dir - Direction of seismic force along shearline.
v - Design shear force on segment = ASD-factored shear force per unit length of full -height sheathing (FHS)
vmax/vft - Perforated walls: Collector and in -plane anchorage force as per SDPWS eqn. 4.3-9 = V/FHS/Co. FHS is factored for narrow segments as
per 4.3.3.4
FTAO walls: Shear force in piers above and below either openings or piers beside opening(s). Aspect ratio factor does not apply to these piers.
V - ASD factored shear force. For shearline: total shearline force. For wall: total of all segments on wall. For segment: force on segment
Asp/Cub -For wall: Unblocked structural wood panel factor Cub from SDPWS 4.3.5.3. For segment or FTAO pier: Aspect ratio factor from SDPWS
4.3.5.5.1. For perforated wall: Either Cub or sum bi / FHS, where bi is segment length adjusted per SDPWS 4.3.3.4.
Int, Ext - Nominal unit shear capacity of interior and exterior sheathing, factored by Table 4.3-1 Note 3 for framing specific gravity and Note 10 for
presence of hold-downs. For wall segments, also include unblocked factor Cub and aspect ratio adjustments.
Co - Adjustment factor for perforated walls from SDPWS Equation 4.3-6.
C - Sheathing combination rule, A = Add capacities, S = Strongest side or twice weakest, G = Stiffness -based using Eqns. 4.3-3,-4.
Cmb - Combined interior and exterior unit shear capacity including perforated wall factor Co.
V - Total factored shear capacity of shearline, wall or segment.
Crit Resp - Response ratio = v/Cmb = design shear force/unit shear capacity. "W" indicates that the wind design criterion was critical in selecting
wall.
Notes:
Refer to Elevation View diagrams for individual level for uplift anchorage force t for perforated walls given by SDPWS 4.3.6.4.2,1.
The contribution to shear resistance from gypsum, fiberboard, or lumber sheathing is taken as zero because of the Design setting for ignoring
contribution was set. Refer to the Sheathing Materials table for the wall groups affected.

1. Nominal unit shear capacities shall be adjusted in accordance with 4.2.3 to determine
ASD allowable unit shear capacity and LRFD factored unit resistance. For general
construction requirements see 4.2.6. For specific requirements, see 4.2.7.1 for wood
structural panel diaphragms. See Appendix A for common nail dimensions.
2. For species and grades of framing other than Douglas -Fir -Larch or Southern Pine,
reduced nominal unit shear capacities shall be determined by multiplying the
tabulated nominal unit shear capacity by the Specific Gravity Adjustment Factor =
[ I-(0.5-G)], where G = Specific Gravity of the framing lumber from the NDS (Table
12_33A)_ The Specific Gravity Adjustment Factor shall not be greater than 1.
3. Apparent shear stiffness values, G„ are based on nail slip in framing with moisture
content less than or equal to 19 % at time of fabrication and panel stiffness values
for diaphragms constructed with either OSB or 3-ply plywood panels. When 4-ply
or 5-ply plywood panels or composite panels are used, G. values shall be permitted
to be multiplied by 1.2.
4. Where moisture content of the framing is greater than 19 % at time of fabrication,
G. values shall be multiplied by 0.5.
5. Diaphragm resistance depends on the direction of continuous panel joints with respect
to the loading direction and direction of framing members, and is independent of
the panel orientation.

3.2.2 Floor Sheathing
Floor sheathing shall be capable of resisting and
transferring gravity loads to the floor framing. Sheath-
ing used in diaphragm assemblies to resist lateral forces
shall be designed in accordance with 4.2.
3.2.3 Roof Sheathing
Roof sheathing and its fasteners shall be capable of
resisting and transferring wind and gravity loads to the
roof framing. Maximum spans and nominal uniform
load capacities for roof sheathing materials are given in
Table 3.2.2. The ASD allowable uniform load capaci-
ties to be used for wind design shall be determined by
dividing the nominal uniform load capacities in Table
3.2.2 by an ASD reduction factor of 1.6. The LRFD
factored uniform load capacities to be used for wind
design shall be determined by multiplying the nominal
uniform load capacities in Table 3.2.2 by a resistance
factor, Ob, of 0.85. Sheathing used in diaphragm as-
semblies to resist lateral forces shall be designed in ac-
cordance with 4.2.

I . Nominal capacities shall be adjusted in accordance with Section 3.2.3 to determine ASD uniform load capacity and LRFD uniform resistances.
2. Unless otherwise noted, tabulated values are based on the lesser of nominal values for either OSB or plywood with 3 or more plies.
3. Tabulated values are based on the lesser of nominal values for either OSB or plywood with 4 or more plies.
4. Tabulated values are based on the lesser of nominal values for either OSB or plywood with 5 or more plies_
5. Wood structural panels shall conform to the requirements for its type in DOC PS 1 or PS 2.
6. Tabulated values are for maximum bending loads from wind. Loads are limited by bending or shear stress assuming a 2-span continuous condition. Where
panels are continuous over 3 or more spans, the tabulated values shall be permitted to be increased in accordance with the .ASD/LRFD Manual for Engineered
Wood Construction.
7. Strength axis is defined as the axis parallel to the face and back orientation of the flakes or the grain (veneer), which is generally the long panel direction, unless
otherwise marked.
