Span Calc vs Builder's Helper MAX使用状況と統計
The American Wood Council (AWC) Span Calculator for Wood Joists and Rafters (Span Calc) performs calculations for all species and grades of commercially available softwood and hardwood lumber as found in the 2021 National Design Specification® (NDS®) for Wood Construction. Joists and rafter spans for common loading conditions can be determined. A span options calculator allows selection of multiple species and grades for comparison purposes.
Supported by the Softwood Lumber Board.
Maximum horizontal spans for joists and rafters are calculated based on the following assumptions and conditions:
· Joists and rafters are oriented to support vertical loads applied to the narrow (1.5 in. thick) face of the member, resulting in strong-axis bending.
· At least three joists or rafters are installed parallel to one another and spaced not more than 24 inches on-center, with properly designed sheathing attached on the top (compression) edge of each joist or rafter.
· Joists and rafters are single-span with adequate structural support at each end. The Span Calculator does not address cantilevered joists and rafters, multiple-span joists and rafters, or spliced joists and rafters.
· For joists and rafters, most building codes specify a minimum bearing length of 1.5 inches on wood or metal and not less than 3 inches on masonry or concrete. These minimum bearing lengths are to be used in the absence of calculated bearing lengths. Consult the local building code for specific requirements.
· Joists and rafters carry only combinations of dead load plus live load (D + L), dead load plus snow load (D + S), or dead load plus roof live load (D + Lr). The Span Calculator does not address wind load or seismic load.
· Buildings in regions with ground snow loads greater than 70 psf should not use the prescriptive provisions of the governing building code without approval of the authority having jurisdiction. Buildings in these high snow zones should be designed in accordance with accepted engineering practice.
While every effort has been made to insure the accuracy of the information presented, and special effort has been made to assure that the information reflects the state-of-the-art, neither the American Wood Council nor its members assume any responsibility for any particular design prepared from this Span Calculator application. Those using this Span Calculator assume all liability from its use.

----
Features:
• Calculator: Includes all of the features you would expect to find on an advanced Construction Calculator, but redesigned and optimized for the touch screen.
Easily calculate linear, square & cubic measurements in English (Yards, Feet, Inches, Inch Fractions [up to x/128”]) & Metric (Millimeters, Centimeters, Meters), and convert easily between the two unit modes with a convenient [E/M] toggle.
Store & recall triangular measurements to calculate roof pitch, rafter lengths, stair lengths, and more with the convenient [Pitch], [Rise], [Run] and [Diagonal] buttons. When any 2 values are stored, the other 2 are generated automatically!
The [Tape] feature keeps an easy-to-read list of your calculations for error-checking, while the Memory Bank feature allows you to Add, Subtract, and recall stored values with a running ticker displayed in the LCD area.
Plus we just added a NEW Quick-List feature, which allows you to label and store often-used values for quicker entry into your equation!
• Notepad: Keep important notes within one tap of your calculator, supporting multiple pages and exporting to PDF.
• Projects:
Create lists of data in Text-Only, Simplified, or Detailed lists, and store in organized Projects. Useful for take-offs, estimating, budgets, material lists, etc. Lists can even be tabulated to include running totals on the bottom!
Not only does it keep track of important project info & create powerful lists, but you can also store project documents (like budgets, contracts, plans, etc.) & images (either by attaching images from you photo library or taking new ones).
And of course you can Print or export your Project data via email as a PDF!
• Quick-Jobs: Graphical interface to easily calculate all kinds of construction projects, large or small. With just a few known parameters, Quick-Jobs will automatically fill-in and calculate the rest of the project for you.
These Quick-Jobs are included:
-Rafters
-Stairs
-Arc/Circle
-Column/Cone
-Crown/Miter
-Concrete
-Conc. Block
-Drywall
-Flooring
-Painting
-Roof
-Convert
-Fencing (Imperial-Mode Only)
-Decking (Imperial-Mode Only)
-Wall Framing (Imperial-Mode Only)
-Board Feet Calc. (Imperial-Mode Only)
You can also export all of your QJ data to be included with a Project, or export separately.
