. 1. Determine appropriate live and dead load,and the load duration factor. • Table is based on:
2. If your slope is 6:12 or less,use the Low slope column.If it is between 6:12 — Minimum bearing length of 1%"end and 3'h"intermediate,without web stiffeners.
and 12:12,use the High column. — Uniform loads.
— More restrictive of simple or continuous span.
3. Scan down the column until you find a span that meets or exceeds the span — Minimum roof slope of 1/4:12.
of your application.
• Total load values are limited to deflection of L/180 and live load is based on joist
4. Select T116 joist and on-center spacing. deflection of L/240.
• A support beam or wall at the high end is required.Ridge board applications do not
provide adequate support.
