This is the fourth video in the series on the timber framing code.
Floor load width calculator.
You can also use the wood beam calculator from the american wood council website to determine maximum rafter and joist lengths.
This video looks at floor load width flw.
Works with evenly distributed loads only.
Again this house has the same width dimension but it has 2 levels.
There are six choices.
A typical wood frame floor covered with carpet or vinyl flooring has a dead load of about 8 pounds per square foot.

Loads are contributed to the lower header by the roof upper walls and 2nd floor system.
Calculate the size needed for a beam girder or header made from no.
The architectural graphic standards lists the weight of an exterior 2 6 wall as 16 pounds per ft 2.
So an 8 foot tall wall weighs 8 ft x 16 pounds ft 2 128 pounds per lineal foot.
The top column labled span carried by beam determines the span supported by your beam.
Use the span tables below to determine allowable lengths of joists and rafters based on size and standard design loads.

Double check yourself with these span charts.

2 pine or lvl.
The supported length shown along the left most side of the table is the total length of the floor joists to be supported on either side of the floor beam divided by two.

The highest is a fully loaded floor 70 pounds per.
Also available for the android os.
Dividing by two gives us 12 feet of supported length.
In the case of our example house the house is 24 feet wide so the house will require a total width of 24 feet of joists.
The column on the left of each chart labeled beam span represents the beam length with bearing required for your project.
Flw is used to calculate the sectional size of.
We have engineered this calculator to provide spans which will produce a solid built house with no bounce in the floors or any swags in the ceiling.
