We'll start with a flat truss: The trussis 24-0-0 in length and 4-0-0 tall. Multiply the Span by the Heightto calculate the area: 24ft x 4ft = 96 sq-ft. area. Multiplythat by the weight of our material (2psf), and we get atotal weight of 192 lbs.

Correspondingly, how much does a roof truss weigh?

For wood trusses with a total load of around 180pounds per lineal foot (30 pounds per square foot spaced one at sixfoot or two at 12 feet), a single 24 foot span 4/12 slope trussweight should be about 125 pounds.

Also, where is the load on a truss? In trusses loaded by downward forces, the members alongthe top (the “top chord”) are in compression and themembers along the bottom (the “bottom chord”) are intension.
