business and finance civil engineering industry# How is truss dead load calculated?

**load**from the total

**load**(total

**weight**). 235lbs. divided by 24-0-0 = 9.8 plf of uniform

**load**. Since the

**truss**is flat, we can apply half the uniform

**load**toeach chord member to account for the additional

**dead load**ofthe ½” gypsum.

Also asked, how do you calculate dead load?

You can **find out** the **dead load** per unitarea since the density of the concrete is known. In case you areinterested to **find out** the total **dead load** on theslab , just **find out** the area of the slab and multiply it bythe **Dead load** per square meter just calculated. Total**dead load** : 375*24 = 9000 Kg. or 9MT.

**dead load**of a

**typical**asphalt-shingled, wood-framed

**roof**is about 15 pounds persquare foot.

Simply so, 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.

**Laws of statics**

- are equal in magnitude;
- are opposite in direction; and.
- act along the line between the two points.

**Live loads** refer to the dynamic forces fromoccupancy and intended use. They represent the transient forcesthat can be moved through the building or act on any particularstructural element. The total **dead** plus **live loads**equal the “gravity **load**” of the structure. Butyet more **loads** act upon buildings, as well.
