How much load does a roof carry?

Here, each square foot of roof system delivers 50 pounds of live load and 15 pounds of dead load (65 psf total) to the structural support system . Remember, these loads are distributed uniformly over the entire surface of the roof. The exterior wall (and the headers within) will carry all loads from the mid-point of the house (between the supporting walls) to the outside of the house (including the roof overhang). The distance in this case is 12 ft+ 2 ft = 14 ft. So, each lineal foot of wall must carry the loads imposed by a 1-foot wide strip in that 14 ft region. In technical terms, the wall has a tributary width of 14 ft. From this we can readily see that each lineal foot of wall supports:

Why is it important to list live load, dead load and total load separately?

It is important to list live load, dead load and total load separately because live load is used to compute stiffness and total load is used to calculate strength.

What is a distributed load?

Loads are considered to be either distributed or point loads. A layer of sand spread evenly over a surface is an example of a pure distributed load. Each square foot of the surface feels the same load. Live and dead loads listed in the building code for roofs and floors are approximations of distributed loads. Point loads occur when a weight is imposed on one spot in a structure, like a column. The load is not shared equally by the supporting structure. Analysis of point loading is best left to engineers. We will consider only distributed loads. This will enable us to size beams for most common applications.

How much does an 8 foot tall wall weigh?

Loads are contributed to the lower header by the roof, upper walls and 2nd floor system. 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 loads delivered to the header are:
