Roof Truss Design Loads

Live loads occupants and moveable objects in or on the structure dead loads weight of the building materials and the structure itself.

Roof truss design loads.

The live load shall be taken as follows. Live loads on roof trusses. I for sloping or flat roof with slopes up to and including 10 degrees. There are parallel and triangular and trapezoidal trusses.

How to order roof trusses successfully. A dead load is carried constantly by the truss. This includes all of the roofing material and ceiling along with loading for construction purposes and then environmental factors such as wind and snow. A when access is provided 1500 n m 2 b when access is not provided 750 n m 2 except for maintenance ii sloping roof with slope greater than 10 degrees.

Trusses are designed to carry two types of loads. Live loads and dead loads. A live load is a temporary load that puts stress on the structure. It s crucial that we factor in the proper truss load.

Both sides of the equation should be equal in order to end up with a stable and secure roof structure. Loads truss design there are different types of loads that act on structures. If the number of members is labeled m and the number of nodes is labeled n this can be written as m 3 2 n. After that the external load is to be estimated including the self load of the truss.

Live loads include wind precipitation foot traffic and all other weight that comes and goes. The amount of weight a truss needs to support per square foot is important.
