The first kind of wall which carries the weight of the structure and supports the roof is known as a load bearing wall.
Flat roof load bearing wall.
The standard guide in the u s the asce 7 05 lists weights and stresses for all building materials expressed in pounds per square foot.
A gable roof is a roof that slopes downward from a central ridge to a building s exterior walls on two sides.
Due to the triangular shape of all but flat roofs the rafters or joists will run perpendicular to the roof ridge as well as to load bearing walls.
In this roof design the exterior walls on which the roof s sloping rafters rest are load bearing walls.
A wall that is set directly over one of those beams is probably not a load.
This makes load bearing walls a key structural element of any building.
Load bearing walls support the weight of a floor or roof structure above and are so named because they bear a load.
Load bearing walls cross roof beams in a perpendicular direction.
These walls transfer the vertical load of the house straight to the foundation or some other element that undergirds it.
Load bearing or primary structure usually constructed in timber in a residential construction.
Use this clue to narrow down possible load.
Roof and wall sheathing gravity and wind loads floor diaphragms and shear walls.
By contrast a non load bearing wall sometimes called a partition wall is responsible only for holding up itself.
The roof trusses are too long to span the whole house so the load bearing wall runs down the center of the house to support the trusses at the perpendicular intersection in the middle.
On the other two sides the roof terminates in a flat triangular gable.
The construction of the flat roof is similar to that of the timber upper floor.
Ways to identify a load bearing.
If a wall is located on the ground floor go down to the basement to observe the ceiling beams.
Calculating the load on a flat roof is a challenging task for the layperson that involves knowledge of building materials their weights and local building codes.
