Bearing walls use the double top plates to transfer loads from joists above through the wall studs, through the sole plates, through the floor system to the beams, columns, foundations and footings. Joints in top plates have to be located over the studs. The top and bottom double plate should not both have joints over the same stud. Joints in the top plates should be offset by at least one stud.
Holes or notches in top plates of bearing walls must have 2 inches of material intact, or the top plate should be reinforced with wood or metal.
If the floor or roof joists resting on the stud wall have the joists line up directly over or within 2 inches of the studs, a double top plate is not required, since there will be no load on the plate other than at the tops of studs. As a practical matter, this is rarely done, since it requires considerable care and layout. There is often a reason to move a joist one way or another slightly, and the double top plate provides the flexibility to do that.
If single top plates are used, the builder didn't use the double overlap method to lock wall corners and T intersections together. In this case, metal ties are used to secure the walls together. Metal ties are also used where lintels extend up flush with the top plate. This interrupts the continuity of the plate, and metal ties join each end of the lintel to the adjacent plate.
While we don't need double top plates on partition walls, these are common for a couple of reasons:
- Partition walls can be secured to and brace loadbearing walls by overlapping the double top bearing plates, locking the walls together.
- It is easier to cut all studs the same length to end up with an 8 foot high wall rather than to cut studs 1 1/2 inches shorter for bearing walls than for partition walls. It's faster and cheaper to build everything the same way.
Openings in bearing walls require lintels (horizontal beams) to carry the loads around the openings. Openings in partition walls do not need lintels.

What is an accretionary wedge?
An accretionary wedge is the accumulation of sediment formed by an oceanic plate and a tectonic plate, as it is scraped from the top of the oceanic plate.
When an oceanic plate collides with a continental plate the oceanic plate is usually subducted because?
with all that water pushing down on the plate, one of the plates has to go under. the one that is sliding under the top plate is usually the one that goes under. <3 hope this helps:)
When two plates collide what determines which plate comes out on top?
The more dense plate subducts (goes under) the less dense plate. For example if continental and oceanic crust collide oceanic crust will go underneath the continental.
What processes occur at plate edges?
Most tectonic activity takes place at a plate's edge or boundary. A plate moves as a single piece across the plastic top of the earth's mantle.
How can folding and faulting form mountains?
Folding and Faulting usually work together to form mountains. Faulting works by one plate shifting up and one plate submerging. Folding however works by both plates pushing against each other slowly folding over and over. Faulting and Folding and work together to make mountains by as one plate moves down the other up causes the plate going up to roll over or move on top of the other plate then as the bottom plate gets heat from the earths core it rises folding the plate on top again to bring it even higher.

What are wall studs?
they run vertically from bottom plate to top plate or double plate in a dwelling built from lumber framing.

Why is there a double top plate on a wall?
The double plate gives added support to a load resting upon it, particularly if a vertical framing member is not directly below it. It also provides additional space for attaching wallboard after the ceiling drywall is installed.
What plate is Philippine?
in the top of the Australian plate
If looking at a license plate from New York is New York on top or bottom of plate?
For license plates in the state of New York, the top of the plate reads "New York". The bottom of the plate reads, "The Empire State".
What is the price of econo dentures, top plate only?

What is placed at the left of the plate or on the plate?
You place forks on the left side of the plate. A napkin may go on top of the plate.
How far from the edge of the table do you place your plate?
There is no set rule for the placement of a dinner plate, but a good host will set a salad or bread/roll plate to the top left and a soup bowl and plate can be placed upon the top of the dinner plate if desired. A glass of water and/or wine can be placed at the top right.
How do your remove a double action hinge door?
unscrew the plate at the bottom and slide lower end along the floor until the pin at the top can be clear of the indent at the top of the door. Now the door should be clear and unattached!
How do you cut rafters with different plate heights?
If the plate height gets higher increase the depth of the birds mouth that sits on the plate. The birds mouth is the notch cut out of the rafter that allows it to sit flat on the top of the plate. If the plate is low then you will need to place a packer on top of the plate.
How do you arrange soup bowls on a table?
When setting the table for a meal in which soup is the first course, the soup bowls are placed on top of the dinner plate. (Or on top of the salad plate, which is already on top of the dinner plate if salad is to follow the soup.)
Is New York written on the top or bottom of the license plate?
