How many 2x12 will it take to resupport the ceiling plate of a 17-foot load bearing wall to be removed from between 2 12-foot rooms and how many vertical 2x4 more than three are needed on the ends?
Consult the services of a local structural engineer with experience in wood frame construction. It would be irresponsible to answer this question without detailed knowledge of the work proposed, local building codes or by anyone other than an engineer.
A "load-bearing" wall is typically defined as a wall supporting any vertical load in addition to its own weight. A shear wall transfers lateral loads from a roof, ceiling or floor diaphragm to a foundation or other element. Although a shear wall might not carry gravity loads from roof or floor forces, it can still be considered load-bearing as the lateral forces induce a rotational, or overturning moment in-plane with the wall, which results in…
What is the maximum span on a double 2x12 beam supporting 2x8 ceiling rafters and an acoustical ceiling?
Should you remove ceiling to install an interior non load bearing wall or can the top plate sandwich the ceiling wallboard between it and the ceiling joist?
All exterior walls in a home are load bearing. The exterior walls on the gable end of your house do not bear much load, but the walls that the hip of the roof bear on carry your roof and ceiling joints. Interior walls are another story. Usually in a smaller one story home there is a wall that runs the midspan of the house that is load bearing for your roof and ceiling joints.
Is it possible to offset a p-trap in a shower so that it does not conflict with a recessed light in the ceiling below?
Non-load-bearing walls support only themselves; they are interior partition walls. They have a single top plate. While non-load-bearing walls might run perpendicular to floor and ceiling joists, they will not be aligned above support beams. As the name implies, load-bearing walls carry the structural weight of your home. Load-bearing walls in platform-frame homes will have double top plates. That is, two layers of framing lumber. Note: all exterior walls are load bearing; I got this…
Yes a suspended ceiling can be installed at a reasonable angle. Please note that the closer to vertical the harder it is to place the panels in the grid. There is also greater difficulty in installing the grid. When the grid is horizontal a simple level is all that is required to insure proper installation. If installed on an angle other more advanced method are required.
Fire divisions are determined by fire walls. A space divided by a fire wall would be two divisions. Each fire-rated floor/ceiling structure would also create additional vertical fire divisions. For example, if you have a two-story building with fire separation between floors (and on vertical openings, such as stairs and elevators), and each floor had two fire walls, dividing the floor area into three divisions, you would have a total of six fire divisions.
Definition of a "Flying Buttress" A vertical stone arch support(normally in a cone or pyramid shape) , sticking (or extends, "flies") out from the roof to a pier, to keep vertical pressure, enhancing stability. Normally hidden. Allows creation of high ceiling walled churches typical of Gothic Architecture. -Bernay.
There are lots of reasons this may be true. I suspect the biggest reason is that somewhere on that floor is the heating and cooling equipment, water heating, etc. and the ceiling height is necessary for that equipment. If this is true then you also have the bulk of your ducts, water pipes, etc. in the ceiling of the ground floor and these are often run between an artificial drop ceiling and the actual structural…
