Load Bearing Concrete Wall Design

Weight of 10dt24 468 plf roof dead load 20 psf roof live load 30 psf wind load 30 psf the 10dt24 are spaced 5 ft on center.

Load bearing concrete wall design.

While cracks in a slab may not seem like a big deal the smallest crack represents a large amount of downward pressure that may be crushing pipework beneath. Capacity strength of reinforced concrete. Axial load bending moment interaction diagrams. Precast concrete bearing wall panel design alternative design method using aci 318 11 a structural precast reinforced concrete wall panel in a single story building provides gravity and lateral load resistance for the following applied loads.

The precast concrete wall can be used as load bearing structures and will save costs by eliminating the need for an additional structural framing system. Example of one factored load combination. R l 20 psf. Should i account for an eccentricity or can i assume that the load is imparted concentrically on.

This line load is imparted by the slab that the wall is supporting. F y 60000 psi. An important part of the detail is the connection at the top of the beam to the panel. H 8 in.

This connection is used for erection and to positively tie the beam to the panel. Structural design of buildings requires a variety of structural loads to be accounted for. The materials most often used to construct load bearing walls in large buildings are concrete block or brick. A load bearing wall or bearing wall is a wall that bears a load resting upon it by conducting its weight to a foundation structure.

Live loads equipment load factors strength reduction factor varies from 0 90 for bending to 0 75 for shear. Knowing the load bearing capacity of your concrete is essential to make sure that what you plan to have supported by the wall or slab will not be too heavy and cause it to crack and break. Weight of 10dt24 468 plf roof dead load 20 psf roof live load 30 psf wind load 30 psf the 10dt24 are spaced 5 ft on center. Load factor for backfill resisting full manure case is 0 90.

φu 1 2d 1 6h 1 6l. A rc exterior wall supporting a two story building. Several design approaches are available for combined axial compression. Precast concrete walls can be designed to be reused for future building expansions.

Load bearing walls review equation and wall stud spacing design table. I have a bearing wall taking a line load at the top. Aci 318 05 section 14 5. Precast concrete s durability creates a low maintenance structure which stands up to harsh climate conditions.

A structural precast reinforced concrete wall panel in a single story building provides gravity and lateral load resistance for the following applied loads. L c 12 ft. Compression strength of concrete. My very limited experience in concrete is showing as i struggled to design a simple bearing wall today.

F c 3000 psi.
