Determine the amount of rebar needed for the foundation walls shown in the figures. Allow for two inches of cover. Add 10 percent for lap and waste to the continuous bars. Horizontal and vertical rebars should be "#4 Rebar @ 12" O.C Bothways".
Transcribed Image Text:The diagram illustrates a portion of a reinforced concrete structure with specifications for dowels and rebar placement.
- **Structure Dimensions**: The total height of the structure is 12 feet. The bottom section, resembling a base, is 3 feet wide and 1 foot 3 inches tall, located at the base of the structure.
- **Rebar Details**:
- The base contains 5 pieces of continuous #4 reinforcing bars (rebar).
- Additional #4 rebar is placed at 12-inch on-center (O.C.) spacing.
- **Dowels Specifications**:
- #5 dowels are placed at 12-inch O.C., alternating directions, along the vertical section of the structure.
- These dowels extend from the base into the vertical element, which also rises 12 feet high, spaced 1 foot apart horizontally.
This setup describes a typical reinforcement plan for vertical and horizontal elements in a concrete structure, illustrating how reinforcements are integrated to provide structural stability and integrity.
Transcribed Image Text:The image depicts a floor plan with dimensions provided.
- The overall outer rectangle measures 40 feet in width and 30 feet in height.
- Inside this larger rectangle, there is a smaller rectangular section located in the upper right corner.
- This smaller rectangle has its bottom edge positioned 18 feet from the left side of the larger rectangle.
- Additionally, the left edge of the smaller rectangle is positioned 12 feet from the top of the larger rectangle.
The floor plan consists of dashed lines indicating the boundaries of both the larger and smaller rectangles, providing a clear visual representation of their placement and dimensions within the space.
