Transcribed Image Text:### Structural Grid Layout Diagram (P2.3)
#### Overview:
This diagram represents a structural grid layout commonly used in architectural and construction planning.
#### Elements Description:
1. **Columns**:
- The columns are indicated by circular markers labeled 1, 2, 3 vertically, and A, B, C horizontally.
- Each intersection of these labels (e.g., A-1, B-2, C-3) marks the position of a column.
2. **Beams**:
- Beams are denoted by alphanumeric labels such as B1, B2, B3, B4, G1, G2, G3, and G4.
- Vertical beams (e.g., B1, B2, B3, B4) run up and down between horizontal column lines.
- Horizontal beams (e.g., G1, G2, G3, G4) run left to right between vertical column lines.
#### Dimensions:
1. **Horizontal Dimensions**:
- The horizontal distance from point 1 to point 3 is segmented into six parts, each measuring 6.67 feet, therefore the total spans 40 feet.
- The first two sections from vertical line A to C span 20 feet each (3 segments of 8 feet for the total of 40 feet).
2. **Vertical Dimensions**:
- The vertical distance from line C4 to line C1 is segmented into five parts, each measuring 8 feet, therefore the total spans 40 feet.
- An additional vertical segment between C2 and C4 measures 2 sections at 10 feet each, thus totaling 20 feet.
#### Structural Grid Labeling:
- **Column Grid**:
- Row A: Points A-1, A-2, A-3
- Row B: Points B-1, B-2, B-3
- Row C: Points C-1, C-2, C-3
- **Beam Grid**:
- Between A and B: Beam B2, Beam G1
- Between B and C: Beam G3, Beam G4, Beam G2, Beam B3
- Additional Grid lines for segmentation: B1, B4.
#### Visual Representation:
- The diagram utilizes parallel lines to represent beams and solid lines with hash marking the segments of the grid. Columns are usually visualized as
Transcribed Image Text:### Building Section Diagram
**Description:**
The diagram illustrates a section of a building with specific measurements and labeled columns. The building section is depicted as a rectangular structure subdivided into smaller rectangular sections.
**Diagram Breakdown:**
1. **Overall Structure:**
- The diagram features a large rectangle divided into six smaller rectangles arranged in three rows and two columns.
2. **Columns:**
- There are two vertical columns labeled C1 and C3.
- Column C1 is positioned on the right side border of the building section.
- Column C3 is located in the middle.
3. **Measurements:**
- The total height of the building section is given as \(3 \times 12' = 36'\).
- The width of the building section is divided into two parts:
- The left section measures 40'.
- The right section measures 20'.
**Notations:**
- The height is noted as “3 @ 12' = 36’”, indicating that the height is divided into three sections, each 12 feet tall.
- The text "Building Section" is written below the diagram.
- The figure is labeled "P2.7" at the bottom center of the diagram.
This diagram is useful for visualizing and understanding architectural plans, allowing for precise identification of structural components and their dimensions.
