a long concrete bearing wall has vertical expansion joints placed every 40 feet. Determine the required width of the gap in a joint if it is wide open at 32°F and just barely closed at 90°F. Use the thermal expansion coefficient /°F. The solution must include equations, procedures, final calculated width, and units

Transcribed Image Text:### Concrete Bearing Wall with Expansion Joints
#### Diagram Overview
The diagram illustrates a section of a concrete bearing wall incorporating expansion joints. The wall is segmented into equal sections, each measuring 40 feet in length.
#### Detailed Description
- **Concrete Bearing Wall**: This is the main structure shown in the diagram, providing support and stability. It is depicted as a long, rectangular block divided into segments.
- **Expansion Joints**: Positioned between each 40-foot segment of the wall, these joints are crucial in accommodating temperature-induced expansion and contraction. This prevents cracks and structural damage over time.
#### Important Points
- **Segment Length**: Each segment of the concrete wall measures 40 feet, for a total of three segments shown.
- **Purpose of Expansion Joints**: They allow for movement due to thermal expansion and contraction, ensuring the integrity of the structure.
This design is essential in large concrete structures to maintain durability and prevent cracking.
