Transcribed Image Text:**Designing a Rectangular Beam for an Office Building**
### Diagram Overview:
The diagram illustrates a simple floor plan layout with two sections:
- Dimensions: 20' for the first section, 26' for the second section, with a 25' span labeled as AB.
### Design Specifications:
- **Objective**: Design a rectangular beam with a 25' simple span along AB.
- **Concrete Compressive Strength (\(f'_c\))**: 3000 psi
- **Steel Yield Strength (\(f_y\))**: 60,000 psi, Normal Weight Concrete (NWC)
### Load Details:
- **Dead Load**: 94 psf (not including the beam weight)
- **Live Load**: 50 psf for an office building
### Beam Cross-Section:
- **Dimensions**: Depth = 30", Width = 14"
- **Reinforcement Specification**:
- Minimum cover of 1.5"
- Use #4 stirrups
This design setup is tailored for structural engineers planning the reinforcement of concrete beams in office buildings, addressing safety and load-bearing requirements.
