**Figure Description:**
1. **Beam Diagram:**
   - A horizontal beam is shown with equidistant vertical lines along its length, indicating supports or points of interest.
   - Beam length: 16 feet.

2. **Cross-Section Diagram:**
   - Cross-section width: 12 inches.
   - Cross-section height: 22 inches.
   - Reinforcement details: 4 rebars labeled as #8.
   - Cover from outer edge: 1.5 inches.

**Calculations and Parameters:**
- **Dead Load (W<sub>DL</sub>):** 2.0 kips per linear foot (klf), including self-weight.
- **Construction Load (W<sub>CL</sub>):** 3.0 klf.
- **Concrete Specifications:**
  - Normal Weight Concrete (NWC).
  - Specified compressive strength (f'c): 4000 psi.
  - Yield strength of reinforcing steel (f<sub>y</sub>): 60 ksi.
  - Number of rebars: n = 8.

**Analysis Types:**
1. \( \delta_{DL} \) - Deflection due to Dead Load.
2. \( \delta_{LL} \) - Deflection due to Live Load.
3. \( \delta_{DL+LL} \) - Combined deflection from Dead Load and Live Load.
4. \( \delta_{\text{long-term}} \) - Long-term deflection after 4 years, assuming a continuous application of 25% of the live load for 48 months.
