⏺Includes self-weight of beams, slabs, columns, walls, and finishes.

⏺Does not change during building life.

⏺ACI Factor (USD): 1.2 × DL

🟥 Live Load (LL):

▶️Temporary or movable load.

📍Includes weight of people, furniture, vehicles, wind, or snow.

🔰Varies with usage or time.

▶️ACI Factor (USD): 1.6 × LL

✅ Design Load Combination (ACI 318): 1.2 DL + 1.6 LL

📘 Summary:

▶️DL = Permanent load (structure weight)

🎲LL = Variable load (occupancy & use)
