Note:

The Total Dead Load (DL) is the total weight of all scaffold components. It ensures the **scaffold structure is safe** and can support additional loads.

• Wₛ (Standards): Vertical pipes that bear the main load. These are typically made of steel or aluminum pipes.
  Example: Steel pipes with a diameter of 48 mm and thickness of 3 mm. If each steel pipe weighs 10 kg and there are 10 standards, the total weight of standards is 100 kg (10 kg x 10).
• Wₗ (Ledgers): Horizontal members connecting the standards. These are usually made of steel, aluminum, or wooden beams.
  Example: Steel I-beams or tubular steel members, each weighing 5 kg. If there are 8 ledgers, the total weight of ledgers is 40 kg (5 kg x 8).
• Wₜ (Transoms): Cross beams supporting platforms. Transoms are typically made of steel, aluminum, or sometimes wood.
  Example: Tubular steel transoms with a weight of 8 kg each. If there are 6 transoms, the total weight of transoms is 48 kg (8 kg x 6).
• Wₚ (Platforms): Wooden planks or metal decks where workers stand. These are often wooden planks or steel grating, depending on the design of the scaffold.
  Example: Wooden planks measuring 2 meters in length and 20 cm in width, each weighing 15 kg. If there are 4 platforms, the total weight of platforms is 60 kg (15 kg x 4).
• Wₐ (Accessories): Brackets, clamps, guardrails, and other components. Accessories can include items like couplers, pins, braces, and safety guardrails, all of which add to the overall weight.
  Example: Steel clamps weighing 2 kg each. If there are 12 accessories, the total weight of accessories is 24 kg (2 kg x 12).

Why is this important?

• Ensures **scaffolds can safely support additional loads** (workers, tools, materials).
• Helps prevent **structural failures and overloading accidents**.
• Aids in **engineering calculations for safe scaffold design**.
