Scaffold Calculation Report

The Scaffold Calculation Report outlines the dimensions and components required for a scaffold measuring 10 m in length, 20 m in height, and 6 m in width, with a total of 48 standards, 66 ledgers, 66 transoms, 816 couplers, 200 planks, and 24 ties. The total load on the scaffold is calculated to be 25,676 kg, with a design load of 102,704 kg considering a safety factor of 4:1. The report ensures that the scaffold is designed to be stable and meets safety standards.

Scaffold Calculation Report

Given Dimensions:

- Length: 10 m

- Height: 20 m

- Width: 6 m

- Platform Spacing: Every 2 m vertically

Step 1: Definitions

1. Standards: Vertical tubes/poles that support the scaffold.

2. Ledgers: Horizontal tubes running parallel to the length of the scaffold.

3. Transoms: Horizontal tubes running perpendicular to the length, supporting the planks.

4. Couplers: Clamps that connect scaffold components.

5. Planks: Boards used for platforms.

6. Ties: Securing connections between the scaffold and a stable structure.

Step 2: Assumptions

- Standards are spaced every 2 m along both the length and width.

- Platforms are installed every 2 m in height (10 platforms total).

- Scaffold is double-row (standards in two rows along the width).

- Safety factor is 4:1.

Step 3: Scaffold Component Calculations

1. Standards:

- Standards are placed at grid intersections:


- Along length: (10 / 2) + 1 = 6

- Along width (2 rows): (6 / 2) + 1 = 4

- Total standards: 6 x 4 x 2 = 48

2. Ledgers:

- Ledgers run horizontally along the length.

- Levels (including top level): (20 / 2) + 1 = 11

- Ledgers per level (2 rows along the width): 6

- Total ledgers: 11 x 6 = 66

3. Transoms:

- Transoms run horizontally along the width to support planks.

- Transoms per level: (10 / 2) + 1 = 6

- Total transoms: 6 x 11 = 66

4. Couplers:

- Couplers connect standards, ledgers, and transoms:

- Standards to ledgers: 48 x 11 = 528

- Standards to transoms: 48 x 6 = 288

- Total couplers: 528 + 288 = 816

5. Planks:

- Plank width = 0.3 m.

- Platforms per level: (6 / 0.3) = 20

- Total planks: 20 x 10 = 200

6. Ties:
- Ties are placed every 4 m vertically and 3 m horizontally:

- Vertical tie levels: (20 / 4) + 1 = 6

- Horizontal ties per level: (10 / 3) + 1 = 4

- Total ties: 6 x 4 = 24

Step 4: Scaffold Load Calculations

1. Dead Load (Self-weight of Scaffold Components):

- Standards: 48 x 20 x 4.5 = 4,320 kg

- Ledgers and Transoms: (66 + 66) x 10 x 4.5 = 5,940 kg

- Couplers: 816 x 1 = 816 kg

- Planks: 200 x 25 = 5,000 kg

- Total Dead Load: 4,320 + 5,940 + 816 + 5,000 = 16,076 kg

2. Live Load (Workers, Tools, and Materials):

- Workers: 30 x 80 = 2,400 kg

- Materials and Tools: 1.2 x 60 = 7,200 kg

- Total Live Load: 2,400 + 7,200 = 9,600 kg

3. Total Load:

- Total Load = Dead Load + Live Load: 16,076 + 9,600 = 25,676 kg

4. Design Load:

- Design Load = Total Load × Safety Factor: 25,676 × 4 = 102,704 kg

Final Summary:

1. Standards: 48
2. Ledgers: 66

3. Transoms: 66

4. Couplers: 816

5. Planks: 200

6. Ties: 24

7. Total Load: 25,676 kg

8. Design Load (with Safety Factor): 102,704 kg

This sequence ensures the scaffold is properly designed, stable, and meets safety standards.
