1. What is Ramp Slope Calculation?

Ramp slope calculation determines the incline of a ramp, which is crucial for accessibility compliance in Australia NSW. The slope is expressed as a ratio of rise to run (vertical height to horizontal length).

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height (meters)
• \( Run \) — Horizontal length (meters)

Explanation: The slope is calculated by dividing the vertical rise by the horizontal run. For accessibility ramps in NSW, the maximum allowable slope is typically 1:14.

3. Importance of Ramp Slope Calculation

Details: Proper ramp slope calculation is essential for compliance with Australian accessibility standards (AS 1428.1), ensuring safe and accessible environments for people with mobility limitations.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run in meters. Both values must be positive numbers. The calculator will provide the slope value and the 1:X ratio commonly used in accessibility standards.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum allowable slope for ramps in NSW?
A: For accessibility compliance, the maximum slope is typically 1:14 (approximately 7.1% gradient) for ramps up to 9m in length.

Q2: How is slope different from gradient?
A: Slope is expressed as a ratio (1:14), while gradient is expressed as a percentage (7.1%). Both represent the same incline but in different formats.

Q3: When are landings required on ramps?
A: Landings are required at the top and bottom of ramps, and at intervals not exceeding 9 meters for straight ramps or where the ramp changes direction.

Q4: Are there different requirements for existing buildings?
A: Yes, existing buildings may have different compliance requirements under the Disability (Access to Premises—Buildings) Standards 2010.

Q5: What other factors affect ramp design?
A: Handrails, width, surface texture, edge protection, and landing sizes are all important considerations in accessible ramp design.
