1. What is the Australian Standards Ramp Calculator?

The Australian Standards Ramp Calculator determines if a ramp design meets the Australian standards for accessibility, which specify a maximum slope of 1:14 (approximately 7.1% gradient).

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

• \( Rise \) — Vertical height change
• \( Run \) — Horizontal distance

Explanation: The calculator compares the calculated slope against the Australian standard of 1:14 to determine compliance.

3. Importance of Ramp Slope Calculation

Details: Proper ramp slope calculation is crucial for accessibility compliance, ensuring safe and comfortable access for people with mobility impairments, wheelchair users, and those with strollers or carts.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run measurements. Both values must be positive numbers. The calculator will determine the slope ratio and check compliance with Australian standards.

5. Frequently Asked Questions (FAQ)

Q1: What is the maximum slope allowed by Australian standards?
A: The maximum slope for ramps according to Australian standards is 1:14 (approximately 7.1% gradient).

Q2: Are there different requirements for different types of ramps?
A: Yes, Australian standards may have specific requirements for different settings (public buildings, private residences) and ramp lengths. Always consult the latest Australian Standard AS 1428.1 for detailed requirements.

Q3: What other factors should be considered in ramp design?
A: Besides slope, consider landing areas, handrails, width, surface texture, and edge protection for comprehensive accessibility.

Q4: How is slope typically expressed?
A: Slope can be expressed as a ratio (1:14), percentage (7.1%), or angle (approximately 4.1 degrees).

Q5: Are there exceptions to the 1:14 standard?
A: Some exceptions may apply for existing buildings where space constraints prevent compliance, but new constructions should always meet the standard.
