1. What is the Viva Access Ramp Calculator?

The Viva Access Ramp Calculator calculates the slope of an access ramp using the standard slope formula. It helps determine if a ramp meets accessibility standards by calculating the ratio of vertical rise to horizontal run.

2. How Does the Calculator Work?

The calculator uses the slope formula:

Where:

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

Explanation: The slope represents the steepness of the ramp, calculated as the ratio of vertical rise to horizontal run.

3. Importance of Ramp Slope Calculation

Details: Proper ramp slope calculation is crucial for ensuring accessibility compliance, safety, and usability for people with mobility challenges. The standard 1:12 slope is commonly required for accessibility ramps.

4. Using the Calculator

Tips: Enter the vertical rise and horizontal run values. Both values must be positive numbers. The calculator will compute the slope ratio.

5. Frequently Asked Questions (FAQ)

Q1: What is the standard slope for accessibility ramps?
A: The standard slope for accessibility ramps is typically 1:12, meaning for every 1 unit of vertical rise, there should be 12 units of horizontal run.

Q2: Why is the 1:12 slope ratio important?
A: This ratio provides a gentle slope that is manageable for wheelchair users and people with mobility aids, ensuring safe and comfortable access.

Q3: Are there different slope requirements for different applications?
A: Yes, some applications may allow steeper slopes (like 1:8 or 1:10) for short rises, but 1:12 is the standard for public accessibility.

Q4: What are the consequences of an overly steep ramp?
A: Steep ramps can be dangerous, difficult to navigate, and may not comply with accessibility regulations, potentially causing safety hazards.

Q5: Should handrails be included with ramps?
A: Yes, handrails are typically required on both sides of ramps for safety and accessibility, especially for ramps with a rise greater than 6 inches.
