1. What is a Parking Garage Ramp Calculator?

Definition: This calculator determines the run and length of a parking garage ramp based on the vertical rise and desired slope percentage.

Purpose: It helps architects, engineers, and construction professionals design properly sloped ramps for parking structures.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

• \( \text{rise} \) — Vertical height change (feet)
• \( \text{slope} \) — Gradient percentage (%)
• \( \text{run} \) — Horizontal distance (feet)
• \( L \) — Actual ramp length (feet)

Explanation: The run is calculated by dividing the rise by the slope ratio, then the actual ramp length is found using the Pythagorean theorem.

3. Importance of Proper Ramp Design

Details: Correct ramp dimensions ensure vehicle accessibility, safety, and compliance with building codes (typically 6.67% maximum slope for parking garages).

4. Using the Calculator

Tips: Enter the vertical rise in feet and desired slope percentage (default 6.67%). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What's the standard slope for parking garage ramps?
A: Typically 6.67% (1:15 slope) is the maximum recommended for parking garages.

Q2: How do I measure the rise?
A: Measure the vertical distance between the ramp's starting and ending points.

Q3: Why is the actual length different from the run?
A: The actual length accounts for both horizontal and vertical components of the ramp.

Q4: Can I use this for ADA ramps?
A: No, ADA ramps have different requirements (max 8.33% slope). Use a dedicated ADA ramp calculator.

Q5: How does slope percentage relate to ratio?
A: A 6.67% slope equals a 1:15 ratio (1 unit vertical to 15 units horizontal).
