Slope Formula:
From: | To: |
Definition: This calculator determines the slope percentage of a parking ramp based on its vertical rise and horizontal run.
Purpose: It helps architects, engineers, and construction professionals design parking ramps with proper slope gradients (typically 5-20%).
The calculator uses the formula:
Where:
Explanation: The rise is divided by the run to get the slope ratio, then multiplied by 100 to convert it to a percentage.
Details: Correct slope ensures vehicle accessibility, safety, and compliance with building codes while preventing drainage issues.
Tips: Enter the vertical rise and horizontal run in feet. Both values must be > 0. The result shows slope as a percentage.
Q1: What's the typical slope range for parking ramps?
A: Most parking ramps have slopes between 5% (minimum) and 20% (maximum), with 15% being common.
Q2: How does slope affect parking ramp design?
A: Steeper slopes require more careful design of transitions, drainage, and safety features.
Q3: What's the difference between rise and run?
A: Rise is the vertical change in height, while run is the horizontal distance covered.
Q4: How do I measure rise and run in an existing ramp?
A: Use a level and tape measure for run, and measure height difference for rise.
Q5: Are there regulations for maximum slope?
A: Yes, local building codes typically specify maximum allowable slopes for accessibility and safety.
