Radial Pressure Formula:
Definition: This calculator determines the normal radial pressure at the centerline of an arch dam based on thrust at the crown and other geometric parameters.
Purpose: It helps civil engineers analyze stress distribution in arch dams to ensure structural integrity.
The calculator uses the formula:
Where:
Details: Proper calculation ensures the dam can withstand water pressure and other forces without excessive deformation or failure.
Tips: Enter all required parameters. The tolerance field (default ±5%) helps determine acceptable pressure ranges for safety factors.
Q1: What is typical thrust at crown for arch dams?
A: Thrust varies greatly by design but typically ranges from 10,000 to 500,000 N depending on dam size.
Q2: How is the angle θ determined?
A: θ is the central angle of the arch segment, calculated from the dam's geometry and design specifications.
Q3: Why include a tolerance percentage?
A: Engineering designs often allow for small variations; the tolerance helps identify acceptable operational ranges.
Q4: What if my result is negative?
A: Negative values may indicate calculation errors or physically impossible input combinations.
Q5: How accurate is this calculation?
A: This provides a theoretical value; actual field measurements may vary due to material properties and environmental factors.
