Cable Stayed Bridge Hand Calculations
Cable stayed bridge hand calculations are crucial for designing and maintaining cable stayed bridges. These calculations ensure the bridge’s stability and safety under various loads and conditions.
How to Use This Calculator
- Enter the bridge’s length, height, and slope.
- Enter the load (in kN) you want to apply.
- Click “Calculate”.
Formula & Methodology
The calculation uses the following formula to determine the hand force (F):
F = (L * H * sin(S)) / (2 * cos(S)^2)
Where:
- L = Bridge Length
- H = Height
- S = Slope (in radians)

Interactive FAQ
What is the maximum slope angle for a cable stayed bridge?
The maximum slope angle is typically around 60 degrees.
How do I interpret the calculated hand force?
The calculated hand force is the force exerted by the cable on the bridge’s hand. It should be used to design and reinforce the bridge’s structure.
