1. What Are Frame Reactions?

Frame reactions are the forces exerted by supports to maintain equilibrium in a structural frame when external loads are applied. These reactions are crucial for structural stability and design.

2. How Does the Calculator Work?

The calculator uses the basic reaction equation:

Where:

• \( Force \) — Applied external force in newtons
• \( Supports \) — Number of supporting points

Explanation: This simple equation assumes equal distribution of force among all supports, which is valid for symmetrical loading conditions.

3. Importance of Reaction Calculations

Details: Accurate reaction calculations are essential for proper structural design, ensuring that supports can handle the applied loads without failure.

4. Using the Calculator

Tips: Enter the total force in newtons and the number of supports. Both values must be positive numbers (force > 0, supports ≥1).

5. Frequently Asked Questions (FAQ)

Q1: What if the loading isn't symmetrical?
A: For asymmetrical loading, more complex calculations considering moment equilibrium are needed.

Q2: How does this apply to real structures?
A: This is a simplified model - real structures often require more detailed analysis considering material properties and geometry.

Q3: What types of supports does this assume?
A: This calculation assumes simple supports that only provide vertical reactions.

Q4: Can this be used for dynamic loads?
A: No, this is for static analysis only. Dynamic loads require additional considerations.

Q5: What about horizontal forces?
A: This calculator only considers vertical reactions. Horizontal reactions require different calculations.
