Simply Supported Beam Calculator.
Find support reactions and the maximum moment for a simple beam with a centre load, an offset load or a uniform load.
Moment uses your force unit times your length unit. The beam is simply supported, with no continuity, deflection or code check. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
- Left reaction
- 5 force
- Right reaction
- 5 force
- Maximum moment
- 15 force × length
The beam is simply supported. A centre point load splits equally and peaks at load × span / 4. An offset point load uses the opposite segment over the span, and the peak moment is at the load. A uniform load is force per length: each reaction is half the total and the peak moment is w × span² / 8.
How to use Simply Supported Beam Calculator
Enter the span and the load. For an offset load, also enter its distance from the left support. A uniform load is force per length.
How it works
Find support reactions and the maximum moment for a simple beam with a centre load, an offset load or a uniform load. Moment uses your force unit times your length unit. The beam is simply supported, with no continuity, deflection or code check. Local arithmetic only. This is a quantity or geometry estimate, not a code check and not a substitute for a licensed professional.
Example
A 6 m span with a 10-unit point load at midspan.
