What is a Continuous Beam?

A continuous beam is a structural element that spans across more than two supports. Unlike a simply supported beam, which has only two supports at its ends, a continuous beam provides greater structural rigidity and reduces the maximum bending moment across the spans. This makes it a preferred choice in bridge engineering, multi-story building frames, and industrial warehouses where long-range structural integrity is vital.

Why Use Our Online Continuous Beam Calculator?

Calculating internal forces like shear force and bending moments for continuous beams is complex because they are statically indeterminate. Traditional methods like the Three Moment Equation or Moment Distribution Method can be time-consuming. Our Continuous Beam Calculator Online Free tool provides instant results for standard loading conditions, helping students and engineers verify their manual calculations quickly.

How to Use This Tool

1. Select the number of spans your beam has (currently supports up to 3 spans).
2. Input the length of each span in meters.
3. Enter the Uniformly Distributed Load (UDL) acting across the entire length of the beam.
4. Click "Calculate" to see the vertical reactions at each support and the approximate internal moments.

Frequently Asked Questions

What are the benefits of continuous beams over simple beams?

Continuous beams generally have smaller deflections and lower maximum bending moments compared to a series of independent simply supported beams of the same length. This allows for the use of shallower sections, saving material and cost.

Is this tool suitable for complex point loads?

This specific version is optimized for Uniformly Distributed Loads (UDL), which is the most common design scenario for gravity loads in floor slabs and rafters. For complex asymmetric point loads, structural analysis software like FEA is recommended.
