Beam Fixed at Both Ends Under Uniform Load — Shear & Moment Diagram
This tool illustrates the behaviour of a beam fixed at both ends under a uniformly distributed load. A fixed–fixed beam develops significantly lower midspan moments and deflections compared to a simply supported beam, making this configuration ideal for situations where stiffness is critical.
The diagram shows end moments, reaction forces, shear distribution, and the bending moment curve, along with the governing equations used in structural engineering practice. This model assumes fully fixed supports, linear-elastic behaviour, and a constant flexural stiffness along the span.
Engineers commonly reference this case when designing:
- concrete slabs supported by stiff walls or cores
- continuous steel or wood beams
- balcony slabs
- industrial platforms
- beams within rigid frames
This makes it a valuable quick-reference tool for estimating capacities, stiffness, and load distribution.
Using These Values in a Real Project?
If you're using these values for:
- Structural design
- Load calculations
- Load bearing wall removal
These values should be verified within the context of your actual structure and site conditions.
We provide stamped structural assessments and calculations across Ontario, based on real conditions, not assumptions.
Assessments consider site conditions, structural configuration, and applicable design requirements specific to your project.
