Best Websites for Drawing Shear Force and Bending Moment Diagrams Online for Free

Performing structural analysis does not require expensive software. There are several online tools available that allow you to draw shear force and bending moment diagrams for your projects for free. Here are some highly rated and reliable options:

1. SkyCiv

Website: SkyCiv Beam Calculator

SkyCiv is a popular choice for its user-friendly interface and powerful built-in tools. You can input your beam information, and it will generate the diagrams automatically. This makes it an excellent option for quick and accurate analysis.

2. BeamCalc

Website: BeamCalc

BeamCalc is another reliable tool that helps you create shear and moment diagrams by entering the beam's load conditions. The interface is straightforward, making it easy to use for both beginners and experienced engineers.

3. Wolfram Alpha

Website: Wolfram Alpha

While not specifically designed for this purpose, Wolfram Alpha can solve for shear and moment diagrams by entering specific equations or load conditions. It's a powerful computational engine and a great tool when you need to solve complex equations.

4. MyEngineeringLab

Website: MyEngineeringLab

This site provides a free tool for generating shear and moment diagrams based on user input. It's simple to use and can be a valuable resource for quick analysis and problem-solving.

Recommended Tool: StructureCalcs

Website: StructureCalcs

One of the most helpful tools I've found is StructureCalcs. This user-friendly tool not only calculates support reactions, shear force, bending moment, and deflection for different load cases and supports but also allows you to include support settlement and vertical displacement. It can solve for multi-beam properties, such as different modulus of elasticity and/or different second moments of area, making it an ideal choice for most mechanics/structure questions.

User-friendly Interface and Features

StructureCalcs can not only draw shear and bending moment diagrams but also calculate all reactions in an indeterminate or determinate structure. Its user-friendly interface ensures a smooth and efficient workflow, making it a valuable tool for students and professionals alike.

Additional Tools for Engineering Analysis

In addition to StructureCalcs, you may also consider other tools like,
