What is Single Beam Calc?
Single Beam Calc is a structural calculation app that combines beam calculations, buckling calculations, and natural frequency calculations in one app.
Simply enter the required conditions on your smartphone and quickly check the calculation results.
In addition to calculating shear force, bending moment, deflection, and stress for beams, the app also supports column buckling calculations and natural frequency calculations.
It is useful for preliminary structural design, quick checks in the field, and learning structural mechanics when you need to perform a calculation quickly.

Key Features
Single Beam Calc provides three main calculation tools:
- Beam Calculator
- Buckling Calculator
- Natural Frequency Calculator
You can also save and share calculation results as reports.
1. Beam Calculator
This is the core feature of Single Beam Calc.
The beam calculation function is designed specifically for single beams, allowing you to combine various support conditions and load conditions.




Support Conditions
The following boundary conditions can be used to define a beam:
- Free end
- Simple support
- Fixed end
Load Conditions
The following load types can be combined:
- Point load
- Uniformly distributed load
- Triangular distributed load
- Moment load
Up to five load conditions can be added, allowing you to calculate beams subjected to multiple loads.
Calculation Results
Calculation results can be displayed not only as numerical values but also as graphs.
- Deflection
- Support reactions
- Bending moment
- Shear force
- Bending stress
- Shear stress
- von Mises stress
Material properties can also be entered to calculate stresses and other results.
2. Buckling Calculator
The buckling calculation feature allows you to perform buckling checks for columns and other compression members.
Enter conditions such as member length, section properties, material properties, and support conditions to perform the buckling calculation.
The buckling calculation can be used to check the load at which a compression member may buckle.
It can be useful for preliminary structural design as well as for learning about structural buckling.
Buckling Calculation Results
The app provides calculation results related to buckling, including:
- Buckling load
- Buckling-related calculation results
- Results based on the entered conditions
Available calculation methods, input parameters, and displayed results may vary depending on the app version.

3. Natural Frequency Calculator
Single Beam Calc can calculate the natural frequency of beams and other structural systems.
Every structure has natural frequencies at which it tends to vibrate.
Single Beam Calc calculates natural frequencies based on the entered structural conditions, allowing you to check the vibration characteristics of a structure.
Natural Frequency Calculation
Natural frequency calculations can be useful for:
- Checking vibration characteristics
- Learning structural mechanics
- Preliminary structural studies
- Basic design checks

Save Calculation Results as Reports
Calculation results can be saved as report images.
Instead of simply checking the results on screen, you can save them for later reference or share them with others.
Saved reports can be useful for:
- Design notes
- Recording calculation results
- Internal information sharing
- Meetings
- Field checks
- Study records
Once saved to your smartphone, the calculation results can be reviewed whenever needed.
Save Calculation Conditions
Calculation conditions can also be saved, reducing the need to enter the same information again.
This is useful when you want to modify individual conditions and compare different calculation cases.
Structural Calculations on Your Smartphone
Structural calculations sometimes require starting a PC or creating calculation formulas in a spreadsheet, even when you only want to perform a quick check.
Single Beam Calc is designed as a practical calculation tool for those moments when you want to check a result immediately.
Keep the app on your smartphone and perform calculations whenever you need them.
Who is Single Beam Calc For?
Structural, Architectural, and Civil Engineers
Useful for quickly checking beam stresses and deflections, column buckling, natural frequencies, and other structural calculation results.
Engineers Who Need Quick Field Calculations
Check calculation results from your smartphone even when you are away from your PC.
Students Learning Structural Mechanics
Try practical calculations involving beam bending, shear, deflection, buckling, and natural frequency.
Anyone Who Needs a Quick Structural Calculation
Useful for simple preliminary checks when a full-scale structural analysis program is unnecessary.
