## What is A?

The Space Frame is considered to be the complicated structure due to  the members of such frames may be oriented in any directions in three-dimensional space more over the external loads oriented in any arbitrary directions can be applied to joints, as well as members. 

A-Frame 3D is an app that is so easy to use yet so powerful!!! 

Data input is just as simple as
- Node coordination (x, y, z)
- Member alignment (node-i  to node-j)
- Applied loads to each nodes and members
- Material properties E, G, Iy, Ix, J and A values

Not only A-Frame can solve the Space Frame but the app also showing the calculation step by step for the result data so that you can counter check the correctness of the calculation.

A-Frame 3D is an application for structural engineers or engineering students who need a tool to analyze the space frames.

A-Frame 3D solves the space frame by using the Stiffness Matrix Method, providing following features:

- The frame members can be aligned in any direction in space.
- Load applied to each members can oriented in any direct around the frame members.
- Equilibrium check for Forces & Bending Moments
- Deformation of each points along the members.
- Shear Force Diagram (S.F.D) and Bending Moment Diagram (B.M.D) of each sections along each members in 3D.

## Key features

- 3D space frame analysis
- Stiffness Matrix Method
- Step-by-step calculation display
- Equilibrium check
- Deformation visualization
- Shear Force & Bending Moment Diagrams


## Frequently asked questions about A

### What is A-Frame 3D used for?

A-Frame 3D is an application designed for structural engineers and engineering students to analyze complex 3D space frames. It allows users to input structural data and receive detailed analysis results.

### How does A-Frame 3D analyze space frames?

The application utilizes the Stiffness Matrix Method to solve space frames. This method is capable of handling members oriented in any direction and loads applied in arbitrary directions.

### Can I see how A-Frame 3D arrives at its results?

Yes, A-Frame 3D shows the calculation step by step for all result data. This feature allows users to counter-check the correctness of the calculations performed by the app.

### What kind of diagrams does A-Frame 3D provide?

A-Frame 3D provides Shear Force Diagrams (S.F.D) and Bending Moment Diagrams (B.M.D) for each section along each member in 3D. It also shows the deformation of each point along the members.

### What input data is required for A-Frame 3D?

To use A-Frame 3D, you need to input node coordinates (x, y, z), member alignment (node-i to node-j), applied loads to nodes and members, and material properties (E, G, Iy, Ix, J, and A values).

### What devices does A-Frame 3D support?

A-Frame 3D currently supports iPad devices. It is not available on other platforms like iPhone or Android at this time.

### How often is A-Frame 3D updated?

The latest version of A-Frame 3D is 3.0, which was last updated on May 11, 2025. This indicates a recent update, suggesting ongoing development and support.

### Does A-Frame 3D have ads?

No, A-Frame 3D does not contain advertisements. As a paid application, users can expect an ad-free experience.
