Roof Truss Calculator / Joist Calculator
About the Roof Truss Calculator
This free online roof truss calculator is a truss design tool that generates the axial forces, reactions of completely customizable 2D truss structures. It has a wide range of applications including being used as a wood truss calculator, roof truss calculator, floor joist calculator, scissor truss calculator or roof framing. Trusses are typically modelled in triangular shapes built up of diagonal members, vertical members and horizontal members.
How to use this Roof Truss Calculator?
Simply add nodes, members and supports to set up your model, apply up to 5-point loads (distributed loads can be added in full version), then click solve to run the static 2D truss analysis. It is particularly useful as a steel bridge truss design software or roof truss calculator. Click 'Reactions' or 'Axial Force' to display your results in a nice, clean and easy-to-interpret graph for your truss design. Users can also control settings such as units, display settings of truss members etc. by clicking the 'Settings' button.

More Information on Trusses and Truss Calculator
A truss is typically a triangular structure that is connected by pinned joints such that they mainly incur an axial force. This above tool will allow you to run truss analysis on any of these trusses to get the internal member forces. There are a number of different types of trusses, including pratt truss, warren truss and howe truss; each with their own set of pros and cons.
Truss Calculator
Enhance your workflow with our versatile truss calculator. Whether you are looking for a wood truss calculator, roof truss calculator, floor joist calculator, scissor truss calculator, attic truss calculator, or for roof framing, our tool has you covered..By upgrading to one of SkyCiv's pricing options, you can unlock our truss analysis calculator, allowing you to select materials such as wood and steel to perform truss design and analysis - making it much more than a simple roof calculator.
Whether you call them joist, truss members, or roof trusses, our truss calculator performs the same essential function: calculating the internal axial forces in these members. The internal forces are important as they are commonly the governing force to look for in truss structures. Such structures are frequently used in truss long-span structures such as truss bridge design and roof trusses.
Truss Solver
Our FEA solver performs the truss analysis, delivering accurate results for your projects. The calculations made are based on splitting the member into 10 smaller elements and calculating the internal forces based on these. The truss solver can handle extremely large structures of more than 10,000 members. So if you have a larger structure, simply upgrade and you can use the full S3D program for all your analysis needs.
Do More With Structural 3D
There are some limitations on the above truss calculator that can be achieved through SkyCiv Structural 3D. With the truss analysis calculator integrated into the software, you can access more advanced features such as bending moment and shear force diagrams, handle more members and loading types (area loads, distributed loads and self weight) and model in 3D. SkyCiv is built to make steel truss design easier for you, with a range of powerful analysis and modelling capabilities.
