Whether you call them rafters, truss members or beams - the truss calculator essentially does the same thing. It calculates 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 long span structures such as truss bridge design and roof trusses.
The truss analysis is being performed by our FEA solver, which is also used in our Structural 3D program. 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.
More Information on Trusses
A truss is typically a triangular structure that is connected by pinned joints such that they mainly incur an axial force (see what is a truss). 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.
Do More With Structural 3D
There are some limitations on the above truss calculator that can be achieved through full structural analysis software. Get more results (such as bending moment and shear force diagrams), get more members and loading types (area loads, distributed loads and self weight) and model in 3D.
