What is a Truss?

A truss is a structure that consists of a collection of elements connected at pin joints or nodes. In theory, the pin joints provide no rotational resistance and behave as hinges. In practice this is not always the case.

In this tutorial, weโ€™ll discuss common forms of truss, their features, approximate methods of analysis and the key assumptions that relate to our analysis.
