This model represents a part of the continuous structure of a tubular rail. The general geometry was created with parameterization. Uniform and alternating field loads and temperature are provided as load examples. Furthermore, various steel connections have been implemented as examples (a round tube column base with stiffeners, a round tube flange with stiffeners, a round tube connection from a larger to a smaller diameter, a round tube flange with unsymmetric stiffeners, an unsymmetric tube flange, welded connections of hollow sections).
