ST7-220.127.116.11 Using String Groups
The Beam String Group attribute is used to model a continuous chain of truss type beam elements sliding through frictionless connections at nodes. The attribute ensures that a constant axial force develops in all the elements in the same string group. A common application of the attribute is to model massless cables (or strings) such as pulley systems, lifting sling cables, and pre-stressed steel tendons in reinforced concrete. This Webnote examines the Beam String Group attribute and its modelling applications.
