Dynamic strut-and-tie models - a graphical method to analyse dynamic processes using the exemple of an arc with a tension cable

摘要

The idea to analyse processes of movement by means of dynamic strut-and-tie models is based on the vectorial force flow analysis of static problems but expands its application to complete dynamic processes. A strut-and-tie model is a vectorial analysis of layouts and polygons of forces carried out graphically for each knot of a system. If the layout of the polygon of forces is closed, the knot analysed is in static equilibrium. If the polygon of forces is not closed, the knot will be accelerated by the resulting force depending on its mass.
