This paper presents the concept of Truss-Z (TZ) – a skeletal system for pedestrian traffic which is composed of only two modules and allows the creation of complex three-dimensional self-supporting networks connecting any number of terminals in a given environment. TZ is intended as a universal, feasible and practical system for newly designed situations and most importantly, for retrofitting, especially where the use of heavy equipment is impossible or uneconomic.TZ allows automated creation of optimal spatial links where the only required inputs are the coordinates of the terminals and the geometry of the obstacles. As an example a six-terminal network created with a backtracking based algorithm is shown. An alternative method of aligning consecutive modules to a given 3D path is also presented.A preliminary static analysis of the TZ module is carried out – the topological qualities of rigidity and independence are demonstrated.
Highlight
► The problem of free-form vs modularity in architecture and engineering is discussed.
► The structural rigidity and independence of the TZ module are demonstrated.
► A robust backtracking algorithm for automated creation of TZ networks is presented.
► A number of TZ networks in various situations using different methods are presented..
