Abstract: Digital form‐fitting – Cog connections for complex steel structures. This paper discusses the potentials of form‐fit connections in steel structures to generate ‘digital details' which are easily adapted to different boundary conditions and organize their manufacturing and assembly. In this paper, a grid shell for a 45 m span ETFE cushion dome and a large membrane façade that use digital detailing as a basic principle for all joints of the structure, will be discussed. The projects demonstrate how the inclusion of simple digital production processes in the detail design enable rational planning, manufacturing and assembly of complex structures. Next to the new challenge in understanding geometric relationships, material properties, and manufacturing techniques, computationally expensive analysis using Finite Volume Elements with nonlinear connection and material models is necessary to the engineering of such details.

Abstract: In Japan, the new steel‐glass architecture of railway stations observes usually not only the typical canons of aesthetics but often also – increasingly – the local habits, traditions and social features. Moreover, such architecture is understood to respect well the natural and built environment – forming friendly compositions, which respond fairly to the needs of contemporary Japanese people. Thus, that architecture becomes certain steel‐glass art of structures. In this paper, on the basis of several practical examples, such special steel‐glass art will be presented. [ABSTRACT FROM AUTHOR]
