Parameters rationalization for flat double-layer grid spatial structure (STiSK system)

Abstract

It is the initial paper in rationalization of steel consumption for flat double-layer grid spatial structure of STiSK system. Brief historical review of metal spatial structures was given. Main economic and production advantages of the system were described Optimal geometry parameters that are satisfied to both ultimate limit and service ability states are offered. Some vital aspects related to the structure BIM design are clarified as well. Results of this research can be used by design engineers, as a basis for geometry determination of STiSk system. Outcomes of the paper can helpful for manufacturers of metal structures as well, and can help them to build up smart life-cycle designs (from engineer's idea to maintenance). BIM process that was presented in this paper will enhance rationalization process of STISK system and opens way for new designs based on this structure. The process can serve as a theoretical basis for full scale tests.
