Abstract

Abstract

Carbon fiber reinforced polymer （CFRP） composites， owing to their exceptional material properties， offer a novel solution for cable components in long-span spatial structures. Therefore， a CFRP spoke-type tensegrity structure was implemented in the roof system of an airport， utilizing CFRP cables as the primary load-bearing elements. To better understand the structural responses during different construction stages， cable tensioning schemes were developed based on structural characteristics. A full-process simulation of CFRP cable tensioning was conducted using an improved tension compensation method， presenting key response parameters such as cable forces， structural deformations， and internal forces at each construction step. The numerical simulation of the entire tensioning process validated the rationality of the structural design and the feasibility of the construction procedure， thereby providing a theoretical foundation for the actual construction implementation.
