ABSTRACT
According to the existing experimental results, the roofing systems considerably influence the bearing capacity and plastic development of reticulated shell substructure models; however, the mechanism of this influence of the roofing system on the static stability of reticulated shell structures remains unclear. In this paper, based on experimental studies, the finite element model of reticulated shell structures with different roofing systems are established, and the influence of various factors of the reticulated shell structures (rise span ratio, roof load, initial imperfection amplitude and mode) and roofing system (pillar and purlin joint) are analysed. Furthermore, the influence ranges of the roofing system on the static bearing capacity of the shells are recommended.
