ABSTRACT
To enhance the overall stability of the glulam reticulated shell, an innovative structural solution, the glulam suspendome, is introduced by integrating a cable-strut system. A destructive test utilizing 13 hydraulic jacks was carried out to assess the overall stability. This study primarily encompassed analyses of load-displacement curves for nodes, load-strain characteristics of structural members, load-cable force assessments of hoop cables, and an investigation into failure mode. The failure mode of the structure involved instability around the weak axis of the member near the mid-span node, along with member fracture. The structure sustained an ultimate load of 1094.21kN (84.17kN×13). Based on the parameter analysis of the finite element model (FEM) of more than 200 cases of glulam suspendome, the ultimate bearing capacity improvement coefficient (k) of the suspendome structure compared with single-layer reticulated shell was given. The experimental and numerical analysis on the mechanical properties of glulam suspendome serves as a dependable point of reference for the design of other glulam suspendome.
