“…With the development of the economy and the continuous progress of society, the increasing demands for public entertainment venues have necessitated the emergence of large-span space structures [1]. Among these structures, the network and shell structure [2][3][4][5] has gained widespread application due to its numerous advantages, including its aesthetically pleasing design, uniform stress distribution, lightweight construction, high stiffness, and expansive coverage space.…”

The net shell is a widely utilized large-span space structure known for its aesthetically pleasing design and uniform load distribution, as well as serving as a prominent architectural landmark. In recent years, the impact resistance research of mesh and shell structures has garnered increased attention due to the accumulation of local conflicts. In this study, a parametric model of the spherical mesh shell was developed with Rhino software, and a numerical analysis model for a K8 mesh shell was established through the application of the ABAQUS finite element analysis software. Subsequently, the proposed numerical analysis method for the impact test was applied to validate its accuracy. The research also explored various dynamic constitutive models, such as Cowper-Symonds, Johnson-Cook, modified temperature term Johnson-Cook, and modified strain term and temperature term Johnson-Cook, with the assessment of their impact on the numerical simulation of impact resistance. Based on the impact dynamic response of the spherical net shell of different materials, the selection of an appropriate dynamic constitutive model for the numerical simulation of impact resistance in the spherical net shell was the MJ-C model. The comparative analysis of different materials, including Q235B, Q355B, Q460D, and 6061-T6, indicated that when the impact material failed to penetrate the structure instantly, the improvement of the material strength would enhance the impact resistance of the structure. On the other hand, when the impact material managed to penetrate the structure instantly, the material strength would not significantly help mitigate the damage. Notably, brittle materials, such as aluminum alloy, exhibited a distinct absence of a pronounced yield stage compared with low-carbon steel, which ultimately led to a relatively abrupt deformation.

“…With the development and progress of science and technology, people's production and living activities put forward higher requirements on the space, structure and function of buildings. The large-span spatial grid structure has the advantages of beautiful shape, superior mechanical properties, and large spatial span, making it being widely used in large public buildings such as terminals, large stadiums and theaters [1][2]. Public buildings tend to have heavy traffic and carry some important economic and social functions in the city, therefore the safety of public buildings should not be neglected.…”

The progressive collapse of the spatial grid structure is the focus and difficulty of the current research. The stability problem of the single-layer latticed shell structure is more prominent due to its low redundancy. In this paper, the dynamic nonlinear analysis of the Zhoukoudian large-span single-layer latticed shell structure is carried out to study its progressive collapse process by the finite element software ABAQUS. The results show that the structure eventually collapse under 7 times the gravity load. The mid-span zone on the left side of the structure is the weak point of the structure where the earliest failure members appear. After the failure members appear for the first time in the structure, the vertical displacement increases faster, and then the failure members develop along the longitudinal and transverse directions of the structure starting from the mid-span zone on the left side, which eventually leads to the failure of the structure.
