Special Issue Information

Dear Colleagues,

The present Special Issue aims to explore the development of prefabricated spatial network structure, including the development of novel assembly joints, structural system innovation, structural analysis, structural design and methods for the structure optimization. The purpose of this issue is to present the latest research results related to prefabricated spatial network structure. The thematic scope includes experimental research, numerical analysis and theoretical analysis of components and structures. Studies on methods for the parametric modeling, design and optimization method of prefabricated spatial network structure are also very welcome.

In this study, the design of a flexible cable–strut tensile structure was optimised according to the importance of elements to achieve high structural robustness. First, the importance coefficients of elements were determined by comparing their structural prefailure and postfailure strain energy. Moreover, the effects of the external load, the initial prestress, and the cross-sectional areas of elements on the importance coefficients were analysed. Second, a genetic algorithm was used to optimise element section design and minimise the maximum importance coefficient. Third, an optimised cable arrangement scheme was developed by adding an alternative load transfer path to the outer hoop cable with the highest importance coefficient. In this scheme, outer elements have a Levy-type arrangement rather than a Geiger-type arrangement so that a Geiger–Levy composite cable dome is formed. Finally, the cable arrangement and element section design for the aforementioned scheme were comprehensively optimised to reduce the maximum importance coefficient. The results of this study indicated that different elements had different importance coefficients, which exhibited different trends with changes in the external load, the initial prestress, and the cross-sectional areas of elements. Element section optimisation, cable arrangement optimisation, and the comprehensive optimisation reduced the maximum importance coefficient by 20.5%, 11.6%, and 27.7%, respectively, which indicated that these optimisation processes can effectively improve the robustness of cable–strut tensile structures.

In this paper, the mechanical properties of hollow precast utility tunnels are studied by experimental and numerical methods. Through full-scale experiments, the failure modes of ordinary and hollow utility tunnels are studied, and the failure stages of the structures are classified based on the bearing capacity and damage to the structures. The nonlinear finite element model is used to simulate the behavior of the structure, and the optimal design of the structure under load type and the hollow ratio are discussed based on the finite element method. The theoretical calculation method of the bearing capacity for hollow structures in each stage is proposed, and its application scope is discussed. The finite element analysis can effectively predict the mechanical properties of the structure, and the failure of the utility tunnel structure is dependent on the shear bearing capacity. Although hollow design advances the structural damage under point load, the hollow structure has significant advantages under uniform loads or reasonable hollow ratios. It is reasonable to calculate the cracking load considering moment distribution at section centroid and the failure load considering the combined action of flexural and shear stress, but the hollow ratio should be less than 16%. Under reasonable hollow ratio or load conditions, the hollow design has little effect on the bearing capacity of the structure and can reduce the weight, which has practical value for architecture and construction.
