“…Characterized by large spans, structural stability, cost-effective material use, and aesthetic qualities, this field has seen significant contributions from numerous researchers across various studies on latticed shell structures. Focusing on the issues of stability and collapse, several scholars have developed methodologies for calculating the distribution of internal forces and failure loads [1][2][3][4][5][6], along with collapse analysis techniques [7], by employing finite element analysis and considering both the unique properties of these structures and the nature of the applied loads. On this basis, Zhang et al [8] proceeded to calculate the dynamic failure loads of latticed shell structures by adhering to relevant standards and employing fitted calculation formulas.…”

The cable-stiffened single-layer latticed shell is an innovative structural design that achieves a perfect balance between lightweight and stability by combining cables and a latticed shell. However, the study on dynamic response and failure mechanism of cable-stiffened single-layer latticed shell under seismic action is still lacking. Therefore, small-scale shaking table tests of two kinds of single-layer spherical latticed shells are carried out; the dynamic response and failure mode of the two shells under sine wave earthquake are investigated by using time history analysis. The conclusions show that the introduction of the prestressed cable plays an important role in improving the seismic performance of the single-layer latticed shell, and the cable-stiffened single-layer latticed shell has better load capacity and seismic performance under earthquake action than the ordinary single-layer latticed shell structure.
