Abstract: The analysis procedure of cable-strut structure in point-supported curtain walls has its special characteristics In allusion to it, the finite element analysis (FEA) basic flow of cable-strut structure of point-supported curtain walls was introduced, and a four-layer system structure including interface layer, control layer, the FEA layer and data layer was proposed, as well as the function structure. A global FEA solution using initial state analysis with twice singular value decomposition combined with load-up condition analysis with CR formation method was proposed. Finally, a finite element analysis system for cable-strut structure of point-supported curtain walls was developed, and the example indicated that the calculated results of the system were precise and valid.
Key words: mechanical manufacturing and automation; cable-strut structure; finite element analysis; four-layer system structure; initial state analysis; load-up condition analysis
