Optimization on Geometry Design of Double-Layer Space Trusses
Double-layer space truss (DLST) is widely known by the square-on-square configuration system. This study is conducted to find the optimum design between the other configuration such as diagonal-on-square (DOS), square-on-diagonal (SOD), and triangle-on-triangle (TOT). As designers need to be competitive in the industry, they need to come out with creative design using minimal materials while achieving adequate strength. Thus, they need to have guidelines to use other geometry configuration. Optimum design in this study includes section size diameter, minimal materials consumption with adequate strength. Structural analysis software, SAP2000, is used in finding the optimum section diameter by optimization techniques. Then, stress capacity check will be conducted to understand the behaviour of each member. DLST is commonly subjected to progressive collapse cause of failure of buckling member. Thus, it is crucial to understand the behaviour and the vulnerability of the structure. To achieve optimum design, strength to weight ratio comparison of DLST is done to find the most lightweight structure with adequate strength. Comparison between all the DLSTs is made and DOS is the most optimum design based on section size, minimal materials and adequate in strength. However, DOS have the highest DCR value member and the most vulnerable among all DLSTs. Thus, DOS is more suitable to be used for light loads and moderate span structure and is proved to be economic. TOT is the least optimum in section size diameter and the least vulnerable among all DLSTs. This indicates that the optimization technique will assist designers to design new configuration forms instead of the conventional system.
