| Abstract: | Taking the virtual case of boundary support s in engineering practice into account and employing scientifically and rationally the feature of geometric symmetry with the spatial network structure, the bound ary constraints of several spatial network structures is analyzed theoretically, and then, on the basis of this analysis, a mathematical model consistent with e ngineering reality is presented so that the computation with optimization progra m of spatial network structures can be simplified and its accuracy guaranteed. |
| Keywords: | spatial net work structures optimum design boundary supports constraint conditions displacement coordination stiffnes s equivalent |
