Abstract
Bifurcation buckling behavior of polygonal-shaped, truss dome structures is studied with the aid of a group theoretic method. This study extends the previous research on simple regular-polygonal truss domes to those with greater number of degree of freedoms and with much more realistic configuration. Unlike the previous research, radial and rotational displacements of the domes are included here in describing their bifurcation modes, in addition to vertical displacements. The method has permitted one to obtain potential bifurcation modes of the domes and hierarchies of bifurcation paths under axisymmetric loadings without performing bifurcation tracing analyses. The applicability of group theoretic method to regular-polygonal domes has been fully assessed through this study.
