Nonlinear form-finding of symmetric cable–strut structures using stiffness submatrices associated with full symmetry subspace

An efficient and nonlinear form-finding method is proposed for symmetric cable–strut structures with complex geometry or many nodes. Expressed in the symmetry-adapted coordinate system, the first block matrix of the symmetry-adapted tangent stiffness matrix is extracted using the full symmetry subsp...
