Calculation of Buckling Load and Eigen Frequencies for Planar Truss Structures with Multi-Symmetry
In this paper, the region in which the structural system is situated is divided into four subregions, namely upper, lower, left and right subregions. The stiffness matrix of the entire system is then formed and using the existing direct symmetry and reverse symmetry, the relationships between the entries of the matrix are established. Examples are included to illustrate the steps of the method.
متن کاملPlanning the reconfiguration of grounded truss structures with truss climbing robots that carry truss elements Citation
In this paper we describe an optimal reconfiguration planning algorithm that morphs a grounded truss structure of known geometry into a new geometry. The plan consists of a sequence of paths to move truss elements to their new locations that generate the new truss geometry. The trusses are grounded and remain connected at all time. Intuitively, the algorithm grows gradually the new truss struct...
متن کاملShape morphing hinged truss structures
Truss structures are widely used for the support of structural loads in applications where minimum mass solutions are required. Their nodes are normally constructed to resist rotation to maximize their stiffness under load. A multi-link node concept has recently been proposed that permits independent rotation of tetrahedral trusses linked by such a joint. High authority shape morphing truss str...

متن کاملFuzzy Optimum Design of Plane Truss Structures
The main objective of structural engineers through out design history has been to obtain the optimum structure under the prescribed design conditions which can not only withstand external loads safely but also achieve an economic solution. The paper focuses on the use of the fuzzy set theory to optimum design of plane truss structures. The approach is illustrated on planar truss optimization pr...
