3. Introduction In structural and mechanical design, deterministic design optimization models have been successfully developed. Recently, the robust structural design has received increasing attention. Based on stochastic uncertainty models of mechanical parameters, various techniques were proposed for evaluation and estimation of failure probabilities [7, 11], that can be utilized in the relia...

In this article, a new method of increasing the efficiency combined steel roof trusses is proposed and considered. A rational shape truss, including its topology geometric parameters, was obtained, but without obtaining SSS. provides adjustment SSS in truss by changing upper belt panel length. On basis obtained structural form proposed. It shown that thanks to method, it possible obtain more ef...

A robust truss optimization scheme, as well as an optimization algorithm, is presented based on the robustness function. Under the uncertainties of external forces based on the info-gap model, the maximization problem of robustness function is formulated as the optimization problem with infinitely many constraint conditions. By using a semidefinite relaxation technique, we reformulate the prese...

We discuss the use of homogenization techniques to derive approximate models with simple geometry for physical models of grids and trusses which have a complex geometry that gives rise to computational diiculties. Our presentation is in the context of inverse or parameter estimation problems for composite material structures with unknown characteristics such as stiiness and internal damping. We...

One of the primary objectives truss structure design optimization is to minimize total weight by determining optimal sizes members while ensuring structural stability and integrity against external loads. Trusses consist pin joints connected straight members, analogous vertices edges in a mathematical graph. This characteristic motivates idea representing as graph edges. In this study, Graph Ne...
