In this article, the rational constructive form of combined steel truss with a span 30 meters is received, 59% fewer elements than typical. Calculated regulation methods are offered stress-deformation state (SDS) trusses, which make it possible to increase their efficiency. Methods estimated SDS in trusses given: change stiffness rodsand creation eccentricities nodes connecting lattice upper be...

An adaptive truss structure with self-learning active vibration control system is developed. A fuzzy-neural network (FNN) controller with adaptive membership functions is presented. The experimental setup of a two-bay truss structure with active members is constructed, and the FNN controller is applied to vibration suppression of the truss. The controller first senses the output of the accelero...

A truss climbing robot has been extensively investigated because of its wide range of promising applications such as construction and inspection of truss structures. It is designed to have degrees of freedom to move in three-dimensional truss structures. Although many degrees of freedom allow the robot to reach various position and orientation, it causes complexity of design and control. In thi...

Metaheuristic algorithms are preferred by the many researchers to reach the reliability based design optimization (RBDO) of truss structures. The cross-sectional area of the elements of a truss is considered as design variables for the size optimization under frequency constraints. The design of dome truss structures are optimized based on reliability by a popular metaheuristic optimization tec...

This study is to analyse the dynamical instability (or the buckling) of a steel space truss using the accurate solutions obtained by the high-order Taylor series method. One is used to obtain numerical solutions for analysing instability, because it is difficult to find the analytic solution for a geometrical nonlinearity system. However, numerical solutions can yield incorrect analyses in the ...

the present study tackled the modeling of dynamic truss structure using a topological approach. This approach is based on the notion of topological collections and transformations by applying the MGS language (Modeling of General System). For this purpose the MGS language was presented and applied in the case of N bar truss structure. Then, results obtained by MGS language were compared to thos...
