Rationalization of trusses generated via layout optimization
Numerical layout optimization provides a computationally efficient and generally applicable means of identifying the optimal arrangement of bars in a truss. When the plastic layout optimization formulation is used, a wide variety of problem types can be solved using linear programming. However, the solutions obtained are frequently quite complex, particularly when fine numerical discretizations...
متن کاملPractical Plastic Layout Optimization of Trusses Incorporating Stability Considerations
Frequently, the topologies generated using conventional discrete structural layout optimization methods may be shown to be in unstable equilibrium with the specified applied loading. Instability may occur due to the lack of lateral bracing at a node lying within a line of parallel compression members (or ‘chain’), or at the end of a compression member. In practice, this would typically lead eit...
متن کاملlayout and size optimization of trusses with natural frequency constraints using improved ray optimization algorithm
natural frequency is one of the parameters that represent useful information about the dynamic behavior of structures. controlling this parameter can decrease the probability of damage under dynamic loading. weight optimization on layout and sizing with frequency constraints is a well known problem because of its highly non-linear behavior. improved ray optimization (iro) algorithm is utilized ...
متن کاملOptimization of timber trusses considering joint flexibility
This paper presents the optimization of metal-plate-connected plane timber trusses with special emphasis on joint flexibility. The optimization is performed by the non-linear programming approach. Since various truss design parameters such as type of truss configuration, span/depth ratio, number and type of diagonal and vertical members and type of joint connections simultaneously affect each o...
متن کاملDesign Optimization Of N-shaped Roof Trusses
Design optimization of a class of plane trusses called the N-Shaped Truss (NST) is addressed. The parametric model of NST presented is intended for real-world application, avoiding simplifications of the design details that compromise the applicability. The model, which includes twenty-seven discrete variables concerning topology, configuration and sizing of the truss, presents a challenging op...
