Multiobjective optimization of planar truss girder

Multiobjective Design Optimization of 3–PRR Planar Parallel Manipulators

This paper addresses the dimensional synthesis of parallel kinematics machines. A multiobjective optimization problem is proposed in order to determine optimum structural and geometric parameters of parallel manipulators. The proposed approach is applied to the optimum design of a three-degree-of-freedom planar parallel manipulator in order to minimize the mass of the mechanism in motion and to...

Multiobjective dynamic topology optimization of truss with interval parameters based on interval possibility degree

Static and dynamic multiobjective topology optimization of trusses with interval parameters is investigated. The uncertain parameters of the trusses are described by an interval model. The multiobjective topology optimization model of trusses with interval parameters is constructed. On the basis of Taylor expansion and natural interval extension, the stress and displacement response intervals u...

Multiobjective Optimization of Truss Topology by Linear/Sequential Linear Programming Method

The present paper deals with a multiobjective optimization of truss topology by either Sequential Linear Programming (SLP) method or Linear Programming (LP) method. The ground structure approach is often used to solve this kind of design problems. In this paper, the topology optimization is formulated as a Multiobjective Optimization Problem (MOP), which is to find the cross-sectional area of t...

Experimental and Numerical Investigation on Bending Capacity of Steel- concrete Composite Truss Girder

This article presents an experimental investigation on the bending capacity of steel-concrete composite truss girder (SCCTG). Four full-scale specimens named CB1, CB2a, CB2b and CB3 respectively, are tested and numerical analyzed. Stress distribution, load-displacement relationship, load-slip relationship and ultimate bending capacity of SCCTGs are investigated. The results show that SCCTG foll...
