Optimization of steel truss bridge
Asian Journal Of Multidimensional Research, 2023This thesis aims to optimize the weight for double lane steel truss bridge with RCC composite deck of 100m span. The optimization here is targeted to achieve minimum weight of the steel and relationship between weight of steel and truss height, weight of truss and height to span ratio, wind force and truss height to span ratio.

An Improved Particle Swarm Optimizer for Truss Structure Optimization
2006 International Conference on Computational Intelligence and Security, 2006This paper presents an improved particle swarm optimizer (IPSO) for solving truss structure optimization problems. The algorithm is based on the particle swarm optimizer with passive congregation (PSOPC) and a harmony search (HS) scheme. It handles the problem-specified constraints using a `fly-back mechanism' method and the variables' constraints ...

Truss Optimization In Aerospace Structures
SAE Technical Paper Series, 2001<div class="htmlview paragraph">This work presents an approach for the structural optimization of 2D and 3D aerospace truss structures. The main goal is to reduce the volume (or weight) of the structure while satisfying constraints such as compliance, member stresses, local or global buckling, for one or more load cases.

Optimal Truss Design by Interior-Point Methods
SIAM Journal on Optimization, 1998Summary: This article presents a primal-dual predictor-corrector interior-point method for solving quadratically constrained convex optimization problems that arise from truss design problems. We investigate certain special features of the problem, discuss fundamental differences of interior-point methods for linearly and nonlinearly constrained ...

A New Method for Optimal Truss Topology Design
SIAM Journal on Optimization, 1993Summary: Truss topology optimization formulated in terms of displacements and bar volumes results in a large, nonconvex optimization problem. For the case of maximization of stiffness for a prescribed volume, this paper presents a new equivalent, an unconstrained and convex minimization problem in displacements only, where the function to be minimized ...

ON TOPOLOGY OPTIMIZATION OF TRUSSES
Engineering Optimization, 1985The selection of a minimum weight truss, out of a large set of candidate trusses, is treated. An initial configuration is generated by connecting all the n nodal points with n(n − 1)\2 truss members. A feasible displacement field, satisfying displacement and stress constraints, is obtained from a static analysis of this truss, followed by a uniform ...

Efficient optimization of space trusses
Computers & Structures, 1986An efficient and robust algorithm is developed for minimum weight design of space trusses with fixed geometry employing the general geometric programming (GGP) technique. The nonlinear programming (NLP) problem is formulated based on the virtual work method of structural analysis.

1985
We consider a truss of given layout that is subject to a single set of loads. The bars of the truss are to consist of a given, rigid, perfectly plastic material with tensile and compressive yield stresses ±σ0. The truss is to have a given load factor for plastic collapse under the given type of loading, while the total volume of its prismatic bars is ...

Multicriteria Truss Optimization
1988The origin of structural optimization can be traced back several centuries (Ref. 1), but it is only during the last two decades or so, with the advent of modern computers, that it has evolved into a mature discipline in engineering. The literature published in this field is extensive and it can be reasonably discussed here only by referring to some ...
