Robust Solutions of Optimization Problems Affected by Uncertain Probabilities [PDF]
In this paper we focus on robust linear optimization problems with uncertainty regions defined by ø-divergences (for example, chi-squared, Hellinger, Kullback-Leibler).

Explicit FE Modelling of Cold‐formed Steel K‐Joints using Dimpled Screwed Connections
Abstract Cold‐formed steel (CFS) thin‐walled structures, such as floor joists, are becoming popular in mid‐rise buildings. These joists are typically fabricated as truss systems, with unlipped channels forming the top and bottom chords and lipped stiffened channels used as diagonal web members.

It is still a challenge to evaluate the benefits of the morphing wing concept with a truss-braced wing wing–body–tail configuration. To address this problem, first, a fair baseline configuration is obtained with a multipoint optimization over six flight ...

Simultaneous Topology, Shape and Size Optimisation of 2D Trusses with Practical Constraints
Abstract This study introduces a novel optimisation methodology for 2D trusses, based on genetic algorithms. It combines topology, shape and size optimisation into a single procedure, while bridging the gap to practical application. This is achieved by including Eurocode EN 1993‐1‐1 deflection and capacity checks, using discrete section sizes from a ...

Practical Truss Layout Optimisation with Connection Penalisation
Abstract This study introduces a layout optimisation framework for minimum volume truss structures that explicitly accounts for connection complexity. Conventional minimum volume formulations identify material‐efficient layouts but often yield designs with excessive nodal connectivity and many lightly loaded members, making them impractical and costly ...

ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

The stiffness spreading method for layout optimization of truss structures
A novel optimization method, stiffness spreading method (SSM), is proposed for layout optimization of truss structures. In this method, stiffness matrices of the bar elements in a truss structure are represented by a set of equivalent stiffness matrices ...
