The paper describes and demonstrates an optimization tool that combines methods developed independently in the fields of structural engineering and fine art. Optimization has a long history in structural engineering. Most commonly, structural optimization seeks a configuration that minimizes material volume, subject to constraints on strength and stiffness. Metaheuristic search methods, such as...

This poster paper summarizes ongoing dissertation research (under the direction of Dr. Christopher M. Foley) concerned with the utilization of genetic algorithms for the optimization of steel structures that have semi-rigid connections using advanced inelastic analysis and performance based engineering design. An evolutionary algorithm has been developed that extends the standard genetic algori...

In this paper, multi-objective optimization of railway wheel web profile using bidirectional evolutionary structural optimization (BESO) algorithm is investigated. Using a finite element software, static analysis of the wheel based on a standard load case, and its modal analysis for finding the fundamental natural frequency is performed. The von Mises stress and critical frequency as the proble...

Structural optimization, when approached by conventional (gradient based) minimization algorithms presents several difficulties, mainly related to computational aspects for the huge number of nonlinear analyses required, that regard both Objective Functions (OFs) and Constraints. Moreover, from the early '80s to today's, Evolutionary Algorithms have been successfully developed and applied as a ...

This paper presents initial results of a study on the application of evolutionary multiobjective optimization methods in the design of the steel structural systems of tall buildings. In the paper, a brief overview of the state-of-the-art in evolutionary multi-objective optimization in structural engineering is provided. Next, conceptual design of steel structural systems in tall buildings is ov...

Abstract Buckling is a critical phenomenon in structural members under compression, which could cause catastrophic failure of structure. To increase the buckling resistance design, novel topology optimization approach based on bi-directional evolutionary (BESO) method proposed this study with consideration constraints. The BESO benefits from using only two discrete statuses (solid and void) for...

Monitoring and surveillance of buildings, especially in critical infrastructure is crucial to increase the lifetime such structures. This due fact, that concrete like bridges or road tunnels are prone corrosion their exposure elements. For this task, wireless sensor nodes can be employed structural health monitoring. In last few years passive RFID sensors have been proposed gather data from ins...
