Structural Optimization for Materially Informed Design to Robotic Production Processes

Structural Optimization for Seismic Design

The application of Heuristic Search Methods for the earthquake resistant design of structural frames is discussed. The Tabu Search method was selected for application to structural weight optimization of steel moment frame structures. A computer program was developed that uses Tabu Search for weight minimization of two-dimensional framed structures. Written in the FORTRAN computer language, the...

Multimodal structural optimization for conceptual design

The paper describes an optimization method to support the conceptual stages of structural design. The method, called Blended Close Harmony Search, is a population-based metaheuristic approach that incorporates the following key features: 1) decision variable types that include real numbers defining geometry, discrete structural sections, and topology variables of enumeration (e.g. how many bays...

Solid Free Form Design for Structural Optimization

Most of the work in the field of topology optimization is concentrated on using sensitivity analysis and optimality criteria methods that need explicit formulation. The design systems are often hard-coded for a specific problem with specialized optimization and FEM routines. This paper presents a work that uses a system approach to solid free form design. It attempts to develop a general topolo...

IMPROVING COMPUTATIONAL EFFICIENCY OF PARTICLE SWARM OPTIMIZATION FOR OPTIMAL STRUCTURAL DESIGN

This paper attempts to improve the computational efficiency of the well known particle swarm optimization (PSO) algorithm for tackling discrete sizing optimization problems of steel frame structures. It is generally known that, in structural design optimization applications, PSO entails enormously time-consuming structural analyses to locate an optimum solution. Hence, in the present study it i...
