While the weight of a structure constitutes a significant part of the cost, a minimum weight design is not necessarily the minimum cost design. Little attention in structural optimization has been paid to the cost optimization problem, particularly of realistic three-dimensional structures. Cost optimization is becoming a priority in all civil engineering projects, and the concept of Life-Cycle Costing is penetrating design, manufacturing and construction organizations.In this groundbreaking book the authors present novel computational models for cost optimization of large scale, realistic structures, subjected to the actual constraints of commonly used design codes.As the first book on the subject this book:Contains detailed step-by-step algorithmsFocuses on novel computing techniques such as genetic algorithms, fuzzy logic, and parallel computingCovers both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) codesIncludes realistic design examples covering large-scale, high-rise building structuresPresents computational models that enable substantial cost savings in the design of structuresFully automated structural design and cost optimization is where large-scale design technology is heading, thus Cost Optimization of Structures: Fuzzy Logic, Genetic Algorithms, and Parallel Computing will be of great interest to civil and structural engineers, mechanical engineers, structural design software developers, and architectural engineers involved in the design of structures and life-cycle cost optimisation. It is also a pioneering text for graduate students and researchers working in building design and structural optimization.
