Performance-Based Optimization of Structures introduces a method to bridge the gap between structural optimization theory and its practical application to structural engineering. The Performance-Based Optimization (PBO) method combines modern structural optimisation theory with performance based design concepts to produce a powerful technique for use in structural design. This book provides the latest PBO techniques for achieving optimal topologies and shapes of continuum structures with stress, displacement and mean compliance constraints. The emphasis is strongly placed on practical applications of automated PBO techniques to the strut-and-tie modelling of structural concrete, which includes reinforced and prestressed concrete structures. Basic concepts underlying the development of strut-and-lie models, design optimization procedure, and detailing of structural concrete are described in detail. Alternative approaches to topology optimization are also introduced. The book contains numerous practical design examples illustrating the nature of the load transfer mechanism of structures.

Novel research in construction management is often distant from existing practice. This collection of reviews serves to bridge this gap under three major themes: innovation, organisation and human behaviour, and methods and tools. It outlines a series of successful collaborative projects between industry and the academic and research communities. Many of the authors have worked in technology transfer, as change agents, resolving industrially-relevant problems by using scientifically-based research. The book reveals the source of ideas, data and results to provide a useful resource for researchers, academics and graduate students, and a challenging guide for senior industry managers.

Occupational accidents have a massive personal and social cost as well as a major financial cost. The construction industry is one of the most dangerous industries, accounting for around 20-30% of all occupational deaths worldwide. The accompanying financial cost is either absorbed directly or passed on in the form of higher insurance costs. In addition, regulatory bodies have started to impose legal accountability on all the parties along the construction supply chain. OHS is hard to implement. Construction projects are complex, with a fluid workforce, and the regulatory framework is highly elaborate. OHS Electronic Management Systems for Construction presents a theoretical framework which is designed to overcome these difficulties, integrating OHS management in construction using knowledge management and web technologies. This framework is explained in a clear step-by-step way, as are features such as a systematically developed corporate safety memory, and a virtual learning portal to facilitate on-demand safety training. The ultimate aim of this book is to aid the development of an established safety culture at the organisational level, and the formation of an industry-wide community of safety practice. This is essential reading for OHS professionals and construction managers attempting to change their industry for the better, as well as advanced students and researchers.

The last three decades have seen the evolution of Public–Private Partnerships (PPPs) and Relationship Contracting (RC) as alternative procurement approaches to traditional methods of delivering public infrastructure. The potential for growth in these new forms of procurement has led to an on-going debate on the nature of requirements, particularly in terms of policy development, encouraging private investment and value for money. A key argument for Governments to procure projects using PPPs and RC is that the process delivers better value for all the stakeholders, including the community and asset end-users. This wide-ranging study of such crucial procurement issues includes international historical context, collaboration and risk management, with a focus on sustainable procurement approaches. The international significance of PPPs and RC procurement is reinforced with case study examples from the UK, Europe, North America, South Africa and the Asia-Pacific. It features cutting-edge research from around the world on subjects such as: Reviews and reflection of the PPP approach Project Alliancing Implementation of RC in developing countries Changes in procurement policy Value for money, collaboration and stakeholder involvement Growth and emergence of PPPs in Asia Risk management Including contributions from some of the world's most prominent academics and practitioners in this field, it is a crucial guide to the strategic choices governments now face for the provision of infrastructure, between using ‘public’ or ‘private’ mechanisms, or a combination of the two.

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 algorithms Focuses on novel computing techniques such as genetic algorithms, fuzzy logic, and parallel computing Covers both Allowable Stress Design (ASD) and Load and Resistance Factor Design (LRFD) codes Includes realistic design examples covering large-scale, high-rise building structures Presents computational models that enable substantial cost savings in the design of structures Fully 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.
