This publication has been developed to provide guidance as to how the direct displacement-based design methodology can be codified. It is intended for insertion within the seismic requirements of a code, establishing how design forces can be obtained using a Direct Displacement-Based Design (DDBD) approach. The document has currently been drafted with reference to several clauses of Eurocode 8. This document is presented in a traditional “Code + Commentary” format, on a split two-column page. The commentary aims to generally clarify the code requirements and indicate references where the background and further discussion on the requirements can be found

A visual feast of design
A liberally illustrated account of how concrete can be used to create aesthetically pleasing designs
A source of inspiration for architects, designers and engineers
Summary
This is a broadly chronological account of the decorative and innovative use of Portland cement-based concrete. Contrary to the oft-held belief that concrete is a dull material that is used unimaginatively, this book demonstrates that it can be used in an exciting and inspiring way while benefiting from being a highly durable building material.
After tracing the decorative use of concrete back several thousand years, its development is followed into the 20th century with the invention of Portland cement and its subsequent use in vast volumes. As concrete was used more widely, it also was used more creatively and accounts are included of some of the early exponents of the material such as Frank Lloyd Wright, Le Corbusier, Nervi, Lubetkin, and Arup. The brilliance of these and other designers and engineers has provided a legacy of economy and form that is akin to today's current vogue of minimalism.
The variety of scale and form is remarkable and after considering decorative processes and techniques, the book moves into the sphere of art, demonstrating the flexibility of the material.
The book contains a wealth of illustrations, and in the later chapters the author considers the work of selected designers and then presents a large number of examples from around the world. The final chapter looks ahead, taking in current developments in high strength concrete that allow thin, slender applications, also novel self-cleaning concrete and even transparent concrete!
Of one thing we can be certain - concrete is not dull!

Strengthening of Concrete Structures with Adhesively Bonded Reinforcement :
Design and Dimensioning of CFRP Laminates and Steel Plates
Author: Konrad Zilch, Roland Niedermeier and Wolfgang Finckh | Size: 2 MB | Format:PDF | Quality:Unspecified | Publisher: Wiley | Year: 2014 | pages: 158 | ISBN: 3433030863, 9783433030868
Selected chapters from the German concrete yearbook are now being published in the new English "Beton-Kalender Series" for the benefit of an international audience. Since it was founded in 1906, the Ernst & Sohn "Beton-Kalender" has been supporting developments in reinforced and prestressed concrete. The aim was to publish a yearbook to reflect progress in "ferro-concrete" structures until - as the book's first editor, Fritz von Emperger (1862-1942), expressed it - the "tempestuous development" in this form of construction came to an end. However, the "Beton-Kalender" quickly became the chosen work of reference for civil and structural engineers, and apart from the years 1945-1950 has been published annually ever since.

The finite element method (FEM) is a computational tool widely used to design and analyse complex structures. Currently, there are a number of different approaches to analysis using the FEM that vary according to the type of structure being analysed: beams and plates may use 1D or 2D approaches, shells and solids 2D or 3D approaches, and methods that work for one structure are typically not optimized to work for another. Finite Element Analysis of Structures Through Unified Formulation deals with the FEM used for the analysis of the mechanics of structures in the case of linear elasticity. The novelty of this book is that the finite elements (FEs) are formulated on the basis of a class of theories of structures known as the Carrera Unified Formulation (CUF). It formulates 1D, 2D and 3D FEs on the basis of the same ′fundamental nucleus′ that comes from geometrical relations and Hooke′s law, and presents both 1D and 2D refined FEs that only have displacement variables as in 3D elements. It also covers 1D and 2D FEs that make use of ′real′ physical surfaces rather than ’artificial’ mathematical surfaces which are difficult to interface in CAD/CAE software. Key features: Covers how the refined formulation can be easily and conveniently used to analyse laminated structures, such as sandwich and composite structures, and to deal with multifield problems Shows the performance of different FE models through the ′best theory diagram′ which allows different models to be compared in terms of accuracy and computational cost Introduces an axiomatic/asymptotic approach that reduces the computational cost of the structural analysis without affecting the accuracy Introduces an innovative ′component–wise′ approach to deal with complex structures Accompanied by a website hosting the dedicated software package MUL2 (

Cost Optimization of Structures: Fuzzy Logic, Genetic Algorithms, and Parallel Computing
Author: Hojjat Adeli, Kamal C Sarma | Size: 2.5 MB | Format:PDF | Quality:Original preprint | Publisher: Jhon Wiley & Sons | Year: 2006 | pages: 222 | ISBN: 9780470867334
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.

The fields of architecture and engineering are undergoing dramatic change. New technologies and methodologies are transforming the way that projects are designed and delivered. These technologies enable the integration of complex systems in the design of more holistic, performative buildings. In order to achieve this synergy, practicing architects and engineers collaborate closely and often. Collaborations in Architecture and Engineering contains robust design exercises for architects and engineers focusing on team-building and problem solving to prepare you for working together in practice. It provides an overview and foundation for interdisciplinary collaboration so that you can create innovative proposals for optimization, performance, and aesthetic goals. It also shows you how to solve real-world problems and how to engage creatively with technological challenges so that you can be a productive member of any team.
The authors, an architect and an engineer, share guidelines learned from their experiences and observations on how to ensure productive communication, engage in interdisciplinary discussions, and establish common goals and values. In addition to exercises, scattered throughout are case study examples of architect and engineer collaborations--such as those between SANAA and Mutsuro Sasaki, Foster + Partners and Buro Happold, Steven Holl and Guy Nordenson, and SHoP Architects and ARUP. The book also includes a discussion about integrated project delivery (IDP) contracts and administration, and a bibliography so you'll be ready for better integration.

Project Quality Management: Critical Success Factors for Buildings
Author: Sui Pheng Low & Joy Ong | Size: 11 MB | Format:PDF | Quality:Original preprint | Publisher: Springer | Year: 2014 | pages: 186 | ISBN: 9789812870742 , 9789812870735
> Presents the Construction Quality Assessment System (CONQUAS), a quality performance measurement system that focuses on critical success factors for building best practices in the construction industry
> First book that illustrates project quality management in the construction industry, where 33 Critical Success Factors (CSFs) were identified, evaluated and quantified in details for implementation by building professionals as a checklist
> Written by leading experts in the field
The book presents the development of the Construction Quality Assessment System (CONQUAS), Singapore’s de facto quality performance measurement system, explains the application of the Quality Management System (QMS) to manage CONQUAS and identifies 33 critical success factors (CSFs) for achieving high CONQUAS scores. Through CONQUAS, the reader benefits from understanding how the Singapore government developed and implemented the first objective system for measuring what many building professionals have perceived to be elusive quality standards in the construction industry. The book presents both the theoretical concepts as well as the practical aspects to achieving strategic Project Quality Management that is anchored on the CSFs to building best practices. To realistically reflect the practical aspects and challenging issues faced by stakeholders in the construction industry, questionnaire surveys were conducted with building professionals to distinguish the importance level and extent of adoption of the 33 CSFs (identified from a comprehensive review of the extant literature) in influencing and affecting the achievement of high CONQUAS scores. These were further anchored by in-depth interviews with quality experts in the Singapore construction industry to provide a better understanding of issues relating to strategic Project Quality Management. Collectively, the empirical findings collated from the building professionals suggest that while the CSFs identified are known tenets of quality, these were still not being followed in their totality. A further case study was conducted through a formal set of in-depth interviews with the quality assurance team of a construction company who has direct involvement before, during and after their tremendous improvements in the CONQUAS scores attained. The strength of this book therefore represents a true account and reflections of real-life practices and experiences in the construction industry for contractors, quality managers and policy-makers to learn from. Although the context of this book relates to the Singapore experience, the lessons and recommendations are equally relevant and applicable to the global construction industry in both the developing and developed countries whose stakeholders (in both the public and private sectors) wish to understand how CONQUAS works, and how the CSFs identified can likewise be implemented for strategic Project Quality Management to building best practices. The book is therefore of interests to researchers, academia and practitioners in the construction industry as well as in other sectors of the economy (in Singapore and other countries) where learning points may be used for enhancing project quality management for buildings.
