Author(s)/Editor(s): Concrete Institute of Australia | Size: 9.12 MB| Format:PDF| Quality:Original preprint| Publisher: Concrete Institute of Australia| Year: 2010| pages: 187 | ISBN: ISBN 0 909375 69 0
The basic requirements of goo d reinforced concrete detailing are clarity and conciseness. Unfortunately, there has been a steady deterioration in the quality and quantity of drawings supplied for reinforced concrete over the last twenty years. The net result of poor quality drawings is increased costs in the material supply and construction sectors and unacceptable levels of dispute.
Detailing of reinforcement is the interface between the actual design of the concrete structure and what is to be constructed. There is no point in having the most sophisticated analysis and design if it
cannot be constructed in the field. Designers must be aware of practical limitations of construction. Detailing is also important for durability, as poor placement of reinforcement leads to insufficient cover and long term problems. Detailing of reinforcement is not taught to designers and yet it is fundamental to the proper design of reinforced concrete.
Unlike some countries (and in particular the United Kingdom) reinforcement is scheduled by the reinforcing suppliers based on the concrete drawings provided. If the drawings are poor, the actual reinforcing provided on site may not match the designer’s expectations.
The aim of this manual is to guide designers, draftsmen and other professionals toward a uniform method of communicating the design intention to the construction team so that confusion cannot arise from the misinterpretation of the drawings.

Earthquakes are catastrophic events that cause huge economic losses due to the vulnerability of the existing building stock. However, collapses of vulnerable buildings can be avoided if preventative measures, such as enhancement of their earthquake resistance, are implemented on time. This book will allow the reader to become acquainted with a number of unique, modern and cost-effective seismic isolation strategies, which can be easily, and in very short periods of time, and without interruption of the use of the buildings, implemented with high efficiency in existing buildings, making them earthquake proof. An important aspect here is that the books seismic isolation strategies are demonstrated on real examples of existing buildings with different structural systems, such as reinforced concrete frame buildings with shear walls and stone buildings with load-bearing walls. The cost-effectiveness of the suggested strategies is further proved by comparative analyses carried out for buildings both with and without seismic isolation systems.

This book contains auxiliary calculation tools to facilitate the safety assessment of reinforced concrete sections. Essential parameters in the design to the ultimate limit state of resistance such as the percentage of reinforcement and the position of the neutral axis in concrete cross-sections, as well as the control of the maximum stresses in service limit states are provided by these tools. A set of tables, charts and diagrams used to design cross-sections of reinforced and prestressed concrete structures are supplied. The most current beams and columns cross-sections namely, rectangular, circular and T-sections are considered. These tools have been prepared in line with the provisions of the new European regulations, with particular reference to Eurocode 2 – Design of Concrete Structures.
The book stands as an ideal learning resource for students of structural design and analysis courses in civil engineering, building construction and architecture, as well as a valuable reference for concrete structural design professionals in practice.

This guide provides information on how to accommodate bicycle travel and operations in most riding environments. It is intended to present sound guidelines that result in facilities that meet the needs of bicyclists and other highway users. Sufficient flexibility is permitted to encourage designs that are sensitive to local context and incorporate the needs of bicyclists, pedestrians, and motorists. However, in some sections of this guide, suggested minimum dimensions are provided. These are recommended only where further deviation from desirable values could increase crash frequency or severity. This guide has been updated from the previous guide published in 1999. The fact that new guidance is presented herein does not imply that existing bicycle facilities are inadequate or unsafe, nor does it mandate the initiation of improvement projects. The intent of this document is to provide guidance to designers and planners by referencing a recommended range of design values and describing alternative design approaches.

A State Department of Transportation's (DOT) ability to successfully manage and deliver its program is largely dependent on an ability to develop realistic estimates of project cost. Cost estimating involves not only the collection of relevant factors relating to the scope of a project and the cost of resources, but it also requires anticipating cost impacts that may occur due to changes in project scope, available resources, and national and global market conditions. This publication provides “practical” guidance that serves those charged with the development of DOT cost estimates and with the management of the estimating process. This guidebook has two parts. Part I focuses on key cost-estimate techniques and Part II focuses on cost management activities.

The roadside vegetation manager today is faced with dwindling resources, increasing environmental and legal constraints, and increasing public pressure to provide safe and aesthetically pleasing roadsides. Throughout the United States, and the world, roadside vegetation managers face similar challenges and opportunities. These guidelines draw on the long-term experience and expertise of these vegetation managers to provide the basic knowledge required to establish a roadside vegetation management program.
Includes supplemental Appendices materials that include a state DOT survey that provides valuable summary responses from 30 states on vegetation issues; a detailed list of 40 common invasive weeds and how to treat them; and a detailed list of defined technical terms.

Graphic methods for structural design essentially translate problems of algebra into geometric representations, allowing solutions to be reached using geometric construction (ie: drawing pictures) instead of tedious and error-prone arithmetic. This was the common method before the invention of calculators and computers, but had been largely abandoned in the last half century in favor of numerical techniques. However, in recent years the convenience and ease of graphic statics has made a comeback in architecture and engineering. Several professors have begun using graphic statics in the classroom.and.studio environment. But until now, there had been no guidebook that rapidly brings students up to speed on the fundamentals of how to create graphical solutions to statics problems.
Graphic Statics introduces all of the traditional graphic statics techniques in a parametric drawing format, using the free program GeoGebra. Then, advanced topics such as indeterminate beams and three dimensional curved surfaces are be covered. Along the way, links to wider design ideas are introduced in a succinct summary of the steps needed to create elegant solutions to many static equilibrium problems.
Meant for students in civil and architectural engineering, architecture,and construction, this practical introduction will also be useful to professionals looking to add the power of graphic statics to their work.

Reinforced concrete structures are one of the major structural types and must adhere to design regulation codes. It is ideal to find the best design (section dimension, material type, and amount of reinforcement) with the minimum cost providing the design constraints (design formulation considering loading of structure). Metaheuristic methods inspired by natural phenomena can consider design constraints by combining the analyses of formulation of reinforced concrete structures with an iterative numerical algorithm using several convergence options of random generation of candidate design solutions.
Metaheuristic Approaches for Optimum Design of Reinforced Concrete Structures: Emerging Research and Opportunities is a pivotal reference source that focuses on several metaheuristic algorithms and the design of several types of structural members. Additionally, retrofit applications and seismic design issues are considered for readers in earthquake zones. Highlighting a wide range of topics including algorithms, design variables, and retrofit design, this book is ideally designed for architects, engineers, urban designers, government officials, policymakers, researchers, academicians, and students.
