An introduction to the practical use of Yield Line Theory in the design of economic reinforced concrete slabs, including examples of design of flat slabs, raft foundations and refurbishment.
The aim of this publication is to (re-) introduce practical designers to the use of Yield Line Design. The intention is to give an overall appreciation of the method and comprehensive design guidance on its application to the design of some common structural elements. It assumes that the user has sufficient experience to recognise possible failure patterns and situations where further investigation is required.
The basic principles of Yield Line theory are explained and its application as a versatile method for the design and assessment of reinforced concrete slabs is demonstrated. Theory is followed by practical examples and the accompanying commentary gives insights into the years of experience brought to bear by the main author, Gerard Kennedy.
The publication is intended as a designer’s aid and not an academic paper. It commits to paper a practical approach to the use of Yield Line for the design of concrete slabs. It gives guidance on how to tackle less simple problems, such as the design of flat slabs, rafts, refurbishment and slab-beam systems. Whilst the publication covers the design of common elements, it is an introduction, not a comprehensive handbook: in more exacting circumstances, designers are advised to consult more specialist literature. The examples are practical ones that may be followed, but should not be extended too far without reference to more specialist literature.
Yield Line Theory challenges designers to use judgement and not to rely solely on computer analysis and design. Once grasped, Yield Line Theory is exceedingly easy to put into practice and everyone in the procurement chain benefits. Simple design leads to simple details that are fast to detail and fast to fix. Current initiatives such as Egan [4] and partnering, etc, should challenge designers to revisit and re-evaluate the technique.

I will constantly add my new review at there.
I hope my thread can be a "sticky/permanent thread" so that easily to find & read by all members of CivilEA
I need suggestion from Admin/Protector/Moderator where is the correct forum for my thread & also correct name for my thread.
I feel that my thread in that temporary location ( in Suggestion Forum ) should be moved to an appropriate forum so that easily to find & read by all members of CivilEA.
If that thread moved by Admin/Protector/Moderator to an appropriate/correct forum please give me notification about the new location of it so that I can continue add my review.
I hope my review useful for all of you
Thx

GEO-INSTITUTE OF ASCE GROUTING COMMITTEE JET GROUTING TASK FORCE
JET GROUTING GUIDELINE
This document has been prepared by the Jet Grouting Task Force, a subcommittee of the Geo-Institute of the American Society of Civil Engineers (ASCE) Grouting Committee. The Jet Grouting Task Force was assembled in 2005 by the Grouting Committee to represent a cross section of the industry. Task Force members include Owners, Engineers, Consultants, and Specialty Contractors all engaged in jet grouting activities. The intent of this document is to provide a jet grouting guideline approved by the Jet Grouting Task Force that is fair to all parties involved on a jet grouting project. This document is not intended to cover every conceivable application or requirement of jet grouting. However, it does provide standard practice requirements for qualifications, materials, equipment, testing, and production procedures for the Professional Engineer to incorporate into their project specific requirements. The Task force has included commentary within this document. The commentary is shown in italic and appears immediately after sub-articles requiring further discussion. The commentary is here to provide a better understanding of specific language chosen for the body of the guideline and also provides alternate requirements and language that can be incorporated by the Professional Engineer.

Civil Engineering Body of Knowledge for the 21st Century
Preparing the Civil Engineer for the Future
The manner in which civil engineering is practiced must change. That change is necessitated by such forces as globalization, sustainability requirements, emerging technology, and increased complexity with the corresponding need to identify, define, and solve problems at the boundaries of traditional disciplines. As always within the civil engineering profession, change must be accomplished mindful of the profession’s primary concern for protecting public safety, health, and welfare. The profession recognizes the need for change. For example, in June 2006, the American Society of Civil Engineers (ASCE) convened the Summit on the Future of Civil Engineering – 2025. This gathering of civil engineering and other leaders, including international participants, articulated a global vision for the future of civil engineering. The vision1 sees civil engineers as being entrusted by society as leaders in creating a sustainable world and enhancing the global
quality of life.
