This document (CEN/TR 15728:2008) has been prepared by Technical Committee CEN/TC 229 “Precast concrete products”, the secretariat of which is held by AFNOR.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. To ensure the performance of the precast concrete products, lifting and handling should be taken into account in the design of the product. Inserts are used for lifting and handling of precast elements. They should meet an appropriate degree of reliability. They should sustain all actions and influences likely to occur during execution and use. This Technical Report deals with all lifting inserts cast into precast concrete elements i.e. lifting parts developed and produced at the precasting plant as well as lifting inserts as part of a system supplied by a manufacturer of lifting systems. The intent of this document is to give information to precast product designers.
The failure of inserts for lifting and handling could cause risk to human life and/or lead to considerable economic consequences. Therefore inserts for lifting and handling should be selected and installed properly by skilled personnel.
This Technical Report based on current practices gives recommendations for correct choice and design of lifting inserts according to the lifting capacity of their part embedded in the concrete. It is based on EN 1992-1-1 (Eurocode 2) and on published supplier’s data.
In the Technical Report numerical values for partial safety factors are recommended as basic values that provide an acceptable level of reliability. They have been selected assuming that an appropriate level of workmanship and of quality management (Factory Production Control) applies. They may be applied in the absence of national regulations.

Abstract
The bulk of this book takes the form of a worked example of the design of the beams for a simply-supported single span beam-and-slab deck. The final section is a partial design example of an inverted T beam deck, included in order to illustrate the extra calculations required for a solid slab deck

Abstract
Seawalls play a vital role in controlling changes of coastline caused by marine erosion and deposition. Rising sea levels world-wide can only increase the importance of these coastal defences. Their design is a rapidly developing science in which standardised solutions are often inappropriate, owing to the multiplicity of factors involved and the site-specific nature of each project. This book guides the reader through all aspects of seawall design, including: Their role within an overall coastal management policy, including their relation to other coastal defence options. Problem definition, project planning, data collection and interpretation. Conceptual and detailed design. Design for construction and maintenance. Materials. Financial and economic considerations

this morning, when I try to post new material, I was suprised by following message:
"Please correct the following errors before continuing:
You are trying to post a message too quickly after posting a previous message. Please wait 644 more seconds."
Probably, there is some important reason for introducing this new rule, but from my point of view this means only one - to wasting my time.
I allow to myself to suggest to Forum team to revise this new rule.
In a semi-continuous frame the degree of continuity between the beams and columns is greater than that assumed in simple design, but less than that assumed in continuous design. The degree of continuity can be chosen to produce the most economic balance between the primary benefits associated with these two traditional alternatives.
This document presents a method of analysis and design which permits semi-continuous braced steel frames to be designed by hand. The method is only marginally more complex than that for simple design, and the connection details are straightforward (and therefore inexpensive). Connection forces and moments can be chosen so that column stiffening is not required. Despite this economy of both design effort and fabrication costs, when compared with simple design, it is possible to achieve:
- reduced beam depths
- reduced beam weights.
Procedures are given for checks at both the ultimate and serviceability limit states. For normal design the practising engineer need only consult the main body of the document and the standard connection capacity tables given in Appendix C (yellow pages). A worked example of the approach is included in Appendix A. Appendix B gives a full procedure for estimating deflections more accurately, should this be required.

Description
The field of stress analysis has gained its momentum from the widespread applications in industry and technology and has now become an important part of materials science. Various destructive as well as nondestructive methods have been developed for the determination of stresses. This timely book provides a comprehensive review of the nondestructive techniques for strain evaluation written by experts in their respective fields.
The main part of the book deals with X-ray stress analysis (XSA), focussing on measurement and evaluation methods which can help to solve the problems of today, the numerous applications of metallic, polymeric and ceramic materials as well as of thin-film-substrate composites and of advanced microcomponents. Furthermore it contains data, results, hints and recommendations that are valuable to laboratories for the certification and accreditation of their stress analysis.
Stress analysis is an active field in which many questions remain unsettled. Accordingly, unsolved problems and conflicting results are discussed as well. The assessment of the experimentally determined residual and structural stress states on the static and dynamic behavior of materials and components is handled in a separate chapter.
Students and engineers of materials science and scientists working in laboratories and industries will find this book invaluable.
