  seawall design

seawall design

Author: RS THOMAS AND B HALL | Size: 8.41 MB | Format: PDF | Year: 1992 | pages: 373 | ISBN: 9780750610537

[Image: 70547215575764521436.jpg]


[Image: info.png]

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

  Waiting for new post
Posted by: ir_71 - 04-16-2011, 06:29 AM - Forum: FAQs, Q&A, comments - Replies (1)

Dear Forum team,

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.

Best regards
IR.

  SCI P183: Design of Semi-continuous Braced Frames
Posted by: ir_71 - 04-16-2011, 05:39 AM - Forum: Steel - Replies (2)

SCI P183: Design of Semi-continuous Braced Frames

Author: G H Couchman | Size: 1.5 MB | Format: PDF | Publisher: SCI | Year: 1997 | pages: 72 | ISBN: 1859420591

[Image: 58848391606291579793.jpg]


[Image: info.png]

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.

  Structural and Residual Stress Analysis by Nondestructive Methods: Evaluation - Appli
Posted by: ir_71 - 04-16-2011, 04:59 AM - Forum: Analysis & Design - Replies (1)

Structural and Residual Stress Analysis by Nondestructive Methods: Evaluation - Application - Assessment

Author: Viktor Hauk | Size: 30.4 MB | Format: PDF | Publisher: Elsevier Science | Year: 1997 | pages: 640 | ISBN: 0444824766

[Image: 84851374386035452887.jpg]


[Image: info.png]

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.

Preface. 1. Introduction. 2. X-ray diffraction (V. Hauk, H. Behnken, W. Reimers, W. Pfeiffer, Ch. Genzel). 3. Neutron diffraction methods (L. Pintschovius). 4. Ultrasonic techniques (E. Schneider). 5. Micromagnetic techniques (W.A. Theiner). 6. Assessment of residual stresses (B. Scholtes). Subject index.

  SCI P287: Design of Composite Beams using Precast Concrete Slabs
Posted by: ir_71 - 04-15-2011, 06:10 PM - Forum: Analysis & Design - Replies (2)

SCI P287: Design of Composite Beams using Precast Concrete Slabs

Author: S J Hicks, R M Lawson | Size: 1.86 MB | Format: PDF | Publisher: SCI | Year: 2003 | pages: 101 | ISBN: 1859421393

[Image: 37210182758783507213.jpg]


[Image: info.png]

This publication provides guidance on the design of steel beams acting compositely with precast concrete slabs in multi-storey buildings. The use of hollow core or solid plank precast units offer benefits in terms of cost (the long spanning capabilities of the precast slabs lead to fewer secondary beams) as well as the advantages offered by composite construction. The design basis is generally in accordance with BS 5950-3, supplemented by recommendations from Eurocode 4 and data from tests. Particular issues affecting the use of precast concrete concern the requirements of effective shear connection and transverse reinforcement. Small-scale push-out tests, and earlier composite beam tests, have established reduction factors for the design resistance of welded shear connectors as a function of the gap between the ends of the precast concrete units, and the amount of transverse reinforcement provided.
The guidance also emphasises the importance of the design of the steel beam in the non-composite construction stage, where out-of-balance loads can occur during installation of the precast concrete units. The guidance applies to hollow core units of 150 to 260 mm depth, and to solid precast planks. A step-by-step design procedure is given for composite beams using various forms of precast concrete units, with or without a concrete topping. This is supplemented by a fully worked design example for a composite beam in a 15.8 m × 7.2 m grid, and a series of design tables for concept design.
