Strength of Materials

سايت رسمي مهندس امين نعيم آبادي

Krieger Pub Co | 1983-06-01 | ISBN:0898746213 | 1010 pages | PDF | 30,6 Mb

Strength of Materials – Part. 1: Elementary Theory and Problems contains the essential material that is usually covered in required courses of strength of materials in our engineering schools.

Strength of Materials – Part. 2: Advanced Theory and Problems contains the later developments that are of practical importance in the fields of strength of materials, and theory of elasticity. Complete derivations of problems of practical interest are given in most cases.

The books are illustrated with a number of problems to which solutions are presented. In many cases, the problems are chosen so as to widen the field covered by the text and to illustrate the application of the theory in the solution of design problems.

The Handbook of Highway Engineering

سايت رسمي مهندس امين نعيم آبادي

T.F. Fwa (Editor)
Publisher: CRC | Number Of Pages: 888 | Publication Date: 2005-09-28 | ISBN / ASIN: 0849319862 | PDF | 15,8 MB

Beginning with financing, access management, environmental impacts, road safety, and noise, this book explores the expanded responsibilities of the modern highway engineer as well as the increasing trend toward privatization of project development and financing. The next section considers technical issues in highway and pavement engineering, including materials, new mechanistic-empirical design approaches, new closed-form solutions for backcalculation, and deflection and stress computation in multi-slab systems. Rounding out the discussion, the final section examines construction, management, performance evaluation including nondestructive testing, and a chapter devoted to highway asset management.

Fire Resistance of FRP-Strengthened Structural Members

Beam slab assemblies before testing

Beam slab assemblies before testing

Objective

To develop fire-resistance design guidelines for FRP-reinforced concrete structures.

Background

FRPs or fibre-reinforced polymers are high in strength, lightweight and non-corrosive, and their effectiveness as externally bonded repair materials is now widely recognized. However because they are relatively new, and only limited work has been done on their performance in fires, they have not been used in buildings where fire safety is a critical design consideration.

Statement of Work

  • Conducted nine full-scale and four intermediate-scale fire-endurance experiments on columns, slabs, and beam-slab assemblies strengthened with carbon and/or glass FRP wraps and insulated with a specially designed fire-protection system.
  • Developed numerical models to predict the fire resistance of the members, and validated them against experimental data.

Results

The study demonstrated that:

  • FRP-strengthened systems that were adequately insulated achieved a minimum 4-hour fire resistance rating under service load
  • The insulating fire-protection systems maintained low temperatures in the concrete and reinforcing steel, thus enabling the concrete and steel to retain most of their ambient strength during the fire tests
  • Even though the glass transition temperature of the FRPs was exceeded, satisfactory fire resistance ratings were achieved because the insulation stayed in place. The insulation and its proper installation were key to protecting the structure.

Outcomes

  • Numerical models capable of predicting with sufficient accuracy the thermal effects of fire on the assemblies tested
  • Preliminary fire-resistance design guidelines for FRP-strengthened concrete structural members submitted to the American Concrete Institute (ACI) for inclusion in the ACI standards.

Partners

Start/Expected Completion Dates

The project began in July 2002 and was completed in March 2007.

MECHANICS OF COASTAL SEDIMENT TRANSPORT

by Jørgen Fredsøe (Technical University of Denmark) & Rolf Deigaard (Technical University of Denmark)

This book treats the subject of sediment transport in the marine environment, covering transport of noncohesive sediment by waves and currents in- and outside the surf zone. It can be read independently, but a background in hydraulics and basic wave mechanics is required.

The primary aim of the book is to describe the physical processes of sediment transport and how to represent them in mathematical models. The book can be divided in two main parts; in the first, the relevant hydrodynamic theory is described. This part contains a review of elementary theory for water waves, chapters on the turbulent wave boundary layer and the turbulent interaction between waves and currents, and finally, surf zone hydrodynamics and wave driven currents.

The second part covers sediment transport and morphological development.The part on sediment transport introduces the basic concepts (critical bed shear stress, bed load, suspended load and sheet layer, near-bed concentration, effect of sloping bed); it treats suspended sediment in waves and current and in the surf zone, and current and wave-generated bed forms. Finally, the modelling of cross-shore and long-shore sediment transport is described together with the development of coastal profiles and coastlines.

 
Contents:
  • Basic Concepts of Potential Wave Theory
  • Wave Boundary Layers
  • Bed Friction and Turbulence in Wave-Current Motion
  • Waves in the Surf Zone
  • Wave-Driven Currents
  • Current Velocity Distribution in the Surf Zone
  • Basic Concepts of Sediment Transport
  • Vertical Distribution of Suspended Sediment in Waves and Current Over a Plane Bed
  • Current-Generated Bed Waves
  • Wave-Generated Bed Forms
  • Cross-Shore Sediment Transport and Coastal Profile Development
  • Longshore Sediment Transport and Coastline Development
 
Readership: Ocean and electronics engineers, geologists, mathematical physicists and graduate students.
 
“… the book presents an integrated and valuable work on the advanced mechanics of coastal hydrodynamics and sediment transport, well worth the attention of graduate students and professionals specializing in the field.”
Journal of Coastal Research
 
“… the authors have managed to create an informative balance between theory, measurements and numerical modelling … I fully recommend the book, which is published at a very reasonable price as Volume 3 of the Advanced Series on Ocean Engineering by World Scientific. The book will stand alone but if some readers feel that it needs a mate on the book shelf, the best companion may be Volume 4 in the same series, titled Coastal Bottom Boundary Layers and Sediment Transport by P Nielsen.”
International Journal of Marine Geology, Geochemistry and Geophysics
 
“The book is very well-written. Basic ideas are outlined in a straightforward manner and more complex topics are dealt with in the form of worked examples. At no point is the mathematics beyond anyone with a first degree in engineering but familiarity with basic hydraulics and wave mechanics would be an advantage. Both authors have in the past made many major contributions to this field and it is, consequently, hardly surprising that there is a strong emphasis on North-European research literature.”
J. Fluid Mech.
 
“… this is a very interesting text that will assist a number of young scientists dealing with sediment transport … The material is explained quite clearly and the approach is quite analytical, making this text most valubale to coastal engineers and scientists … This book is perfectly suited to all graduate students and scientists interested in coastal engineering. It is the kind of digest that will bring readers back to the book long after graduation.”
Journal of Hydraulic Engineering
