BURIED PIPE DESIGN 3/E

O livro apresenta conceitos claros e objetivos , mostrando que houve interesse e cuidado ao exporas diversas teorias pertinentes aos assuntos abordados. É com satisfação que consulto o livro.

This book is an excellent source of information on buried pipe analysis and design from theory to application. It rounds out the reader's perspective with valuable full size pipe research data. Fundamentals of buried pipe analysis and design are clearly presented as well as information on nonlinear finite element analysis of soil-structure interaction of the pipe-soil system. An excellent book for practitioners with a problem to solve!

As advertised.

Great explanations and formulae for design or failure analysis. Covers design of pipe whether drain pipe or pressure pipe. Standard on the topic.

the book is very good, there are few books of its type, the book contains good examples

I have a copy of the Second Edition. While the book does contain a wealth of information as the other reviews indicated, the Second Edition has a lot of errors.There are errors in formulas, errors in example problems, inconsistencies in the use of subscripts, important tables placed in odd places (Table 3.2 on page 70), sloppy editing, and a generally casual attitude toward consistency in terms and units, such as "load" (the term most commonly used in the book to mean pounds per linear foot of pipe) sometimes used interchangeably with pressure (pounds per square foot).Hopefully the third edition fixes these problems, and they should mail everyone who bought the second edition a list of errata.One error in the book is in example 3.1 on page 81 which you can see by searching for "Buried Pipe Design" (second edition) on Google Books.The equation for the Three Edge Bearing is given asW3-edge= Wc * SF/BFAnd the "D load" is given asWdload = Wc * SF/BF * Dbut it should beWdload = Wc * SF/BF / DThe value of D in the example is 1.25.The Dload equation in the example is wrong because the next two lines show the value of Dload being less than Three Edge bearing, 2074 instead of 3240, which is consistent with dividing by the diameter D, not multiplying. Also on page 78 (not visible in google books) it clearly states that "The D Load is the three-edge bearing strength divided by diameter."Another mistake is in example 2.9 on page 59.The buoyant unit weight should be:yb=yd-yw/(1+e)not:yb=[yd-yw]/(1+e)Again, the answer is correct but the intermediate equations are not, very confusing someone trying to learn and understand every step. It makes one wonder what other parts of the book were similarly proofread.More errors and sloppiness are on pages 20 and 21 (visible in google books).The subtitle of the chart in Figure 2.6 is "Values of Bd/Bc for ditch conduit LEADS TO EQUAL PROJECT conduit loads". But it should surely read "Values of Bd/Bc for ditch conduit LOADS EQUAL TO PROJECTION conduit loads" (capitalization mine)And an error at the bottom of page 20,"If the Calculation of Bd/Bc is:Greater than that of Fig. 2.6, use Wd.Less than that of Fig. 2.6, use Wc."But the is clearly backwards, because it states just above that if the actual trench width (Bd) is:GREATER than transition width, use Eq. 2.5 (Wc)LESS than transition width, use Eq. 2.4 (Wd)So, buyer beware for the Third Edition.All in all, the errors in this book, and in other establishment pipe publications, make it rather embarrassing to be a pipe guy, and the fact that no one seems to have caught these problems suggests to me that few pipe engineers are actually crunching numbers and are instead just reading values from tables.

I received a copy of Dr. Moser's text "Buried Pipe Design, Second Edition". Upon a brief inspection, I was impressed with the breath, number of figures, illustrations, numerous example problems and extensive number of references at the end of each chapter.The addition of SPIDA (soil-pipe interaction design and analysis) in Chapter 5 (Rigid Pipe Products) is very valuable. The introduction to new pipe materials, particularly the discussion of profile-wall polyethylene pipe is appreciated.Finally, the introduction of information on pipe handling and trenching(Chapter 8: Pipe Installation and Trenchless Technology) is welcome.

This book covers a lifetime of pioneering research conducted by the author, Dr. Al Moser, on all types of municipal pipe materials. Dr. Moser studied under legends like Dr. Reynold Watkins and Dr. Marlin Spangler and has conducted research on every aspect of pipelines, the results of which are used by design engineers all over the world. This is a must-have for municipal water and wastewater pipeline engineers.

Excellent!!
