Product Description:
Reliability-based design is the only engineering methodology currently available which can ensure self-consistency in both physical and probabilistic terms. It is also uniquely compatible with the theoretical basis underlying other disciplines such as structural design. It is especially relevant as geotechnical design becomes subject to increasing codification and to code harmonization across national boundaries and material types. Already some codes of practice describe the principles and requirements for safety, serviceability, and durability of structures in reliability terms.This book presents practical computational methods in concrete steps that can be followed by practitioners and students. It also provides geotechnical examples illustrating reliability analysis and design. It aims to encourage geotechnical engineers to apply reliability-based design in a realistic context that recognises the complex variabilities in geomaterials and model uncertainties arising from a profession steeped in empiricism. By focusing on learning through computations and examples, this book serves as a valuable reference for engineers and a resource for students.

Thanks for your opinion piyush2678
I have used information from this book, when I listen a conference over this issue, previusly, in 2006.
The method use probabilistic terms, then you have to keep in mind the geotechnical concepts clearly.
In those procedures the criterion of the engineer has much importance, and it is not possible to be used without a previous knowledge of the soil parameters that are used to model grounds, because the error level is enormous. If you very know the behavior of a ground, you can apply these methods, that with good use, can correctly model the behavior of a given litological profile. With bad use, the results will be not confidents at all.
I think that it's a very interesting information.

oanm2000,

i have a problem here which i think is related. i need to design for a basement of 3 levels. ground water table (from few months observation of standpipe) is around 6m below ground before excavation of basement. u thk i can apply method in the book to predict the GWT for design. i am trying to utilise the water thrust to reduce my piled foundation. wat do u think?

Dear Concreteok
While most information you have on the characteristics of the soil, better it is the result obtained. In summary that is the real goal of the method.
Now, for your case, you must have sustained good information on certain parameters of the lithology under the construction: stratigraphy, sorting of the materials, granulometry, approximated coefficients of permeability, relative density, plasticity. Known these data, and determined the geostatic pressure that it is going to produce the structure on the land, the probable variation of the phreatic level under the construction can be considered. Another point is that the excavations are going to generate a possitive pressure differential that is going “to upwards haul” the level of underground waters. Additionally, the loads by earthquake tend to produce a upwards change in the phreatic level, question that also must be taken into account.
Having then all that information, the prognosis of the change of the phreatic level will adjust more and more to the feasible reality, which will allow more real and less expensive adjustments you to the project.
But all this depends on the error level that can be allowed.
If the project requirements are extreme, to such point that does not allow the minimum error, the use of these procedures is only appropriate for the phase of first draft or basic engineering.
I hope that this that I explained has been able to help you in something
