This is the kind of book that one can use to hand to a graduate student starting to work on the subject of beams and plates on elastic foundations. It has a wealth of information, well organized, and not having too much detail. In addition, and most importantly, it has an extensive list of references, about 800 in all, covering the literature both in the Soviet Union and in the West.
The book is written for engineers, not mathematicians, so that the emphasis is on methods of analysis which lead to numerical, and particularly graphical, results for quantities of engineering interest—contact stresses, deflections, etc. Little emphasis is placed on topics such as integral transforms, dual integral equations, etc. Where such topics are introduced they are treated merely as tools which may be used to obtain solutions to problems.
The main body of the book is devoted to a study of the wide variety of problems relating to an elastic structure lying on a foundation, which again is almost always assumed to be elastic. The variety of problems arises because the structure may be taken to be rigid or elastic, and may be a beam, thin or thick, finite or infinite; a plate, circular or rectangular, thin or thick, finite or infinite. The foundation also may take various forms; it may be a simple Winkler foundation made up of independent linear springs, it may be some more complicated, Vlasov-Leont'ev or two-parameter model, or it may be a continuum, isotropic or anisotropic, homogeneous or nonhomogeneous. Virtually all the important combinations are studied and compared with each other. Most of the work is quasi-analytical, but purely numerical methods such as the finite-difference and finite-element methods are introduced and used. A final chapter deals with the determination of soil parameters, particularly by experimental methods, and a series of appendices give the details of the mathematical analysis of some of the basic plate-foundation problems.
Indian Standard Codes of Construction & Civil Engineering
(All 27 CODES)
A building has to perform many functions satisfactorily. Amongst these functions are the utility of the building for the intended use and occupancy, structural safety, fire safety and compliance with hygienic, sanitation, ventilation and daylight standards. The design of the building is dependent upon the minimum requirements prescribed for each of the above functions. The minimum requirements pertaining to the structural safety of buildings are being covered in loading codes by way of laying down minimum design loads which have to be assumed for dead loads, imposed loads, wind loads and other external loads, the structure would be required to bear. Strict conformity to loading standards, it is hoped, will not only ensure thestructural safety of the buildings and structures which are being designed and constructed in the country and thereby reduce the hazards to life and property caused by unsafe structures, but also eliminate the wastage caused by assuming unnecessarily heavy loadings without proper assessment.

IEEE Std 691™-2001 (R2007) - IEEE Guide For Transmission Structure Foundation Design And Testing
This design guide is intended for the use of the practicing professional engineer engaged in the design of foundations for electrical transmission line structures. This guide is not to be used as a substitute for profes-sional engineering competency, nor is it to be considered as a rigid set of rules. Of all building materials, soilis the least uniform and most unpredictable; therefore, the methods described in this guide may not be the only methods of design and analysis, nor may they be appropriate in all situations. Design and analysis must be based upon sound engineering principles and relevant experience.

Guide to the Concrete Capacity
Design (CCD) Method
Embedment Design Examples - ACI 349.2R-07
This report was prepared by the members of the ACI 349 Subcommittee on Steel Embedments to provide examples of the application of ACI 349 to the design of steel embedments. The first edition of this report, published in 1997, was based on ACI 349-97 that used the 45-degree cone breakout model for determining the concrete breakout strength. The 2001 edition of the Code* marked a major departure from the previous editions with the adoption of the concrete capacity design (CCD) method. The model for the concrete breakout strength used in the CCD method is a breakout prism having an angle of approximately 35 degrees. In addition, the concrete breakout strength for a single anchor away from the edge is proportional to the embedment depth raised to the power of 1.5 and not embedment depth squared, as used in the previous versions of the Code. These and other changes in the Code result in designs that are somewhat different than those obtained using previous editions of the Code. The examples used in this report are based on the ACI 349-06, Appendix D, and illustrate how the CCD method is applied. In previous editions of ACI 349, the anchorage design was given in Appendix B. Because ACI 349 is a dependent code, the chapters and Appendixes in ACI 349 are updated to be consistent with ACI 318.

Easy CurveFit is a small application designed to allow you to easily plot a curve through any graph of results that you enter into the application.
When first opened, Easy CurveFit is a complete mystery. It's totally unclear what to do with it, as the interface is very abstract and unresponsive. Hovering doesn't give you any clues, and right clicking elicits no response. There is a manual included however, but unfortunately it's very brief and written in bad English that makes little sense!
Basically, to use Easy CurveFit, you have to create a .txt file with your numerical results entered. Then this can be opened, and the points plotted on a graph. You can then, by clicking the various algebraic buttons, create a curve that bets fits your results.
This curve image can be saved, and you can zoom in and out too. While that curve drawing works fine, it's difficult to see what's special about it. While the curve results are good, it's a very clunky interface to use - it would be much improved if you could manually enter results to be plotted, instead of doing so in a text editor first. There are also a distinct lack of options.
If you want to create best fit curves, and save or print your results, Easy CurveFit does the job, but it's not easy to use or well explained at all.
