This valuable second edition provides important extensions of unique techniques of numerical analyses of beams, long strips, circular plates, and circular-cylindrical tanks resting on elastic foundations and/or unyielding/elastic supports. Emphasis is placed upon simplicity of analysis without compromising the accuracy of results and a large number of examples are included for illustration. These also provide help for users of the easy-to-use software included. The fully revised software runs smoothly under current Windows operating systems. Employing the numerical techniques outlined in the book, this powerful tool makes design analysis of the related structures easy and time-efficient. The applicability of the software is extended to analysis of laterally loaded piles and bending analysis of retaining walls. A bonus suite of complementary software containing programmes for elastic-plastic soil - structure interaction analyses of beams/strips, laterally loaded piles/sheet-piles, and long retaining walls is also included. engineers engaged in design of beams, strips, circular plates, circular-cylindrical tanks and silos. Postgraduate students and researchers working in the soil-structure interaction area should also find the book-software package of great value.
