Publisher Summary This chapter presents the concluding remarks of all the topics covered in the book. Starting from scratch, a treatise is written developing the one-dimensional strength-of-materials theory of conical bars and beams called cones that are applied to practical foundation vibration analyses. Confidence in cones is gained because the procedure to analyze foundations is the same as routinely used in structural analysis, and a systematic evaluation for a wide range of actual sites demonstrates sufficient engineering accuracy. A short computer program written in MATLAB forms an integral part of the book, and a user-friendly executable program is also provided. Using the cone models leads to some loss of precision compared to applying the rigorous methods. The achieved accuracy using cone models is more than sufficient. It cannot be the aim of the engineer to calculate the complex reality as closely as possible, as this is not required for a safe and economical design. The accuracy is limited anyway because of the many uncertainties that cannot be eliminated such as the wide scatter of the dynamic material properties of the soil.
