Written for engineers without a background in seismic design. Provides design standards and parameters, explaining how to interpret and apply them. Examines and recommends procedures to accommodate the enormous forces and variations in effects common to major earthquakes. Covers practical aspects of soil behavior and structural and foundation design. Gives tips on special construction situations: foundations, dams and retaining walls, strengthening existing structures and construction over active faults.

Radiography, the use of penetrating radiation to produce shadow images of the internal structure of materials, has been with us since Roentgen made his discovery of x rays in 1895. However, applications of radiography in the earth sciences and in the related field of soils engineering have, until recent ly, been slow to develop. Bruhl reported optimistically on applications in paleontology as early as 1896 and there have been additional reports through the years. However, very few paleontologists adopted the method and the significant literature is relatively restricted. In soil mechanics,...
