Abstract:

Computer program 3DSAD does an overturning and sliding stability analysis for complex three-dimensional structures. Specific structure types and general shapes can be handled. General modules are geometry--to define, display, and compute mass properties loads--to define, display, and compute loads analysis--to perform a base analysis assuming a rigid body on an elastic foundation and free-body--to use clipping capability for a free-body analysis. Geometry is defined by two-dimensional cross sections swept or grown linearly or axisymmetrically in third dimension, eight-node brick finite elements, and clusters of planar faces and bicubic patches. Loads are computed by giving a direction to a volume defined in the General Geometry Module format, specifying a point load, and simplifying load commands wherever soil and water levels are specified. Geometry and loads may be displayed by color wire-frame, hidden line, or continuous tone plots, and load cases may be defined.
