dc.description.abstractThis report documents the Three-Dimensional (3-D) Stability Analysis/Design (3DSAD) computer program. Both general purpose and specific modules are discussed. Currently, the four general modules are Geometry, Loads, Analysis, and Free-Body. The General Geometry Module defines geometry and performs volume, weight, and centroid computations. It also utilizes interactive computer graphics. The General Loads Module computes forces and moments for the defined loads on a general 3-D structure using pressure volumes, surface loads, and point loads. It also allows the definition of different load cases. The General Analysis Module performs overturning, bearing, and sliding computations for any planar or near-planar base. The Free-Body Module “clips” the structure and loads by an arbitrary plane to produce a “free body” so that computations can be performed on the new part. In addition to the general capabilities that are useful for any 3-D structure, 3DSAD provides for simplified geometry and loads input, along with criteria check and design modules, for dams (CDAMS). Finally, examples of locks done by practicing engineers are provided.en_US
