This book was released on 1998 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: This 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.

Available in PDF, EPUB and Kindle. Book excerpt: This report describes the General Analysis Module of the three-dimensional stability analysis/design (3DSAD) program. The module performs overturning, bearing (base pressure), and sliding computations for a structure. The report presents both a user's guide and a theoretical discussion for the module.

Available in PDF, EPUB and Kindle. Book excerpt: This module of the three-dimensional stability analysis/design program (3DSAD) enables the engineer to describe the geometry of a three-dimensional structure, to interactively plot the desired structure, and then to obtain volume, weight, and centroid information for the structure. The general ways in which geometry is described are (a) two-dimensional cross sections extended in the third dimension, (b) eight-node brick elements, and (c) clusters of planar polygonal patches. Curved segments can be either circular, elliptical, or quadratic. Hidden lines in a view can be either deleted or dashed. (Author).

This book was released on 1989 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: 3DSAD (Three Dimensional Stability Analysis Design) performs 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. The Free-Body Module is a utility written to provide the user with the ability to perform an analysis of a structure at elevations or cross sections other than its base. It produces a free body containing a new definition of geometry and loads, by allowing the user the ability to clip the structure with a single plane or multiple planes. Output consists of a file containing the clipped geometry and loads data for use with the General Geometry or General Loads Module and a base file used with the forces and moments computed from the first data file to perform an analysis with the General Analysis Module. The General Analysis Module is used to produce a base pressure computation that is an approximation of the internal stresses in the structure at the clipping plane. Keywords: Computer-aided design, Free-body computation, Interactive graphics, Stress analysis, Structural stability, Three-dimensional graphics.

Tracy and published by . This book was released on 1987 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: This module of the three dimensional (3-D) stability analysis/design program (3DSAD) enables the engineer to describe the geometry of the 3-D structure, to interactively plot the desired structure, and then to obtain volume, weight, and centroid information for the structure. The general ways in which geometry is described are (a) two dimensional cross sections extended in the third dimension, (b) eight node brick elements, and (c) clusters of planar polygonal and bicubic patches. Curved segments can be circular, elliptical, or quadratic when using blocks and cubic when using patches. Objects can be copied, translated, rotated, or reflected about an axis as well. An arbitrary clipping plane can also be passed through the geometry. Keywords: Computer aided design; Structural analysis; Structural design.

Book excerpt: Computer program TWDA (T-wall design/analysis) is a user-oriented conversationally interactive, modular time-sharing program system for computer-aided structural design of inverted-T retaining walls and floodwalls founded on earth or rock. Its essential characteristics include: (a) List-directed input with prompting available on request or as shown to be needed. Data lists may be entered interactively or in a data file. (b) Design for minimum cost including excavation, backfill, slab concrete, and stem concrete, with inputted unit costs. Default is to design for minimum concrete volume. (c) Multiple soils strata may be used as existing and/or backfill earth. Either Coulomb's equation or trail wedges may be used to get active earth pressures. (d) Multiple slopes may be used to model existing and/or finished grade surfaces. (e) Time-sharing printout is limited to the minimum needed by the user to make his design decisions. A full analysis report is available in an optional output file that may be listed on any terminal. (f) The program is structured to permit easy updating as criteria change. (g) Up to 10 load cases may be used. The user does not need to reenter any data by hand into subsequent runs. (h) The 1977 edition of ACI code 318 is used. Default procedures conform to the Corps of Engineers' Engineer Manuals in effect in 1980. The user may, however, direct the program to change many of the standard procedures as needed. (Author).
