Title: Implementation of the Tri-Service Workspace for AutoCAD users
Authors: Shaw, Doris S.; Ort, Sara E.; Millburg, Katherine R.; Lagrou, Jerry M.
Abstract: The U.S. Army Corps of Engineers has undertaken the task of implementing a workspace for AutoCAD that will satisfy the functional requirements found in a 1996 user study. The major goal is to provide an environment to facilitate the production of computer-aided design and drafting (CADD) documents that comply with the Tri-Service graphic standards. The workspace must ensure that users are updated as standards change, and it must work concurrently with existing and newly created CADD software tools. It is also important to provide an intuitive, discipline-specific interface for those who do not choose to use add-on software. The workspace should support the user's needs for checking compliance with the standards and for updating nonstandard design files. The program has been designed so that the necessary updating and compatibility may be provided with as little maintenance cost as possible.

Title: State of the art on expert systems applications in design, construction and maintenance of structures
Authors: Arockiasamy, M.; Sunghoon, Lee
Abstract: A comprehensive review of knowledge-based expert system applications to structural design, design standards, and construction planning for typical structures is presented in this report. The example systems reviewed in structural design include buildings, retaining walls, bridges and frameworks. Earlier work in design standards contributed to improvements in the representation and organization, analysis, and use of standards. The review includes typical representative expert system applications in construction engineering and management, soil exploration, site layout, real-time construction operations, construction planning and scheduling, etc.

Title: Comparison of barge impact experimental and finite element results for the lower miter gate of Lock and Dam 26
Authors: Will, Kenneth M., 1947-
Abstract: A finite element analysis of barge impact on the lower miter gate of Lock and Dam 26 is presented. The response of the structure was assumed to be linear and the barge impact was modeled as an equivalent static load. The analysis was originally intended to aid in planning full scale barge impact tests at Lock and Dam 26. Due to contract delays and the scheduled demolition of the gate, the analysis was not completed prior to testing. The results of the finite element analysis are presented and compared with the full scale test results.

Title: Optimization of steel pile foundations using optimality criteria
Authors: Hoback, Alan S.; Truman, Kevin Z.
Abstract: The layout of steel piles is optimized to find the least weight structure. The pile cross-sections and the pile orientations (batters) are varied using optimality criteria. The handling of topological variables by the optimality criteria approach is thoroughly discussed. Several examples are given. One example is a retaining wall for which a two-dimensional pile layout can be used to represent a segment of the wall. Another example is a control tower. Four other examples are dam structures.
