Expert Opinions and Expert Systems
The inference mechanism in most current expert (rule-based production) systems is based on exact matching of the antecedent or consequent of a rule with a fact or hypothesis. The rule...

Applications of Artificial Intelligence in Preliminary Structural Design
The field of Artificial Intelligence (AI) deals with the problems of modeling human intelligence. The application of AI to structural engineering has been limited, but potential applications...

Proposed Operation of an Expert System for Analyzing Construction Project Risks
The principal problem for the construction project manager is selecting the most effective response when project progress deviates undesirably from targeted objectives. Optimally, the...

Broke2: A Program for Broken Wire Analysis
A computer program to study the dynamic behavior of an electric transmission line system when wires suddenly break has been developed by the authors. All three of the line elements: the...

Response of Eccentrically Braced Tall Buildings
The inelastic dynamic response aspects of tall steel buildings with eccentric K-bracing and eccentric X-bracing systems are examined, when subjected to factored El-Centro and computer...

Interactive Design of Reinforced Concrete Foundations
A new, highly graphical foundation design program, FOUNDATION-3D, provides the designer with a variety of easy to use foundation design tools in a flexible interactive environment. It...

Experience With Workstation-Based Design of Steel Structures
An example is presented of an interactive graphical structural analysis and design system suitable for individual-user workstations. The experience of a corporate engineering services...

The Electric Power Research Institute's TLWorkstation?
The initial version of the Electric Power Research Institute's TLworkstation software system is described. The factors influencing the software design and the programming...

Nonlinear Structural Analysis on an Engineering Workstation
The objective of this paper is to demonstrate the feasibility of solving nonlinear structural analysis problems on a desktop engineering workstation. The paper summarizes the main features...

Self-Adapting CAD Software
An approach for enhancing CAD and other interactive software is described. The goals of the approach are bifold, to customize complex programs which employ computer graphics, and to improve...

An Interactive Shell for Batch Processors
Many programs have been and are currently being developed in which the input data files or associated databases must be developed independently of the main program. This paper describes...

Structural and Architectural Maintenance Management by Micro-computer
When a new Senior Vice-President for University College, the nonmedical portion of the University of Alabama at Birmingham, was appointed in 1984, one of the problems encountered by the...

Seismic Structural Optimization and Computer Programs
A generic system has been developed for the geometric design of highway retaining walls. Merging the three-dimensional coordinate geometry capabilities of the roadway design system (RDS)...

Analysis and Optimum Design of Nondeterministic Structures under Random Loads
The importance of analyzing and designing structural systems by using a reliability-based approach is emphasized, including system safety requirements with regard to both serviceability...

Structural Design Optimization of Nonlinear Response With Adina
Procedures for sensitivity analysis and optimization of nonlinear structural systems with the computer program ADINA are described. Formulation of the structural optimization problem and...

Animated Response of Dynamic Systems
Understanding how a simple structural system responds to a dynamically applied load is a difficult concept for most students to grasp. The fundamental mathematical theory of this behavior...

The Software Implications of Supercomputer Architecture
A simple look at computer architecture from a computational (and hence user) perspective is observed. A relation between computer architecture and software development is explored. Today's...

Attached Scientific Computers in Structural Analysis
The design and analysis process is explored in terms of its requirements for user decision-making and interaction. This is presented as a three-phase procedure: (1) the engineer developing...

Reflections on the Impact of Computer Science on Engineering
Over the past several decades, the use of computers in engineering has grown significantly. Over this same time period, work in the relatively new discipline of Computer Science has impacted...

Tiedback Walls Untie Intersection
The intersection of Gallows Rd. and Arlington Blvd. in Virginia's Fairfax County required separation. Tiedback retaining walls, which required only 18 in. instead of the 18-22...
