F. E. Everett Turnpike: An Application of MOSS
MOSS surface modeling software is being used successfully by Fay, Spofford & Thorndike, Inc., on a major project for the New Hampshire Department of Transportation to make improvements...
The Application of AI in Highway CAD System
In a conventional CAD System, the process for solving a certain particular engineering problem is fixed stationary in the program. As a result, the program is often modified to fit different...
The 3D Approach to Design
Designing directly in three dimensions, including integrated analysis and information flow, is a powerful way to enhance civil engineering capabilities. Yet, relatively few have taken...
Designing in Three Dimensions for Manufacturing Facilities
Du Pont Engineering is using Three-Dimensional Design for the design of our manufacturing facilities. Our 3D design system was used on several projects in 1992, and full implementation...
Object Oriented Modeling of Structural Systems
Computational engineering in structural design is no longer restricted to numerical approaches. Increasingly, also non-numerical, in particular, cognitive problems can be implemented into...
Object-Oriented Modelling for Concrete Structures
The use of computers for the design process has reached wide acceptance. The use is developed in several fields such as CAD, CAM or programs for design of structural elements. Recent work...
Object-Oriented Data Exchange for the Integration of Design Processes in Structural Engineering
The computer integration of tasks, activities, tools, user and data exchange interfaces, management of knowledge etc. requires a new approach by object-oriented modeling in civil engineering....
Computing with Objects: What Does Industry Hope to Gain from it
Although the need for an integration of engineering tasks has been stressed for a long time, the success that we see in this regard is very limited. We believe that there is justified...
A Model to Quantify Work Space Availability for Space?Contrained Scheduling Within a CAD Environment
In any given process work area, a task or activity requires a specific amount of space for its execution. This required space must be accommodate by the physical space of the work area...
A CAD-Based Construction Simulation Tool Kit for Construction Planning
Current planning and scheduling techniques place considerable reliance on the planners judgement, imagination and intuition. The result of such techniques is typically lengthy text reports...
CAD Applications for Material Handling in the Construction Environment
Research at Va. Tech in the area of dynamic behavior modeling and crane damping have been undertaken. The dynamic behavior modeling capability has been designed to us 3-D CAD models and...
Knowledge and Information Processing with Drawing Objects in Construction Phase
Knowledge processing by CAD systems poses challenging problems for the efficient integration of design and construction processes. While CAD systems have been applied to various phases...
Comprehensive Site Monitoring Through Model Based Reasoning
The authors of this paper have developed a computer object oriented intelligent construction site modeler which is dynamically linked to a 3D CAD system. Model Based Reasoning is used...
Finite Element Analysis and Design of Bridges with Applicatrons of ICAD
This paper describes applications of client-server models, interprocess communications (IPC), and concepts of intelligent CAD (ICAD) to the interactive design and analysis of highway bridge...
Effect of the Periodic Secondary Irregularity on the Dynamic Behaviour of Railway Bridge-Vehicle System
The deformation and vibration of bridge will be developed due to the moving vehicles, especially for railway bridge. The dynamic deflections in the points under each wheel are called secondary...
Finite Element Representation of Approach Slabs
Approaches to bridges are designed to provide a smooth and safe transition from the highway pavement to the bridge deck and back to the highway pavement. Generally this transition area,...
Grillage Analogy for Multigirder Bridges
Grillage analogy is a method frequently used to simulate the structural response of highway bridges with reinforced concrete deck and steel girders. This approach saves substantial efforts...
A New Approach for Road Network and Bridge Planning
Road networks usually include a large number of bridges and tunnels. The locations of these bridges and tunnels are decided by the road planner during the design of the road alignment...
Managing AutoCAD and Intergraph MicroStation Systems
The reality today is that Computer Aided Design information is being transferred from one CAD system to another. More often, sharing CAD information among the design team requires multiple...
