Implementing Qualitative Reasoning for Structural Design Using Constraint Propagation
All designs begin with qualitative reasoning and therefore, this activity has an important influence upon subsequent quantitative stages. In structural design, qualitative reasoning starts...
Reducing Ambiguity in Qualitative Reasoning
Qualitative reasoning derives the behavior of a physical system using a representation of the fundamental principles for the domain. In qualitative reasoning parameters are mapped into...
Integrated Slab Design Automation System Using Knowledge-based Approach
There has been a strong trend towards the integration of computer aided design and engineering during recent years. But all the systems can not provide the completely integrated functions,...
Interference Detection with 3-D Computer Models
Interferences between building components during construction is an inherent byproduct of multiple disciplines designing their components separately. Manual solution techniques for detecting...
Three-Dimensional FEM Analysis with Graphical Interface
We have developed a Three-Dimensional FEM Program with an extended graphical interface aimed at analyzing buildings. This program is linked with our CAD system, which can easily produce...
A Computational Method for Acquiring Response and Ground Motion from Accelerogram on the Base of Structure
This paper describes computational formulation of vibratory equations for acquiring response and input ground motion from accelerogram on the base of long structure with flexible slab....
Editing Existing Paper Drawings
In the last five years, developments in creating and managing engineering drawings completely, within a computer environment, have been phenomenal. Computer Aided Design continues to make...
Modular Software for Editing Paper Drawings
Revising, tracking and storing large format engineering drawings has always been an expensive and complex problem for large industries. The management problem became much more complex...
Maintaining Engineering Drawings in the '90s
With the technologies available today, it is possible to begin a scanning system at a rather small or limited scale - and still realize a quantifiable return on investment. In the 90's,...
Your Paper Drawings in the World of Organized Information
A comprehensive discussion of available hybrid raster-vector techniques and tools is provided. The author uses a sample project to clarify the most common misjudgements that result from...
Information Technology: Panacea or Poison?
Consulting engineering is entering a period of dramatic change which will provide opportunities and threats. Pressure on fee levels and changing markets are necessitating a greater emphasis...
A Comparison of Two AI Based Design Systems
Two applications of Civil Engineering based, AI systems are described. Although both systems are intended as design aids they have substantially different structures and methods of achieving...

Graphical Resource-Based Object-Oriented Simulation for Construction Process Planning
Simulation is a powerful tool for construction process design and optimization. The results of a simulation provide detailed process information, such as resource utilization and idleness,...
A Numerical Procedure to Compute Bearing Capacity of Shallow Foundations
A simple numerical procedure of calculation of bearing capacity of shallow foundation is proposed. This procedure employs the Terzaghi-Prandtl model of general shear failure. In this paper,...
Application of Spencer's Method for Slope Stability Analysis
For slope stability analysis with general, arbitrarily shaped failure surfaces, the Spencer's method has been found to provide a reasonably accurate result. This method satisfies both...
Learning Engineering: An Outline
The paper presents an outline of learning engineering, which is a new subarea of knowledge engineering dealing with the methodological aspects of using learning systems in knowledge acquisition....
Adapting Conceptual Clustering for Preliminary Structural Design
The use of conceptual clustering for knowledge acquisition can facilitate the development of a knowledge base in a domain where little formalized knowledge is really available. The limitations...
Competitive Advantage of Using Computers in Structural Design
More and more structural analysis and design work is done using computers. The trend will continue because the software is becoming more powerful and the cost of computers is falling....
Computer Aided Experiments for Truss Structures
It is quite difficult to investigate structural mechanical properties by full scaled structure experiments. Consequently, an experiment using a reduced scale model is generally performed....
