Plastic Limit Analysis of Arch Dams
This paper applies the lower- and the Upper- bound theorems of the plasticity theory to arch dams, according to different forms of discretization for dam, two methods, namely the structural...

Application of PC Graphics, CADD, and Solid Modeling Techniques to 3-D Structural Stability of Concrete Monolithic Structures
A computer program for computing 3-D overturning and sliding stability (3DSAD) of concrete monolithic structures has been written and is widely used. This paper describes recent advances...

On the Usage of AutoCAD as a User-Interface for a Finite-Element-Program
This paper describes the approach used by the author to take AutoCAD as a user-interface for an existing Finite-Element-package. Some principles concerning database management are discussed,...

Computer-Aided Guyed Tower Analysis for the Rehabilitation of TTI Tower, Baltimore
A large guyed television tower owned by Television Tower Inc. of Baltimore is currently being analyzed in order to evaluate the capacity of the tower to support additional broadcasting...

Total Quality Management for Information Technology
Recently, there has been an increased awareness in the AEC firms toward Total Quality Management (TQM). Many AEC firms and the public sector started to look seriously at TQM. The reason...

Use of Construction Simulation in Claims Analysis
The increasing complexity of today's construction projects has led to considerable progress in developing sophisticated simulation-based methods and tools for the analysis and planning...

Order of Magnitude Reasoning for Qualitative Matrix Structural Analysis
Several computational schemes have recently been proposed to adapt Qualitative Reasoning for Structural Engineering applications. One current methodology. Qualitative Matrix Analysis (QMA),...

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...

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...

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,...

Artificial Neural Networks and Knowledge-Based Systems: Complementary AI Techniques for Civil Engineering
This paper considers the feasibility of integrating Artificial Neural Networks (ANNs) and Knowledge-Based Systems (KBSs) to solve civil engineering problems. KBSs are superior at representing...

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,...

Development of Differential Growth Method for Automated Vehicle Recognition
The purpose of this study is to improve a system which enables automatic recognition of vehicles from video images using image processing system. Basic methodology is a subtracting operation...

An Application of Fuzzy Set Theory to Preference Analysis in Bus Route Choices
One of the difficulties in applying fuzzy set theory to the real situation is how to determine membership functions. In this study, a questionnaire survey was conducted to assess bus riders'...

Classifying Constructability Information
Integration of constructability information in the early stages of a project is known to provide significant savings opportunities for cost and schedule. One critical part of such a program...

The Use of Numerical Rule Processors in Engineering Calculations
A Numerical Rule Processor uses a declarative approach to the processing of engineering calculations. The rules which link the parameters are set out in a separate rule base and the order...

Optimal Processor Mapping for Massively Parallel Finite Element Computations
The exploitation of massively parallel computer for finite element analysis requires efficient usage of processors as well fast speed. For example, the efficiency of a parallel matrix...
