A Constraint-Based Composites Design Advisor
Most engineering problems, because they involve mathematical relations (constraints) on real valued quantities (objects), can be reduced to constraint networks. The authors speculate that...

A Knowledge-Based System for the Damage Assessment of Timber Trusses
A knowledge-based system for the maintenance of over two hundred timber Warren truss buildings is being developed at the Royal Military College of Canada by the Knowledge-Based Expert...

Quality Control and Constructability of Slabs on Grade With Expert Systems
Constructability and quality control problems associated with the construction of slabs on grade are many. They vary from problems associated with cracking, scaling, dusting and spalling,...

Accurate and Efficient Element for Analysis of Concrete Structures
Reinforcement details in concrete structures are inherently complex. Therefore, the treatment of reinforcements is one of the most influential factors in the accuracy and efficiency of...

Crack and Contact Problems in Masonry Arch Bridges
A two-dimensional finite element program has been developed to predict the load carrying capacity of masonry arch bridges with different structural defects such as missing bricks and tangential...

Study of a Computer System for Evaluation of Bearing Wall Stresses in Structural Planning ? Reasoning by Neural Network
This report proposes a reasoning system for bearing shear wall stresses in the ultimate state by using geometrical data of buildings and shear walls at the initial stage of aseismic structural...

Analysis of Sequential Route Choice Under ATIS
An experiment to collect sequential route choice data under the influence of an Advanced Traveller Information System (ATIS) was performed using a PC-based interactive simulation. The...

User-Friendly Simulation Model for Traffic Networks with ATIS/ATMS
Implementation of ATIS (Advanced Traffic Information Systems) and/or ATMS (Advanced Traffic Management Systems) are proceeding in many cities around the world, but only very few frameworks...

The DWR Delta Graphical User Interface
Previously, most modeling development has been in the area of algorithms, with relatively little effort spent on conveying the results of models. A graphical user interface to a database...

Building Object-Oriented Systems for Diagnostic Problems in Civil Engineering
In recent years, rehabilitation and renovation of existing buildings and roads have grown to occupy a significant share of all civil engineering projects. Proper timing of rehabilitative...

Reliability-Based Assessment of Navigation Structures
In 1989, the Director of Civil Works, U.S. Army Corps of Engineers (HQUSACE), requested regional assessments of the future modernization needs of Corps Divisions with significant inland...

Design and Construction Support with Object-Oriented Database Kernel Systems
The heterogeneity of tools and their data models in civil engineering is a well known problem. Next generation database technology seeks to offer solutions for the integration of the design...

An OOP Model for Scheduling of Repetitive Projects
Repetitive projects are characterized by the presence of large number of repetitive activities, along with a number of non-repetitive activities. Each of thee two types of activities requires...

Real-Time Position Measurement Integrated with CAD-CAE and Related Data Structure Issues
The Civil Engineering Research Foundation (CERF), Bechtel Corp. (Bechtel), Jacobus Technology, Inc (Jacobus), and Spatial Positioning Systems,Inc. (SPSi) have formed the Consortium for...

An Application of Neural Networks to Hysteretic Modeling of Steel Structures
This paper describes an application of the neural networks to realistic hysteretic modeling. The neural networks learn from sample data (training cases) and make predictions for new cases....

Computer Assisted Conceptual Structural Design of Steel Buildings
The design quality of a building is mostly determined during the conceptual design stage. Computers, however, have not been used effectively to handle the conceptual design of building...

Three-Dimensional Nonlinear Analysis of a Wooden Structure with Base Subsidence
A heavy rain caused a famous Chinese ancient wooden structure to suffer serious base subsidence. In order to deal with the base subsidence of the valuable structure, a joggle model and...

Numerical Analysis of Membrane Action in Hollow Core Floors
The emphasis of the investigation is on the diaphragm action of precast floor structures. In order to improve existing manual calculation methods a parameter study has been carried out...

Decision Methods for Selecting Earth Retaining Structures
The Bridge Branch of the Colorado Department of Transportation (CDOT) has organized the framework of a formal decision process for retaining wall selection. The process facilitates implementation...

A Model and Realization of Intelligence CAD System
