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...

Exchanging Layout and Schedule Data in a Real-Time Distributed Environment
Unpredictable site conditions and unforeseen changes in construction work may result in inefficiencies due to a shortage of work space and difficult access to critical areas on site. This...

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
This paper describes a model of intelligent CAD system for arch dams and it's characters on intelligence, structure and application. The paper describes the practice method from the content,...

Framework for an Automated Quality Control System in Working Drawing Production
CAD use for the planning, design, construction and operation of buildings continues to expand at a rapid pace throughout the industry. While CAD applications include a variety of uses...

Construction and Maintenance Decisions for Multi-Unit Deteriorating Facilities
Facilities that deteriorate over time and use can require maintenance or replacement. Selecting among replacement and maintenance alternatives for large systems of deteriorating facilities...

Benefit-Cost Analysis for Optimal Budget Allocation to Bridges
The funding available for bridge improvements in the United States has been insufficient for many years. The limited budgets granted have generally been allocated based on Sufficiency...

NCHRP Project 12-28(2)A Bridge Management System Software
This paper describes the various features of the bridge management system being developed by NET Corporation as part of a project funded by the National Cooperative Highway Research Program...

Bridge Management System Implementation at CALTRANS
Development of a new generation of Bridge Management System (BMS) capabilities has been a high priority for CALTRANS for the past four years. Although the Department has had a bridge inventory...

Intelligent Optimal CAD (IOCAD) for Arch Dams
The artificial intelligence, optimization methods and CAD techniques are mixed to develop an integrated system for design of arch dams. It includes a knowledge base, a data base, a stress...

Knowledge-Based Creation of an Architectural 3-D Model from 2-D Drawings
This study is an extension of an earlier work on creating a 3-D model from 2-D drawings. The objective of this current work is to explore the issues involved in creating a prototype knowledge-based...

Masonry Cladding, an Expert System for Distress Diagnosis
An expert system for masonry cladding failure diagnosis was developed. The system provides a heuristic procedure for diagnosing the most probable causes of cladding distresses and failure...

CAD System for Structural Aesthetics of Bridge Form
An exploratory design process for aesthetic bridge structure is proposed in this paper through developing a prototype of comprehensive CAD system. This process is conceived not only for...

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...
