CAD Instruction for Civil Engineering Students
Computer graphics and computer-aided drafting (CAD), as well as manual graphics and descriptive geometry, are successfully taught to civil engineering sophomores. The paper presents the...
Computer Aided Learning of System Reliability Assessment
Good education should foster an awareness of the probabilistic nature of the real world. Insensitivity to, or inability to acknowledge and analyze, uncertainties of this world can lead...
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...
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...
Applying Constraint Satisfaction Neural Networks to Multiple Views' Data Partitioning in Building Engineering
A typical building engineering process involves multiple project participants and several computer applications. These participants and applications have their own views of the underlying...
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...
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...
Non-linear Analysis of a Cable Stayed Bridge
A concrete single-pylon cable-stayed bridge has been analyzed to investigate the ultimate capacity. Two different methods were used to investigate the nonlinear behaviour. First, a simplified...
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...
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...
