Formal Specification of AEC Product Models
This paper illustrates the use of equational specifications in developing product data models. This approach enables a precise and abstract description of products, where both syntactic...
Knowledge Issues in Modeling
This paper aims at stressing the importance of the goal of modeling in identifying the underlying bodies of knowledge. It briefly describes the progression in complexity of modeling and...
Issues and Experiences in Developing Shared Object Models
Effective communication of data among work processes is key to the successful operation of an Architecture, Engineering, Construction (AEC) project. However, communicating this data is...
Multimedia Technologies for Civil and Construction Engineering Professional Practice
Multimedia can be classified as any experience or application that uses two or more media to convey a message or achieve a given purpose. Some of the main types of possible applications...
Strengthening the Design/Construction Interface Using Electronic Imaging, Document Management and Work Flow Technologies
The paper describes a conceptual approach for the implementation of document imaging systems as a mechanism for strengthening the design/construction interface. The paper discusses some...
Progression of Computer Applications in Water Supply and Distribution Systems
Over the last two decades, computer applications in water supply and distribution systems have advanced rapidly from the stand-alone applications in system modeling to the integrated platform...
Development of an Expert System for Daily Drought Monitoring
A daily drought monitoring system was developed using the Clips Expert System software package. It consists of four components: (1) The knowledge base that contains rules in the form of...
A program for the Analysis of Pile Load Tests
The load capacity of piles are routinely determined from full scale pile load tests under actual field conditions. Several empirical methods were proposed for the analysis of field load/settlement...
Computer Modelling of Comminuting Granular Media
Using generalized continuum mechanics, generalized damage theories for granular materials in comminution processes are proposed. The generalization is accomplished by treating the average...
The Application of Artificial Neural Networks to Civil Engineering
Recently, there has been much interest in the application of artificial neural networks (ANNs) to civil engineering problems. Most applications, however, have been limited to the use of...
Bridge Rating Using Influence Surface for Curved Bridge Structures
A fairly sizeable number of curved steel bridges in Louisiana need to be rated and influence lines required to be stored. A methodology is developed and rating procedures are established....
Computer Analysis of Continuous P/C Highway Bridge Girders with Variable Depth
A computational procedure and associated computer program were developed for the analysis and design of P/C continuous beams with variable depth. Using this program, continuous girders...
An Assessment of the Joint Factor as Used in the Modified MEXE Method
The finite element method has been used to examine the joint factor in the modified MEXE method which is documented in the publications (BD21/93 and BA16/93) by the Department of Transport...
Impulse Effect on Redundancy of a Tied-Arch Bridge
This paper studies the redundancy of a tied-arch bridge using a 3-dimensional finite element computer model. By using static incremental loading simulation, a tied-arch bridge designed...
Calibration of a Highway Traffic Assignment Model for the Manhattan Central Business District
This paper describes the application of a traffic assignment model, specifically the TRANPLAN model, in New York City together with the methodologies and the satellite programs that were...
A Speed Prediction Model for New Zealand Highways
This paper outlines a limiting speed model using probabilistic techniques to simulate the different types of vehicles and their performance along a two-lane rural highway. The road to...
An Integrated Computer Model for Project Schedule Updating
Current schedule updating techniques rely mainly on field reports to specify completed work. Information provided in these reports are then manually summarized, analyzed, and input to...
Overlaying Digital Images with 3-D CAD to Document as Built Construction
A persistent problem in construction has been documenting changes which occur in the field and preparing as-built drawings. The accuracy and completeness of field measurements is often...
Graphic Visualization for Planning Heavy Lifts
The application of graphical visualization to construction can serve a wide variety of objectives and offers many significant benefits. Heavy lifts are an important component of industrial...
Building Product Model, A First Brick in Computer Integrated Construction
This paper describes the development of a product model as a basis for an information system. This new approach is based on modelling functions of building units rather than physical entities...
