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...

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...

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....

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...

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...

Developments to the IRMA Model of AEC Projects
The rapidly advancing fields of information technologies (IT) for AEC and computer-integrated construction (CIC) rely on the ability to represent and exchange information about AEC projects...

Information Modeling and Applications
The objective of this paper is to describe events and findings in the development of a comprehensive information architecture for a building. The information architecture has a goal of...

Design and Implementation of a Database for Seismic Evaluation of Structures
The seismic evaluation of large structures, such as bridges, requires a comprehensive framework for managing the data. An evaluation typically involves the dynamic analysis of a number...

Deductive Databases in Engineering
Many engineering systems can be modeled in terms of objects and relationships among objects. As generalized relational databases, deductive databases provide a suitable tool for representing...

Utilizing Mathcad for Hydraulic Design of Stormwater Pump Stations
This paper describes how the software Mathcad was used for hydraulic design of three pump stations (i.e. select pumps and size forcemains). The pump stations are part of a complete stormwater...

Hybrid Finite Element/Discrete Element Model for Large Deformation Geotechnical Engineering Problems
New hybrid finite element/discrete element computational code was developed for large deformation geotechnical engineering problems with granular materials. The code uses the finite element...

Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...

A Machine Learning Decision Support System for Collaborative Design
The research described in this paper is motivated by the complexity surrounding the development of decision support systems (DSSs) for collaborative design processes. If one realizes that...

Conceptual Models of Product, Project and Document Data; Essential Ingredients of CIC
A number of current on-going national and international standardization efforts which develop standards for information structures in construction are reviewed in the paper. These concern...

Prototype Applications of Integrated Data Models in Construction
Problems in computer integrated construction arises not only from a lack of technically proficient models of data integration but also its lack of experience and understanding of how such...
