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...
A Computational Algorithm for Analysis of Rectangular Footings Under Partial Contact with Soil
This paper describes a method to determine the distribution of base pressures under a rectangular footing experiencing partial contact of the footing with soil. Assuming the footing to...
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...
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...
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...
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...
Transactional Support for Concurrent Finite Element Analysis & Design
The finite element (FE) analysis and design process deals with large amounts of complex engineering data. Although sophisticated techniques have been developed for computer-aided FE analysis,...
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...
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...
Analysis of Port Allen Lock in Elastic-Plastic Soil Medium
Incremental finite element analyses using Drucker-Prager plasticity model are applied to study the interaction of Port Allen Lock with its surrounding soil. The analyses not only consider...
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...
The Development of an Expert System Used in Preliminary Design of Concrete Bridges
The importance of the selection of the best design on the one hand and the available knowledge, on the other during the preliminary design process asks after a different kind of software...
Time-related Deflections of Cantilever Bridges
Many prestressed concrete bridges with spans between 100 and 160 m have been built in the Netherlands. The method of construction is the so-called in situ free cantilever construction....
Automated Design of 3-D Highway Sign Bridge Structures
A PC-based computer analysis/design program for 3-D Sign Bridge Structures including Pre- and Post-processor has been developed. The analysis of thirty different types of sign support...
Intelligent Construction Planning
The intelligent construction planning is a stage of automated building realization process. The building is defined in the design stage by its spaces and functional systems. The automated...
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...
Object-Oriented Process Modeling to Support Cooperative Planning in Industrialized Building Construction Project
