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...
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
This paper presents current research and develop on process modeling that can support cooperative planning among designer, engineer, project planner and project manager in industrialized...
Characteristics of the US Highway Bridge Population
Characteristics of US highway bridges are summarized, and conditions of national, regional, and state bridges are analyzed with respect to structural deficiency. The overall patterns in...
Empirical Performance Comparison for Symbolic and Subsymbolic Learning Systems
The paper gives a description of a comparative study of two learning systems based on symbolic and subsymbolic learning. The two systems' performance was analyzed using the overall empirical...
