Hyper-Geodesic Structures: Excerpts from a Visual Catalog
A class of hyper-geodesic surface structures is presented. The surfaces of known polygons, polyhedra, plane and space tessellations, higher dimensional polytopes can be subdivided into...

Morphology of Reciprocal Frame Three-Dimensional Grillage Structures
This paper is an introduction to the morphology of structures using the Reciprocal Frame (also known as Mandala Dach in Germany) which is a patented three-dimensional beam grillage structural...

Recent Advances in Engineering Design Methodologies
The paper illustrates the mode of operation of the Engineering Design Research Center (EDRC) at Carnegie Mellon University by describing a number of EDRC projects related to structural...

The Future of the Past: Historic Preservation at the Metropolitan Washington Airports
The historic significance and unique architectural character of Washington National and Washington Dulles International Airports have presented the Metropolitan Washington Airports Authority...

Circle Integration
Based on the results of proof-of-concept experiments, we propose that an integrated suite of software tools can support both automation and integration of several components of AEC design...

Startplan: Producing Schedule Templates Using IRMA
The Information Reference Model for AEC (IRMA) is a generic information modeling standard to support computer-integrated construction (CIC). Although IRMA is still in a conceptual stage,...

Construction Problem Solving in a Cooperative Distributed Agent Environment
This paper outlines the research being undertaken by the authors to determine how experts develop solutions to construction problems in a cooperative distributed agent environment which...

Selection of Earth Retention Systems Using Expert System
The development of the selection module in a knowledge-based expert system REtaining STructure EXpert (RESTEX) for automated selection, design and analysis of earth retention systems is...

Scaling Up is Hard to Do: Experiences in Preparing a Case-Based Design Aid Prototype for Field Trial
We seek to improve the conceptual design process for complex artifacts such as buildings by offering designers access, through an on-line hypermedia library, to documentation and evaluations...

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...

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...

A Decision Support System for the Expansion of International Operations of A/E/C Firms
The changing trend of the construction industry will require A/E/C firms to consider expanding operations in the international construction market arena. This paper presents a conceptual...

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...

A Framework for Collaborative Distributed Facility Engineering
A framework for collaborative distributed facility engineering is presented. This framework is an extension of an agent-based framework for facility design software integration. The focal...

Constraint Management on Distributed AEC Configurations
Architecture, Engineering and Construction (AEC) design processes involve the participation of many designers who may be working independently in geographically distinct locations. We...

Information, Global-Style
The quality, timeliness and accuracy of information can give an international architectural, engineering and consulting firm a distinct competitive advantage, and the wrong system can...

Investigation of Full-Scale Performance of Structures?Research Potentials
It is well known that actual, or true, behavior of completed structures does not necessarily conform to often simplified analysis predictions. This may be due to any of several reasons...

Agent-Based Technology for Facility Design Software Integration
The application of a novel technology called Agent-Based Software Engineering to facility design software integration is presented. The technology is founded on the notion of design agents...
