    • Functional Analysis Using Partitioned Engineering Data Flow Model 

      D. H. Douglas Phan; H. Craig Howard (American Society of Civil Engineers, 1994)
      Functional analysis is important for developing information systems in facility engineering. In this paper, we propose the partitioned engineering data flow model (abbreviated PANDA), an extension of the data flow model ...

    • Bridge Planning Using GIS and Expert System Approach 

      Amin Hammad; Yoshito Itoh; Takayuki Nishido (American Society of Civil Engineers, 1993)
      In the planning process of a new road network, the planner should consider possible locations of bridges and tunnels. The selection of the best alignment imposes the need to investigate the effect of the location of each ...

    • Model‐Based Planning: Scaled‐Up Construction Application 

      Graham Winstanley; Michael A. Chacon; Raymond E. Levitt (American Society of Civil Engineers, 1993)
      Construction planning and scheduling is a complex process involving the design process, activity sequencing, resource allocation, and timing. The problems are compounded by the multidisciplinary nature of the architectur ...

    • DEM Aggregation and Smoothing Effects on Surface Runoff Modeling 

      Baxter E. Vieux (American Society of Civil Engineers, 1993)
      A digital elevation model (DEM) may be used in modeling direct surface runoff. Topographic variability affects the apparent slope and flow path length extracted from DEMS. Smoothing of the digital elevation data is a common ...

    • Knowledge Representation and Processing in Relational Data Base 

      Teresa M. Adams (American Society of Civil Engineers, 1993)
      This paper is a comparative study of the set operators in rule‐based production languages and relational query languages. This paper illustrates the use of structured query language (SQL) subselect conditions IN, NOT IN, ...

    • GIS Procedure for Developing Three‐Dimensional Subsurface Profile 

      Charles V. Camp; Michael Clay Brown (American Society of Civil Engineers, 1993)
      A geographic information system (GIS)‐based procedure for developing subsurface profiles from well‐log data is developed. The well‐log data base is constructed from a series of borehole geophysical logs. Interpretation of ...

    • Prototype Integrated Cost and Schedule Control System 

      Osama Y. Abudayyeh; William J. Rasdorf (American Society of Civil Engineers, 1993)
      Effective management of construction projects depends on good access to and control of data, especially data pertaining to cost‐ and schedule‐control functions. Long recognizing the need to integrate these interrelated ...

    • Spatial Data Models for Managing Subsurface Data 

      Teresa M. Adams; Agatha Y. S. Tang; Nancy Wiegand (American Society of Civil Engineers, 1993)
      Most geographic information system (GIS) software encodes topological relationships between spatial objects, such as neighborhood and inclusion, in node‐line‐polygon tables. However, some applications require semantic ...

    • HyperDocument Model for Design Standards Documentation 

      Nobuyoshi Yabuki; Kincho H. Law (American Society of Civil Engineers, 1993)
      The present paper describes a HyperDocument model for the documentation of design standards. The HyperDocument model consists of a document base and a navigation system. The document base contains the electronic documents ...

    • Building KBES for Diagnosing PC Pile with Artificial Neural Network 

      Yi‐Cherng Yeh; Yau‐Hwaug Kuo; Deh‐Shiu Hsu (American Society of Civil Engineers, 1993)
      Diagnosis of damage of prestressed concrete piles during driving is an important problem in foundation engineering. An effort to build an expert system for the problem is described in this paper. To overcome the bottleneck ...

    • Making Data Banks More Useful with Knowledge‐Embedded Data‐Base Systems 

      Chee‐Kiong Soh; Ai‐Kah Soh; Kum‐Yew Lai (American Society of Civil Engineers, 1993)
      The focus of the present paper is on the data‐knowledge integration problem, whereby data and knowledge can be made radically more useful within the same framework. Most tools for developing knowledge‐based systems do not ...

    • Expert System Based Training for Emergency Management 

      J. Sharit; S. Chen; D. ‐Y. M. Lin (American Society of Civil Engineers, 1993)
      Although expert systems are usually thought of as decision aids for human users, they may also serve as training aids for situations in which humans must make quick decisions and computer‐based decision aids would not be ...

    • Expert System for Optimum Design of Concrete Structures 

      R. Ramesh Reddy; Ashok Gupta; R. P. Singh (American Society of Civil Engineers, 1993)
      Optimization of concrete structures at the conceptual design stage has been based so far on informal methods. The designer would use his expertise, which is often heuristic, to find optimum solutions. The optimization at ...

    • Nonmonotonic Reasoning in Design 

      S. H. R. Sham (American Society of Civil Engineers, 1993)
      This paper contends that structural design is a dynamic process whose best example can be found in the active, conjectural, or even vacillating reasoning involved. Nonmonotonic reasoning permeates the design process and ...

    • Editorial 

      Daniel Horn (American Society of Civil Engineers, 1993)

    • XBUILD: Preprocessor for Finite Element Analysis of Steel Bridge Structures 

      M. A. Austin; S. Creighton; P. Albrecht (American Society of Civil Engineers, 1993)
      Historically, the lack of interactive preprocessors to describe tedious finite element models has hindered the use of the finite element method for bridge analysis. The work performed in the present study mitigates this ...

    • Neural Networks Trained by Analytically Simulated Damage States 

      M. F. Elkordy; K. C. Chang; G. C. Lee (American Society of Civil Engineers, 1993)
      Identifying changes in the vibrational signatures of a structure is a promising tool in structural monitoring. Neural networks can be used for this purpose. For a neural network to diagnose damage correctly, it must be ...
