      T. J. Ross; L. R. Wagner; G. F. Luger (American Society of Civil Engineers, 1992)
      This paper illustrates some specific numerical code applications using an object‐oriented programming (OOP) paradigm. It is the second of two papers describing OOP issues for scientific‐code development. A brief description ...

    • Object‐Oriented Model of Engineering Design Standards 

      James H. Garrett, Jr.; M. Maher Hakim (American Society of Civil Engineers, 1992)
      In almost all engineering fields, design standards are used to ensure an adequate level of safety and serviceability through the specification of performance requirements. The complexity of the information expressed within ...

    • Solid Modeling of RC Beams: 2. Computational Environment 

      J. L. Preston; M. A. Austin (American Society of Civil Engineers, 1992)
      This paper is the second of a two‐part series describing the design and implementation of an interactive reinforced concrete beam design environment called BeamTool. Part two focuses on the issues of implementing and testing ...

    • Comparing Object‐Oriented and Relational Data Models for Project Control 

      Jae‐Jun Kim; C. William Ibbs (American Society of Civil Engineers, 1992)
      This paper examines the object‐oriented data base as an alternative to the traditional, “pure” relational data base for construction project control information. An entity‐relationship (E‐R) model is developed to describe ...

    • Object‐Oriented Programming in Robotics Research for Excavation 

      Darcy M. Bullock; Irving J. Oppenheim (American Society of Civil Engineers, 1992)
      A laboratory study of force‐cognitive robot excavation is described, with particular emphasis on the use of object‐oriented programming (OOP) for rapid prototyping of the computational processes. Unmodeled forces develop ...

    • Combined Symbolic‐Numeric Explosion Damage Assessment for Structures 

      Theodor Krauthammer; Raman Muralidharan; Walter Schmidt (American Society of Civil Engineers, 1992)
      A combined symbolic‐numeric distributed approach has been developed for assessing damage inflicted upon structures by explosions, determining the sequence of structural responses, estimating the causes and applied loads, ...

    • Object‐Oriented Finite Element and Graphics Data‐Translation Facility 

      Jamal A. Abdalla; C. John Yoon (American Society of Civil Engineers, 1992)
      Object‐oriented approaches have emerged as one of the most promising paradigms for developing software. The approach has gained popularity in a number of fields in computer science, such as programming languages, data ...

    • Solid Modeling of RC Beams: I. Data Structures and Algorithms 

      M. A. Austin; J. L. Preston (American Society of Civil Engineers, 1992)
      Solid modeling is the process of building and analyzing geometrically complete representations of points, lines, polygons, and three‐dimensional solid objects. In a functional sense, a model is said to be geometrically ...

    • Coarse‐Grain Parallel Computing Using ISIS Tool Kit 

      Ralph Finch; Shao‐Kong Kao (American Society of Civil Engineers, 1992)
