      Chris Thewalt; David Moskowitz (American Society of Civil Engineers, 1990)
      A methodology for generating English text from a computer‐processible representation of a design standard is proposed. The machine representation of the standard uses a network of decision tables. A computer program ...
    • PC‐Based Data‐Acquisition System for structural monitoring 

      Harry W. Shenton, III; Nicholas P. Jones (American Society of Civil Engineers, 1989)
      While personal‐computer‐based data‐acquisition systems have become commonplace in the laboratory environment over the past several years, their use as remote, automatically triggered data‐collection systems has been somewhat ...
    • HIBIC: Expert System for Highway Bridge Dynamics 

      D. J. Baker; G. D. Manolis; S. Mohan (American Society of Civil Engineers, 1989)
      The current highway bridge design codes treat the dynamic effect of traffic loads by applying an empirical amplification factor, called the “impact factor,” which is a function of span length only and has little theoretical ...
    • Intelligent Decision Support and Reservoir Management and Operations 

      Slobodan P. Simonovic; Dragan A. Savic (American Society of Civil Engineers, 1989)
      Reservoir management and operations are very complex activities in the field of water resources engineering. During the last two decades, a number of systems analysis techniques, particularly optimization and simulation, ...
    • CSTRUCT: Computer Environment for Design of Steel Structures 

      M. A. Austin; S. A. Mahin; K. S. Pister (American Society of Civil Engineers, 1989)
      CSTRUCT is a computational environment for the structural design and analysis of earthquake‐resistant steel frames. CSTRUCT is currently running on a MicroVax II/GPX workstation. This paper summarizes our recently developed ...
    • Automatic Generation of Seepage Flow Nets by Finite Element Method 

      Fred T. Tracy; N. Radhakrishnan (American Society of Civil Engineers, 1989)
      An analytical method for automatically generating a seepage flow net using the finite element method (FEM) is described. This technique includes a new, more analytical (as compared with numerical) approach to determining ...
    • Knowledge‐Based System for Soil Improvement 

      J. L. Chameau; J. C. Santamarina (American Society of Civil Engineers, 1989)
      The practice of soil improvement has received renewed attention in the last two decades. As a result, existing methods were improved and new ones developed. This paper presents a knowledge‐based decision support system for ...
    • Simulating Construction Robot Agents and Their Knowledge Environment 

      Boyd C. Paulson, Jr.; Nadeem Babar; Lai‐Heng Chua; Thomas M. Froese (American Society of Civil Engineers, 1989)
      In future construction environments, intelligent machines must harness considerable knowledge to plan and control autonomous tasks even though they will be limited in their own knowledge. However, no unifying theory and ...
    • Computer Graphics in Truss‐Model Design Approach 

      Salah Benabdallah; Julio A. Ramirez; Robert H. Lee (American Society of Civil Engineers, 1989)
      The main objective of this paper is to extend and simplify the use of truss models in the design of reinforced concrete members for flexure and shear by means of user‐friendly, interactive computer graphics. An interactive ...
    • Sensitivity Analysis of Construction Contract Prices Using Spreadsheets 

      Foad Farid (American Society of Civil Engineers, 1989)
      “Bad profits” have been identified as the cause of more than one‐half of all business failures in construction. To improve the profitability of the construction contractors, the Fair and Reasonable Markup (FaRM) is defined ...
