USE OF MODELS IN STRUCTURAL ENGINEERING

A JUSTIFICATION FOR THE USE OF MODELS IS PRESENTED. MODELS ARE BECOMING INCREASINGLY IMPORTANT IN RESEARCH ON STRUCTURAL CONCRETE; THEY ARE ALSO BEING USED QUITE WIDELY IN THE DESIGN PROBLEM. THE ADVANTAGES AND DISADVANTAGES OF STRUCTURAL MODELS ARE DISCUSSED. SEVERAL CLASSIFICATIONS OF MODELS ARE PRESENTED, INCLUDING ELASTIC VERSUS ULTIMATE STRENGTH MODELS, TRUE VERSUS DISTORTED MODELS, COMPLETE VERSUS PARTIAL STRUCTURAL MODELS, AND DIRECT VERSUS INDIRECT MODELS. EMPHASIS IS ON THE ROLE OF EACH TYPE, AND THE POTENTIALITIES OF EACH TYPE ARE EXPLORED FOR TYPICAL STRUCTURAL PROBLEMS. THE PROBLEM OF HAVING A MODEL BUILT IS EXAMINED BY DISCUSSING THE VARIOUS TYPES OF LABORATORIES AVAILABLE FOR MODEL CONSTRUCTION AND TESTING. EUROPEAN PRACTICE IS REVIEWED, AND RECOMMENDATIONS ARE FORMULATED ON WHAT IS NECESSARY IN THE UNITED STATES IN ORDER TO FURTHER FACILITATE THE USE OF THE PHYSICAL MODELING PROCESS. THE TYPE OF STRUCTURES FOR WHICH MODEL ANALYSIS IS BEST SUITED IS EXAMINED. EMPHASIS THROUGHOUT THE PAPER IS ON PROVIDING THE PRACTICING ENGINEER A BETTER UNDERSTANDING OF THE POSSIBILITIES OF USING STRUTURAL MODELING TECHNIQUES. THE ENTIRE MODELING PROCESS IS PLACED IN A REALISTIC PERSPECTIVE WITH RESPECT TO THE WIDELY USED ANALYTICAL APPROACH. /ACI/
