PRINCIPLES OF MODEL ANALYSIS

THE PRINCIPLES ARE PRESENTED OF MODEL ANALYSIS WITH PARTICULAR REFERENCE TO CONCRETE STRUCTURES. EMPHASIS IS PLACED ON THE USE OF DIRECT MODELS FOR THE STUDY OF BOTH THE ELASTIC AND THE INELASTIC BEHAVIORS UP TO AND INCLUDING THE ULTIMATE STRENGTH. THE SIMILITUDE RELATIONSHIPS ARE SUMMARIZED AND ARE FOLLOWED BY A DISCUSSION OF THE REQUIREMENTS (SUCH AS STRESS-STRAIN RELATIONSHIP, UNIT WEIGHT, FAILURE CRITERION, ETC.) THAT THE MODELING MATERIALS MUST MEET. WHERE THESE REQUIREMENTS CAN NOT BE COMPLETELY SATISFIED, CONSIDERATIONS ARE GIVEN TO THE CONDITIONS AND IMPLICATIONS OF THE USE OF DISTORTED MODELS. SPECIAL PROBLEMS ASSOCIATED WITH MODELING FOR BOND, CRACKING, TIME-DEPENDENT AND THERMAL LOADINGS ARE DISCUSSED. AN EXAMPLE DEALING WITH THE MODELING OF A PRESTRESSED CONCRETE REACTOR VESSEL IS PRESENTED TO ILLUSTRATE BOTH THE APPLICATION OF SIMILITUDE REQUIREMENTS AND SOME OF THE LIMITATIONS OF THE SCALING PROCESS. /ACI/
