Abstract

BASED ON THE FEASIBILITY AND RELIABILITY OF A FORWARD ANALYTICAL MODEL UPDATING METHOD WITH UNIFORM DESIGN HAVING BEEN PROVEN, THIS PAPER STUDIES THE EFFECTIVENESS OF THE METHOD IN THE CONDITION THAT STRUCTURAL MEASURED INFORMATION IS UNCERTAIN AND INCOMPLETE. BY TAKING THE EXPERIMENTAL DATA OF A STEEL TRUSS AS AN EXAMPLE, THIS PAPER STUDIES THE METHOD OF EXPERIMENTAL DATA PROCESSING, THE DETERMINATION OF STRUCTURAL MODEL WITH UNKNOWN PARAMETERS, THE INTERVAL ESTIMATION OF IDENTIFICATION RESULTS AND STEPWISE UNIFORM DESIGN CONSIDERED THE CORRELATION AMONG IDENTIFICATION PARAMETERS. THE RESULTS SHOW THAT THE ERRORS BETWEEN THE NUMERICAL RESULTS COMPUTED BY THE UPDATED MODEL AND THE EXPERIMENTAL DATA ARE ACCEPTABLE, WHICH MEAN THE METHOD IN THIS PAPER IS FEASIBLE AND RELIABLE. IN THE END, BASED ON OUR EXPERIENCES AND LESSONS, WE SUMMARIZE A MODEL UPDATING METHOD FOR COMPLEX STRUCTURES USING STEPWISE UNIFORM DESIGN SCHEMES CONSIDERED THE PRIMARY AND SECONDARY FACTORS, AND EXPOUND ITS COMPUTATIONAL STEPS.
