Structural model calibration of RC structure with two-leaf cavity brick infill wall by deterministic approach

Abstract

An adaptive solution for calibration of a RC structure model with two-leaf cavity brick infill wall, aimed at solving the problem of flexible boundary conditions, is presented in the paper. The structure is simulated with Diana 9.4.4 finite element software. Elastic foundations with interface elements were adopted to overcome stiffness problem in foundations. The validation of the structure was made with the optimization-based modal calibration using MATLAB software. Five calibration types were analysed, and the results obtained were compared with experimental data.
