NUMERICAL MODELLING AND CALIBRATION OF RC COLUMNS UNDER AXIAL LOAD

Abstract eng:
This work presents the first step of a methodology to calculate monetary losses in reinforced concrete moment resisting buildings through an innovative and advanced methodology. This framework involves the correlation between the physical damages that a structural component may experience during seismic events with meaningful engineering demand parameters. The establishment of this correlation constitutes the first phase of the methodology and is obtained through detailed finite element simulations of the critical structural elements. In this paper the development of numerical modeling strategies for the detailed simulations of five columns are described. The paper describes step by step the whole calibration process involving mesh sensitivity studies, evaluation of the influence of the compression fracture energy, geometric nonlinearity, bond-slip action and the buckling of the compressed reinforcements. In order to simplify the problem, pushover analysis is adopted to analyze all the models.
