Abstract (EN): Masonry-infilled reinforced concrete (RC) frames are a widely adopted building system. Although usually disregarded in design, masonry infills are known to affect the behavior of structures under earthquake loading. Adequate numerical models are therefore required to perform realistic analyses of their behavior under earthquakes. In this context, macro-models are known to be efficient tools for this purpose but their properties need to be calibrated using adequate data and procedures to obtain realistic results. In light of this, procedures to calibrate and define the main parameters of different types of macro-models representing the behavior of masonry infills are proposed. The calibration procedures are first presented for the case of single strut models and are then extended for macro-models with different configurations. The validity and performance of the procedures are then tested for several case studies using experimental data from different RC infilled frame specimens. © 2018, © 2018 Taylor & Francis Group, LLC.
