This paper presents a multi-platform simulation method for the modelling of reinforced concrete infilled frames. The method is developed for multi-scale modelling, where the frame is modelled in detail by two-dimensional elements while the infill wall is represented by equivalent struts. The proposed method not only significantly decreases the computational time compared to the conventional single platform simulation method but also allows the combination of multiple analysis tools with different capabilities. The method is also extended to model the dynamic effects induced by the sudden removal of a supporting column. A special element is developed for such purpose to account for the two analysis phases, i.e., before and after the column removal. The proposed multi-platform method is general and can be implemented in various problems related to the response of masonry infilled frames, e.g., reinforced concrete and steel frames, linear and nonlinear responses, static and dynamic analyses, lateral and vertical loads that represent earthquake and column failure scenarios.
