In engineering practice, a competent and effective numerical tool for the comprehensive and accurate analysis of infilled frame structures subjected to different complex load patterns has not been developed. Here, a discrete method of analysis with the damage-based cohesive crack modelling technique is proposed for numerical simulations of masonry-infilled reinforced concrete frame failure. The proposed approach employs the surface-based interaction modelling technique to simulate the interfacial traction-separation behaviour, including mixed modes of fracture, crack propagation, post-fracture behaviour, and finite sliding and separation of the bonded surfaces, between contacting surfaces of masonry units. Applicability of the modelling approach for both masonry and infilled frame structures subjected to different load patterns is checked by performing computer simulations with the proposed model; the model is verified by comparing the results of experimental data. To demonstrate the wide variety of applications of the verified cohesive crack modelling technique, case studies on the non-linear behaviour of infilled frame structures under combined in-plane and out-of-plane loads and subjected to seismic excitation are conducted.
