Seismic performance evaluation of masonry infill R.C. frame considering soil-structure interaction

The structural damage due to recent seismic events in Nepal has led a dire need for studies considering soil-structure interaction (SSI) as the majority of designers still adopt conventional design principles. These damages may be result fixed base method’s failure take into account underlying soil properties. Post $$M_w$$ 7.8 Gorkha earthquake, revised National Building code NNBC 105:2020 classified types based on rigidity soil. A comparative analysis is carried out using linear-static and nonlinear static (Pushover) flexible masonry infill RC frame. performance parameter evaluated target inelastic drift 2% are terms their fundamental time period, peak floor displacement, inter-storey ratio (IDR), ultimate load carrying capacity yield mechanism. consideration SSI drastically influenced displacement IDR with decreasing structure exhibited higher load-carrying than all types. dissipated energy by struts. Furthermore, post-yield behaviour models highlighted that level frame elements were base.
