Micro-modelling of stone masonry template buildings as a strategy for seismic risk assessment in developing countries

•Regularisation criteria defined for the use of micro-modelling of irregular masonry.•Micro-modelling of stone masonry using OpenSees replicates analytical results.•Micro-modelling of irregular masonry using OpenSees matches experimental data.•Derivation of fragility curve for masonry through non-linear time history analysis.•Template structures carry low seismic risk if designed to modern Nepalese codes.
