A systematic analytical modelling technique for the simulation of limited-ductile beamcolumn elements based on the concentrated plasticity model is proposed in this paper. The modelling technique employs a backbone curve for the monotonic behaviour of the limited ductile beam-column elements based on empirical equations. The hysteretic behaviour of the beam-columns in the cyclic loading is modelled and calibrated to results from experiments on columns obtained from the literature using OpenSEES software. The modelling technique provides an important tool for the seismic performance assessment of existing buildings which have been designed with considerations of low to no ductile detailing.
