numerical study on 2d reinforced concrete frames ‎with nonductile columns using ida approach ‎

In recent decades, reliable seismic design of reinforced concrete (rc) structures has been of interest in both practical engineering calculations and research studies. that requires adequate information regarding the ultimate capacities of structural components to withstand the demands (i.e., columns, beams, joints, etc.). several experimental and numerical studies have been carried out to predict the maximum lateral ductility and strength of rc columns with non-seismic detailing due to the crucial role of this type of primary structural element during earthquakes. those resulted in developing some criteria as well as numerical models (elwood and moehle, 2005; azadi and allahvirdizadeh, 2019). the latter can be utilized in numerical simulations of rc structures either based on 1d structural elements or 3d continuumelements (azadi and khanmohammadi, 2018; azadi et al., 2018).
