Simplified Nonlinear Analysis of RC Columns Exposed to Lateral Loads

İngilizce (OpenAlex)

In this study, the monotonic and hysteretic behavior of poorly detailed reinforced concrete (RC) columns under lateral loads is simply modeled by SAP2000. It has been shown in literature that the flexural, reinforcement slip and shear deformations is contributed to lateral deformation. The monotonic and hysteretic responses of RC columns due to each of these deformations, were determined. Under pushover loading, deformations due to the flexural, reinforcement slip and shear deformations were summed up to create monotonic behavior of the column. The load-deformation curve from the monotonic model were used to create backbone curve of hysteretic pivot model. The monotonic and hysteretic lateral load- displacement curves obtained in this study were compared with the results obtained from experimental studies. It has been shown that SAP2000 and experimental results were in good agreement and the behavior of poorly detailed RC columns are simplified by SAP2000 instead of using the complex analysis methods.
