Use of Pushover Analysis to Compare the Seismic Response of Columns with Unusual Shapes of Shear Wall

In terms of seismic qualities, a regular RC frame with conventional columns was compared to a regular RC frame with discrete shaped shear walls merely on the frame's perimeter and circular columns employed in the inner half of the RC frame. Static nonlinear analysis, sometimes referred to as push over analysis was used to apply the lateral loads in opposition to the gravity loads. Additionally, the RC structure's overall height was taken into consideration. Push over analysis is used to forecast the post-elastic behaviour of the overall structure under study. The stages of hinge formation assist in determining the structure's performance level. The modelling, analysis, and result interpretation were done using the ETAB software, which is based on the Finite Element Method. Response Spectrum Method was used for push over analysis. The Lateral load application analysis was done using a Displacement controlled approach. At the structure's performance point, all seismic characteristics were compared. The performance point is defined as the point at where the demand and capacity curves intersect. There were three different sets of models made in all, each with a unique horizontal plan geometry. The first set is laid out in a rectangular pattern, the second is in a L-shape, and the third is in a T-shape. The total height of the construction was covered by plan sets. It includes G+6 models for RC frames with square columns and RC frames with asymmetric columns around the frame. According to the findings, RC frames with rectangular columns perform better at withstanding lateral strain than frames with discretely formed shear walls and circular columns for all three sets of models with G+6.
