Abstract


In this study, a five-storey reinforced concrete building was modeled with the IdeCAD V10 program, and the internal force changes in the columns were examined by creating different eccentricity states. While creating the eccentricity, the center of rigidity was moved away from the center of mass by changing the size of one of the corner columns. The columns whose internal strength is examined are the corner, edge and interior columns on the ground, third and fifth floors of the building. As a result of the analysis, the bending moment and shear force values in the ground floor columns have the highest values, while the torsional moment values are higher at the third floor.
