A study to determine the effect of variant conditions of framed carrier systems on the flexibility and earthquake behaviors of the building

Keywords: Static pushover analysis, reinforced concrete structures, ducility, reinforced concrete structures earthquake behaviour In this study, the ductility and earthquake behavior of the structures having different carrier system characteristics under the effect of earthquake were investigated. In areas with high earthquake risk, structures were designed with different axle distances and different irregularities and static pushover analysis was performed. Static thrust analysis was applied to all structures examined. Capacity diagrams were created by obtaining displacement requests. With the obtained diagrams, base shear forces, stiffness, ductility, earthquake load reduction coefficients and trans-elastic safety coefficients that affect 7 buildings designed at different axle distances and different irregularities were calculated. As a result of this analysis, it was seen that the axle distances were changed to the corners of the structure and the stiffness and ductility of the structures increased between 40% and 70% in the models where the columns were compacted in the middle part. However, it was observed that the stiffness of the structures decreased between 10-15% in the models with irregularities. Structural ductility increased between 25-35%.
