Onur ZÜBARİOĞLU, a graduate student in the Department of Civil Engineering at Istanbul Gelisim University, has successfully defended his master’s thesis titled “The Effects of Traditional and Base-Isolated Reinforced Concrete Structures on Structural Performance and Material Use.” The thesis was supervised by Asst. Prof. Ahmad Reshad NOORI, Chair of the Civil Engineering Department.
In this study, two versions of the same reinforced concrete structure — one with seismic base isolators and one without — were analyzed and compared. Key performance parameters such as displacement, inter-story drift ratios, and base shear forces were examined, as well as structural material quantities like concrete and reinforcement usage. Modeling and analysis were conducted using licensed versions of ideCAD Statik v11 and ETABS 20 software.
The results showed that seismic isolation significantly improves earthquake performance and reduces upper structure demands. Although the initial cost of base-isolated systems is higher, reductions in material usage provide long-term economic benefits. As a real-world case study, the thesis offers valuable technical and economic insights for similar engineering projects and investment planning.
We sincerely congratulate Onur ZÜBARİOĞLU on this academic achievement and wish him continued success in his career.
