Throughout history, aqueducts have been built to exceed obstacles on the waterway while preserving energy of water. Our priceless cultural heritage, must be protected passed future generations. Filling channel with water can increase earthquake resistance due damping effect Investigating fluid and structure interaction through numerical analysis is crucial understand their behavior under seismic forces. The aqueducts, for which 3D finite element models were prepared, analyzed using combined...

One of the biggest natural energy sources in renewable is undoubtedly wind energy. Huge-sized turbine towers are used for In some cases, tribune 10 meters can be to meet smaller needs. These composed structures such as steel, hybrid and reinforced concrete. Within scope this study, three different types was selected using Fuzzy Analytical Hierarchy Process (BAHS) method which one multi-criteria decision making methods. addition analysis installation maintenance costs, criteria recycling...

Roller compacted concrete (RCC) is a dry mixture often utilized in the construction of large dams. The interlayer RCC dam, which weakest plane structure, can easily fail under hydraulic shear load, geological impact, earthquake force and environmental impact. In this study linear performance analyzes were carried out for eight different scenarios foundation effect, gravity effect empty full reservoir situations. analyses, response Akçakoca Dam, taking into account interaction between dam...

Dams are structures that demand a significant amount of concrete, making them costly constructions. Hence, various alternative methods employed for dam construction, one which is the use Roller Compacted Concrete (RCC). This case study, focuses on examining behavior RCC dams with and without galleries under seismic excitations, considering Akçakoca in Düzce Province. The ground motion data from 1999 earthquake were utilized. impact inside concrete was investigated through stress...

While devastating earthquakes affect cities, they can also cause serious damage to irrigation structures in agricultural areas. Cracks and structural deteriorations may occur water using concrete such as dams, aqueducts open channels. This study investigates the earthquake response of canals through fluid-structure interaction analysis. The an canal was examined by establishing interaction. Finite element models, with material properties dimensions determined, were created analysed...

Marine structures are nowadays used in a variety of ways. The analysis tripod-type offshore structure sixty m total height is performed this study. In addition to operation-related loads, the also under effect wind and wave loads. While Eurocode velocity profile calculate forces, Airy utilized determine forces. model created by finite elements program, composed fluid structural parts. interaction parts ensured Coupled Eulerian Lagrangian (CEL) technique.

Multi-Criteria Decision Making is one of the most important issues, especially when there are numerous competing criteria and alternatives to consider. There a variety approaches for dealing with such issues. The Analytic Hierarchy Process (AHP) popular problem solvers this type problem, it's useful determining weights criteria. Using decision-makers' evaluation tables, method compares each other. Furthermore, employs consistency ratio assess choices. decision maker's experience knowledge...
