Redundancy is related to the amount of functionality that the structure can sustain in the worst-case scenario of structural degradation. This paper proposes a widely-applicable concept of redundancy optimization of finite-dimensional structures. The concept is consistent with the robust structural optimization, as well as the quantitative measure of structural redundancy based on the information-gap theory. A derivative-free algorithm is proposed based on the sequential quadratic programming (SQP) method, where we use the finite-difference method with adaptively varying the difference increment. Preliminary numerical experiments show that an optimal solution of the redundancy optimization problem possibly has multiple worst-case scenarios.

Investigation of Trends and Nonstationarity in Hydrologic Variables in the Western Black Sea Basin, Turkey Zaifoğlu, Hasan; Yanmaz, Ali Melih; Baduna Koçyiğit, Müsteyde (2022-08-01) Redundancy is related to the amount of functionality that the structure can sustain in the worst-case scenario of structural degradation. This paper proposes a widely-applicable concept of redundancy optimization of finite-dimensional structures.

Analysis and Control of Complex Flows in U-Bends using Computational Fluid Dynamics Guden, Yigitcan; Yavuz, Mehmet Metin (2014-08-07) Analysis and control of flow structure in U-bends are crucial since U-bends are used in many different engineering applications. As a flow parameter in U-bends, the ratio of inertial and centrifugal forces to viscous forces is called as Dean number. The increase of Dean number destabilizes the flow and leads to a three-dimensional flow consisting of stream wise parallel counter-rotating vortices (Dean vortices) stacked along the curved wall. Due to the curvature in U-bends, the flow development involves com...
Cost Comparison of Reinforced Concrete Structures Designed According to Turkish and European Earthquake Codes Buzuku, Jeton; Gorona, Leart; Tokdemir, Onur Behzat (2020-12-02) Design codes provide methods to analyze and design structures according to different types of risks the structure may suffer, and they differ from each other in several aspects, such as load combinations and earthquake loads evaluation. In this study, the cost of the building designed according to both Turkish and European codes are compared, and cost-effectiveness is measured. The objective of the study is to identify which code provides a more economically feasible design. In consideration of seismic...
Application of volume of fluid (VOF) method in conjunction with shear stress transport (SST) k-ω turbulence closure model to investigate spillway flow Bayrakdar, Fatih; Tokyay Sinha, Talia Ekin; Department of Civil Engineering (2017) Hydraulic engineers often require to assess the reasons and consequences of interaction of flow with structures. Computational Fluid Dynamics (CFD) became a useful tool in this regard in recent years as it provides ample amount of information both on flow and its interaction with its surrounding. To this end, flows over a spillway are investigated. The computational domain for the flow over a spillway is based on the study by Dargahi (2006). Numerical results are compared to previous experimental ones. In t...
Investigation of seismic isolation efficiency for building structures Özdemir, Seda; Yakut, Ahmet; Ay, Bekir Özer; Department of Earthquake Studies (2016) The main goal of this study is to assess the efﬁcacy of seismic isolation for building type of structures with different structural systems, namely, dual systems and moment frame systems having also different number of ﬂoors. Speciﬁc to this study, the main parameters employed for efﬁcacy assessment will be the interstorey drift ratio and ﬂoor acceleration since both structural and non-structural damage to be occured in a system are directly related to these two parameters. To assess the variations in inter...
