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.

A Computer vision based method for semi-automated rebar detection and measurement of reinforced concrete columns / Hassan, Muhammad Usman; Kurç, Özgür; Department of Civil Engineering (2014) As-built information of reinforced sections is necessary to ascertain structural characteristics from load carrying capacity, serviceability, structural integrity and adherence to code perspective. The objective of this research is to develop a semi-automated structural information acquisition method that can be used to determine as-built information regarding rebar grids of reinforced concrete columns. The technique involves application of photogrammetry, image processing and computer vision knowledge to o...
Finite element implementation of a model to estimate the permanent strain of cyclically-loaded soil Babaoğlu, Muhittin; Erdoğan, Sinan Turhan; Department of Civil Engineering (2020) In vast majority of geotechnical structures such as monopile or strip foundation, which are subjected to repeated loading, long-term resilience of the structures is directly related with the behavior of granular materials subjected to cyclic loading. Repeatedly loaded structure distributes stress to soil that surrounds the structure. When granular materials are exposed to cyclic loading, plastic strain occurs despite the applied stress is less than plastic yield, which results to residual settlement. This t...
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...
Determination of the 1st buckling and collapse loads for integrally stiffened panels by artificial neural network and design of experiment methodology Güzel, Selçuk; Gürses, Ercan (2021-01-22) Buckling is a structural instability that load carrying capacity of a structural element may suddenly decrease. This sudden change in the load carrying capacity may cause catastrophic failures. Therefore, determination of the first buckling and collapse loads of structural elements is essential. FE analyses and structural testing are used to determine buckling characteristics of a structural element. However, in early design stages, FE analyses are time consuming and structural testing is costly. In this pa...
