Comparative Seismic Performance Evaluation of Integral and Conventional Bridges



Arpacıoğlu, Bertan; Kayran, Altan (2019-11-11)
This work presents structural optimization studies of aluminum and composite material horizontal tail plane of a helicopter by using MSC. NASTRAN SOL200 optimization capabilities. Structural design process starts from conceptual design phase, and structural layout design is performed by using CATIA. In the preliminary design phase, study focuses on the minimum weight optimization with multiple design variables and similar constraints for both materials. Aerodynamic load calculation is performed using ANSYS ...
Comparative study of risk measures
Ekşi, Zehra; Körezlioğlu, Hayri; Department of Financial Mathematics (2005)
There is a little doubt that, for a decade, risk measurement has become one of the most important topics in finance. Indeed, it is natural to observe such a development, since in the last ten years, huge amounts of financial transactions ended with severe losses due to severe convulsions in financial markets. Value at risk, as the most widely used risk measure, fails to quantify the risk of a position accurately in many situations. For this reason a number of consistent risk measures have been introduced in...
Comparative evaluation of steel mesh, steel fiber and high performance polypropylene fiber-reinforced concrete in panel/beam tests
Ceylan, Semih; Turanlı, Lütfullah; Department of Civil Engineering (2014)
Comparison of concrete mixtures containing steel mesh, steel fiber and polypropylene fibers were evaluated in terms of toughness, flexural strength, compressive strength and split tensile strength. Five types of concrete were prepared with steel mesh, steel fiber and polypropylene fiber with the identical water/cement (w/c) ratio and the identical workability. 10x60x60 cm plates, 8x8x32 cm beams and 10x20 cm cylindrical concrete specimens were prepared. Compressive strength, split-tensile strength and tough...
Comparative Power Loss Analysis of DCM Flyback Transformer Based on FEA, Numeric Simulation, Calculation and Measurements
Onay, Halil; Suel, Volkan; Ozgen, Tayfun; Hava, Ahmet Masum (2019-01-01)
The flyback transformer is a crucial part of the flyback converter, which has the highest portion of total power losses for most applications. Accurately prediction of the power losses due to flyback transformer early in the design stage provides an advantage about revealing reliable prototypes. In this paper, several loss prediction methods are applied for a 40W universal input and single output DCM flyback transformer as; analytical calculations via well-known Steinmetz and Dowell's formulas, a simulation...
