© 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.Structural optimization of equipment mounted to payload carried externally by jet type fighter are performed by using the loads: artificial neural network (ANN) prediction, experimental and military specification. The main scope of this study is to evaluate the structural response limits proposed by military specifications with real test conditions and also compare the effects of usage ANN predicted and military specification loads in design of aerospace structures. Data used in this study is taken from physically representative Mark-83 with guidance units. Predefined vibration responses in structural optimization is used as power spectral density functions in the frequency domain. Loads for structural design are calculated with random loads using PSD data. Three sigma rule is considered between 20-300 Hz frequency bands. A support structure is optimized according to the ANN predictions, specification suggestions and experimental design loads. Supports designed based on experimental and predicted loads are observed to be lighter than the support designed according to the specification.

Frame finite element model for nonlinear and vibration analysis of steel structures with Beam-Column and Column-Base Semi-Rigid Connections Kiriş-Kolon ve Kolon-Taban Yari-Rijit baǧlantili çelik yapilarin doǧrusal olmayan ve titreşim analizleri için çerçeve sonlu elemani modeli Özel, Halil Firat; Sarıtaş, Afşin (2022-01-01) © 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.In this paper, a shear deformable force-based frame finite element with semi-rigid connections is derived for nonlinear analysis of steel structures. Distributed plasticity approach is defined along element length and section depth, and linear or non-linear semi-rigid connection behavior can be specified anywhere along elements without the necessity to define additional nodes and to increase the degrees of freedom of the structural system.

Technological properties of adobe building materials belonging to Neolithic period: Ulucak Höyük settlement, IOzmir Neolitik dönem kerpiç yapi malzemelerinin teknolojik özellikleri: Ulucak Höyük yerleşimi, Izmir Erol, Fatima; Tavukçuoğlu, Ayşe; Saltik, Emine Nevin Caner (2022-01-01) © 2022 Gazi Universitesi Muhendislik-Mimarlik. All rights reserved.Ulucak Höyük archaeological site (Kemalpaşa, Izmir) is the oldest village settlement known in Western Anatolia. The discovery of the adobe materials' original compositions belonging to Ulucak Höyük Neolithic settlement has vital importance to better understand and sustain the historical adobe technology developed in Anatolia. A comprehensive research was done on the compositional and raw material properties of adobe materials belonging to th...
Drivers’ self-reported reasons of speeding: A Turkish driver sample from two cities Bıçaksız, P.; Doğruyol, B.; Erdost, B.G.; Hoe, C.H.; Gupta, S.; Lajunen, T.; Özkan, Türker (2019-04-01) © 2019, Gioacchino Onorati Editore. All rights reserved.Speeding is an important risk factor of road traffic crashes, and identifying the factors associated with speeding is crucial for road safety. In the present study, face-to-face roadside interviews were conducted to investigate the reasons of speeding among Turkish drivers at six different data collection times in two different cities. A structured interview was administered to collect data from a total of 3317 and 1559 drivers in Ankara and Afyon citi...

Unpredictable Solutions of Impulsive Quasi-Linear Systems Akhmet, Marat; Tleubergenova, Madina; Nugayeva, Zakhira (2022-01-01) © 2022. L&H Scientific Publishing, LLC. All Rights Reserved.The impulsive differential equations with unpredictable perturbations are under investigation. The definition of the discontinuous unpredictable function with the discrete unpredictable set of discontinuity moments is introduced. The existence and uniqueness of asymptotically stable discontinuous unpredictable solutions for quasi linear systems are proved. Examples with simulations are given to illustrate the results.
