Dynamic characteristics and performance assessment of reinforced concrete structural walls
Kazaz, İlker; Gülkan, Polat; Department of Civil Engineering (2010)
The analytical tools used in displacement based design and assessment procedures require accurate strain limits to define the performance levels. Additionally, recently proposed changes to modeling and acceptance criteria in seismic regulations for both flexure and shear dominated reinforced concrete structural walls proves that a comprehensive study is required for improved limit state definitions and their corresponding values. This is due to limitations in the experimental setups, such that most previous...
Seismic isolation of foundations by composite liners
Kalpakçı, Volkan; Özkan, M. Yener; Department of Civil Engineering (2013)
In this research, the dynamic behavior of a seismic isolation system composed of high strength geotextile placed over an ultra-high molecular weight polyethylene (UHMWPE) geomembrane (together called as composite liner) beneath the structure is investigated experimentally. The results of the shaking table experiments which were performed on model structures both under harmonic and modified earthquake motions with and without the seismic isolation (composite liner system), are presented in the thesis. The ma...
Dynamic failure of curved CFRP composite laminates under quasi static loading
Çöker, Demirkan (null; 2015-04-15)
In aerospace and wind energy industries, new advances in composite manufacturing technology and high demand for lightweight structures are fostering the use of composite laminates in a wide variety of shapes as primary load carrying elements. However, once a moderately thick laminate takes highly curved shape, such as an L-shape, Interlaminar Normal Stresses (ILNS) are induced together with typical Interlaminar Shear Stresses (ILSS) on the interfaces between the laminas. The development of ILNS promotes mod...
Dynamic modelling and analysis of gun turret elevation drive system
Çiloğlu, Çağıl; Arıkan, Mehmet Ali Sahir; Eren, Oykun; Department of Mechanical Engineering (2016)
In this thesis, dynamic models for the elevation axis of a gun turret are developed by using MATLAB/Simulink and the multi-body dynamics software MSC-Adams. The developed models include the driveline stiffnesses of individual components as well as the viscous damping of the bearings in the elevation drivetrain. State space representations of gun turret model with different degrees of freedoms are presented and compared. Both time and frequency domain analyses are conducted in order to get a basic idea about...
Seismic performance of confined masonry construction
Erköseoğlu, Gülden; Erberik, Murat Altuğ; Department of Civil Engineering (2014)
Although it is a known fact that confined masonry construction has many advantages over unreinforced masonry construction, its application has been very limited in Turkish construction practice. One of the reasons for this issue is that the seismic regulations in Turkey do not explicitly enforce or even encourage the use of confined masonry structural systems. Now, being on the verge of releasing a new version of the Turkish seismic code, it seems to be an appropriate time to adapt confined masonry to the T...
