Nonlinear vibration analysis of functionally graded beams
Dedeköy, Demir; Ciğeroğlu, Ender; Bediz, Bekir; Department of Mechanical Engineering (2022-8)
In this thesis, nonlinear forced vibrations of functionally graded (FG) Euler-Bernoulli Beams are studied. Two types of nonlinearities, large deformation nonlinearity and nonlinearities resulting from rotating beam dynamics, are considered. The Spectral Chebyshev Technique (SCT) is employed for solving governing equations of the spectral-temporal boundary value problems of beam vibrations, which do not always have closed-form analytical solutions. The SCT is combined with Galerkin’s method to obtain spatial...
Nonlinear seismic response evaluation of tunnel form building structures
Balkaya, C; Kalkan, E (Elsevier BV, 2003-02-01)
The occurrences of (M-w = 7.4) Kocaeli and (M-w = 7.1) Duzce earthquakes in Turkey in 1999 once again demonstrate the nondamaged and high performance conditions of RC shear wall dominant structures commonly built by using the tunnel form technique. This study presents their seismic performance evaluation based on the nonlinear pushover analyses of two case studies. The contribution of transverse walls and slab-wall interaction during the 3D action, the effects of 3D and 2D modeling on the capacity-demand re...
Nonlinear Vibrations and Reduced Order Modeling of Bolted Joints
Beyan, Hümeyra; Ciğeroğlu, Ender; Department of Mechanical Engineering (2022-11-29)
Due to ease of mounting, high strength feature and availability, bolted joints are one of the most common and widely used connection method. The contact between connected bodies is ensured by preload force on bolts which affect the stiffness and damping characteristics of the assembled system and introduce nonlinearity. To obtain the dynamic characteristic of systems with bolted joints accurately, the nonlinearity effect should be included. With high fidelity contact model’s accurate response can be obtaine...
Nonlinear vibration analysis of L-shaped beams and their use in vibration reduction
Ekici, Yiğitcan; Ciğeroğlu, Ender; Yazıcıoğlu, Yiğit; Department of Mechanical Engineering (2022-9)
In this thesis, nonlinear vibration analysis of both fixed L-shaped beam and L-shaped beam attached to a single degree of freedom (SDOF) system is performed for several cases with different structural parameters to observe the effect of these parameters. Then these beams are proposed to reduce the vibration amplitudes of certain structures, and the nonlinear effects on the dynamic responses of these structures are investigated. The nonlinear dynamic model of the L-shaped beam is obtained by using Euler-Bern...
