Nonlinear analysis of RC frames retrofitted with structural steel elements
Akpınar, Uğur; Binici, Barış; Department of Civil Engineering (2010)
Deficient concrete structures are serious danger in seismic zones. In order to minimize economical and human loss, these structures should be retrofitted. Selecting suitable retrofitting schemes requires detailed investigation of these systems. Considering these facts, this study aims to calibrate analytical models of systems with chevron braces and internal steel frames; and evaluate their seismic performances. First, analytical models of the frames with braces and internal steel frames were prepared and t...

Nonlinear performance analysis of steel lattice energy distribution towers
Köşker, Yunus Anıl; Baran, Eray; Department of Civil Engineering (2022-2)
Steel lattice tower structures play a vital role in overhead energy transmission and distribution networks. The safety of the towers has a great significance in order to keep power systems functioning. Despite their crucial function, these structures are susceptible to damage and sometimes total collapse as a result of environmental overloading. The collapse of tower structures in varying magnitude has been reported due to changing global weather patterns in the past few years. On January 16th, 2019, strong...
Nonlinear analysis of reinforced concrete frame structures
Çiftçi, Güçlü Koray; Polat, Mustafa Uğur; Department of Civil Engineering (2013)
Reinforced concrete frames display nonlinear behavior both due to its composite nature and the material properties of concrete itself. The yielding of the reinforcement, the non-uniform distribution of aggregates and the development of cracks under loading are the main reasons of nonlinearity. The stiffness of a frame element depends on the combination of the modulus of elasticity and the geometric properties of its section - area and the moment of inertia. In practice, the elastic modulus is assumed to be ...
Nonlinear vibration analysis of rotors supported by ball bearings
Bahan, Doğancan; Ciğeroğlu, Ender; Department of Mechanical Engineering (2019)
Performance of ball bearing-rotor systems is highly dependent on and often limited by characteristics of ball bearings. Ball bearings are nonlinear by their nature and this nonlinearity must be investigated rigorously to correctly predict vibration response of the system. The steady-state periodic response of rotor systems with nonlinear ball bearings is investigated. The rotor is modeled with the Finite Element Method. Nonlinear model for the bearings considers finite number of balls, bearing clearance and...
