© 2016 Shaban and Caner.The increasingly demanding performance requirements trigger the development of new devices to eliminate the limitations concerning the post-earthquake performance of available seismic protection systems. The prerequisite for economical earthquake-resistant bridges is the structures’ capacity to absorb and dissipate a large amount of seismic energy. A widely considered strategy for enhancing this capacity is through the use of passive energy dissipation systems for seismic protection of structures. It has been known that majority of the available energy dissipation systems are non-usable after a major earthquake, which increases the risk of collapse during an aftershock. The focus of the current study is given to introduce a new type of passive energy dissipation device with a pending patent that is testified to have an improved energy dissipation capacity without suffering any damage while absorbing energy. Thus, the proposed damper does not require an immediate expensive replacement and keeps its operational capabilities and effectiveness during aftershocks. The paper presents the dynamic performance tests of the first full-scale prototype of the damper, that eventually prove it to be a promising design with an improved energy dissipation capacity and stable behavior during and after the dynamic event.

DEVELOPMENT AND CHARACTERIZATION OF SULFIDE BASED ACTIVE MATERIALS FOR ELECTROCHEMICAL APPLICATIONS SAVAŞ UYGUR, CANSU; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2022-6-20) Next-generation electrochemical applications have faced a challenge to be improved in terms of performance with the increasing demand for new technologies. Although oxide-based active materials are widely used material groups in the electrochemical applications, including batteries, electrolyzers, capacitors and electrochemical catalysis, research in nitride/ phosphide/ boride/ sulfide-based active materials are increasing trend topic to overcome the shortcomings of the metal oxide groups. Sulfide-based act...
Optimization of compact electromagnetic energy harvesters for wireless sensor applications Yaşar, Oğuz; Külah, Haluk; Department of Electrical and Electronics Engineering (2017) The developments in wireless sensor systems force researchers to analyze how to satisfy power requirements of these systems. Batteries can be the main candidate to be used as power source; however, they affect negatively the continuity of the wireless systems due to their limited lifetime. In order to provide continuous power source, energy harvester modules are proposed. With the advancements on IC technology, it is possible to convert extracted energies to power sources for the sensors operating in wirele...
Application of an optical fiber-based system for mass movement monitoring Arslan Kelam, Arzu; Akgün, Haluk; KOÇKAR, MUSTAFA KEREM (2022-03-01) This paper assesses the stages and findings of a mass movement monitoring system developed for continuous long-term monitoring applications using optical fiber cable as a sensor to decrease the risks associated with slope instabilities. During this study, a system composed of optical fiber cables and a device referred to as the Brillouin Optical Time Domain Analyzer (BOTDA) has been used. This system has been implemented in a risky landslide area in the Bahcecik region of Kocaeli, one of the active landslid...
Time variant component and system reliability analysis of bridges Ghasemnejad Berenji, Vahid; Akgül, Ferhat; Department of Engineering Sciences (2015) This study aims to develop a time variant reliability algorithm for a bridge component or system capable of incorporating multiple deterioration and live load models to be selected by the user. The algorithm is developed as a shell program built over a previously developed core program (RELSYS) which is based on the First Order Reliability Method (FORM). After reviewing previous research performed on both time invariant and time variant bridge reliability, the fundamental concepts of time variant reliabilit...
Capacitive cmos readout circuits for high performance mems accelerometers Kepenek, Reha; Külah, Haluk; Department of Electrical and Electronics Engineering (2008) This thesis presents the development of high resolution, wide dynamic range sigma-delta type readout circuits for capacitive MEMS accelerometers. Designed readout circuit employs fully differential closed loop structure with digital output, achieving high oversampling ratio and high resolution. The simulations of the readout circuit together with the accelerometer sensor are performed using the models constructed in Cadence and Matlab Simulink environments. The simulations verified the stability and proper ...
