This paper investigates the efficiency of using elastic-gap devices (EGDs) to improve the performance of seismic-isolated bridges (SIBs) in near-fault (NF) zones. The EDG is intended to function at two performance levels under service and maximum considered design level (SDL and MCDL) NF earthquakes to reduce isolator displacements (IDs) while keeping the substructure forces (SFs) at reasonable levels. Analyses of structural models of bridges with EGDs revealed that providing EGD is beneficial for decreasing the IDs to manageable ranges while improving the performance of the isolators by reducing the heat generated.

Performance of seismic-isolated bridges with and without elastic-gap devices in near-fault zones Dicleli, Murat (2008-05-01) In this paper, the efficiency of providing elastic-gap devices (EGDs) to improve the performance of seismic- isolated bridges (SIBs) in near-fault (NF) zones is investigated. The device is primarily made of an assembly of circular rubber bearings and steel plates to provide additional elastic stiffness to the SIB upon closure of a gap. The EDG is intended to function at two performance levels under service and maximum considered design level (MCDL) NF earthquakes to reduce isolator displacements while keepi...
Performance Analysis of Reduced Common-Mode Voltage PWM Methods and Comparison With Standard PWM Methods for Three-Phase Voltage-Source Inverters Hava, Ahmet Masum (2009-01-01) This paper surveys the reduced common-mode voltage pulsewidth modulation (RCMV-PWM) methods for three-phase voltage-source inverters, investigates their performance characteristics, and provides a comparison with the standard PWM methods. PWM methods are reviewed, and their pulse patterns and common-mode voltage (CMV) patterns are illustrated. The inverter input and output current ripple characteristics and output voltage linearity characteristics of each PWM method are thoroughly investigated by analytical...
Performance comparison of inverter control techniques used for the supply of a linear PM synchronous actuator Ben Salem, I.; Ouni, L. El Amraoui; Gillon, F.; Benrejeb, M.; Brochet, P. (2011-09-10) This paper presents performance comparison of three inverter control techniques. These techniques are respectively hysteresis control, MAIM control and direct voltage control (DVC). They are applied for a PM Linear Tubular Synchronous Actuator (PAITI,SA) drive fed, using a three phase voltage source inverter (VSI). This VSI is working with constant switching time intervals as in the standard torque control DTC system.
Design methods for planar and spatial deployable structures Kiper, Gökhan; Söylemez, Eres; Department of Mechanical Engineering (2011) This thesis study addresses the problem of overconstraint via introduction of conformal polyhedral linkages comprising revolute joints only and investigation of special geometric properties for the mobility of such overconstrained linkages. These linkages are of particular interest as deployable structures. First, planar case is issued and conditions for assembling irregular conformal polygonal linkages composed of regular and angulated scissor elements are derived. These planar assemblies are implemented i...
Experimental characterization of collapse-mode CMUT operation Oralkan, Omer; Bayram, Barış; Yaralioglu, Goksen G.; Ergun, A. Sanli; Kupnik, Mario; Yeh, David T.; Wygant, Ira O.; Khuri-Yakub, Butrus T. (2006-08-01) This paper reports on the experimental characterization of collapse-mode operation of capacitive micromachined ultrasonic transducers (CMUTs). CMUTs are conventionally operated by applying a direct current (DC) bias voltage less than the collapse voltage of the membrane, so that the membrane is deflected toward the bottom electrode. In the conventional regime, there is no contact between the membrane and the substrate; the maximum alternating current (AC) displacement occurs at the center of the membrane. I...
