Abstract:
The wave energy converter captures the wave power by buoy’s heaving motion, transfers it by hydraulic system, and converts it into the electric power by generator. The hydraulic conversion system plays an important role that can realize the effective regulation of the output power. In order to develop the working characteristics of the hydraulic transmission system, a new wave energy experimental platform was devised. The platform adopts the matching design mode of the driving oil cylinder and the driven oil cylinder. The active hydraulic cylinder and the clump weight can simulate the movement of the oscillating float under certain sea conditions, and the driven oil cylinder realizes the conversion and the output of wave energy. In order to improve the operation accuracy of the active hydraulic cylinder, the control strategy of the active hydraulic cylinder was studied. An adaptive sliding mode control strategy based on the back-stepping method was proposed to overcome the influence of the parameter uncertainty in state equation. The adaptive law was designed by Lyapunov criterion to ensure the stability and the convergence of the closed-loop system. The proposed control strategy was verified and compared with proportional integral derivative control strategy through the concrete experiment, which shows the rapidity and the stability of it. The hydraulic transmission system of wave energy converter was developed; at the same time, the characteristics of hydraulic regulation under different working conditions were summarized through experiments. The results of the research could be the guidance for the power control design.

Abstract:
Exploitation of green energy sources is essential to diminish the deterioration of our environment. The energy harvesting, represents an alternative to achieve greater range in electric and hybrid vehicles. An energy management strategy (EMS) must be optimized to obtain the best benefits in such vehicles, which is not a trivial task. If harvesting or energy recovery devices are added, the EMS becomes a dual-purpose algorithm: minimizing fuel consumption and maximizing energy harvest through maximum power point tracking (MPPT) controllers. Known studies consider separate EMS, one for traction and another for regenerative braking, without considering harvest devices such as solar panels, regenerative suspension, thermal generators, among others. Furthermore, the electronic power converters used, are not designed to handle such unequal power levels. In this article, an electronic platform to include multiple energy harvesting devices in a fuel-cell hybrid electric vehicle, was presented together with a multiple MPPT-EMS. The EMS is easily implementable, and considers quasiconstant cell energy extraction and filtering of current transients to the battery bank ensuring the longevity of the devices. A new mathematical model of the platform, a closed loop stability analysis, and numerical and Hardware-in-the-Loop (HIL) validations were presented. Some experimental validation results were also provided.

Abstract:
Floating offshore wind turbines have great potential for harvesting renewable energy sources since offshore wind is stronger and more stable than onshore wind. The foundations of floating offshore wind turbines are not rigidly fixed and it leads to vibration of the floating platform pitch angle. This vibration is caused by fast blade pitch angle motions of variable speed control for controlling rotor speed at rated values. This study proposes a control method to address this vibration, floating platform vibration control. This method extracts a natural frequency component of the vibration from the floating platform pitch angle signal by a band pass filter and controls the blade pitch angle on the basis of proportional–derivative control. Its key characteristic is changing control modes in accordance with electrical power. Experiments using a full-scale spar-type floating offshore wind turbine were performed, and results show that the proposed floating platform vibration control can suppress the vibration of floating platform pitch angle.

Abstract:
Freak waves have great peak energy, short duration, great contingency, and strong nonlinear characteristics, and can cause severe damage to ships and marine structures. In this study, numerical simulations in conjunction with experimental tests are applied to study air gap response and wave slamming loads of a semi-submersible offshore platform under a freak wave. A three-dimensional wave tank, which is created based on the computational fluid dynamics (CFD) method, is applied to study the hydrodynamic responses of a semi-submersible platform. The numerical model of the tank and offshore platform system are checked according to the experimental results. A typical freak wave is modelled in numerical wave tanks by the linear superposition method, and its significant wave height is 13.03 m. It is found that the freak wave is closely associated with the wave slamming. The appearance of the freak wave gives rise to a negative air, gap which appears on the side of the back wave surface at the bottom of the deck box, and considerable slamming pressure is generated. Furthermore, the wave run up at the junction of the column and the buoyancy tank is also seen due to the freak wave.

Abstract:
To deal with the difficulty to obtain a large number of fault samples under the practical condition for mechanical fault diagnosis, a hybrid method that combined wavelet packet decomposition and support vector classification (SVC) is proposed. The wavelet packet is employed to decompose the vibration signal to obtain the energy ratio in each frequency band. Taking energy ratios as feature vectors, the pattern recognition results are obtained by the SVC. The rolling bearing and gear fault diagnostic results of the typical experimental platform show that the present approach is robust to noise and has higher classification accuracy and, thus, provides a better way to diagnose mechanical faults under the condition of small fault samples.

Abstract:
The influence of electromagnetic induction coil launcher (EICL) system parameters on the launch performance was analyzed, and a method for measuring the launch performance of an EICL system with a muzzle velocity and energy conversion efficiency was proposed. The EICL system mainly includes a pulse power supply and launcher. The parameters of the pulse power supply mainly include the discharge voltage and the capacitance value of the capacitor bank. The structural parameters of the launcher mainly include the bore size of the launcher, the air gap length between the armature and the drive coil, the length and width of the drive coil, and the trigger position of the armature. Change in single or multiple parameters in the launch system will influence the launch performance. The influence of single or multiple parameters on the launch performance was summarized, and the physical law as analyzed. The influence law of the EICL system parameters on the launch performance was obtained, which lays a theoretical foundation for the optimization design of EICL. Finally, experimental verification was carried out by a single-stage test platform.

Abstract:
Based on the single-phase H-H power unit topology in the novel co-phase power supply system, with the back-to-back grid-connected operation method, this paper aimed at solving the problem that in experiment, system capacity constraints caused the failure to achieve unit full power output and proposed the strategy of rectifier voltage, current double closed loop and full disturbance feed-forward control. Finally, based on the digital signal processor (DSP) and complex programmable logic device (CPLD), this study constructed a hardware platform of the power unit control system. Experimental results show that the system is stable, achieving two-way flow of energy.

Abstract:
In this study, a fault diagnosis system is proposed for rolling ball bearing race using wavelet packet transform(WPT) and artificial neural network(ANN)technique. Vibration signal from ball bearings having defects on inner race and outer race is considered and the extraction method of feature vector based on wavelet packet transform with frequency band energy is used. The vibration signal is decomposed into the individual frequency bands. The variations of the signal energy in these bands reflect the different fault locations. Further, the artificial neural network is proposed to develop the diagnostic rules of the data base in the present fault identification system. The experimental work is performed to evaluate the effect of fault diagnosis in a rolling ball bearing platform under different fault conditions. The experimental results indicate the effectiveness of the proposed method in fault bearing identification.

Abstract:
In order to find the programs that can be generated at low frequency, a scheme of using (polyvinylidene fluoride) piezoelectric film to collect the energy of human foot movement is proposed, and related theoretical analysis and experimental studies are conducted. The solution is capable of energy harvesting during low-frequency walking to provide power for wearable microelectronic devices. First, a system dynamics model was built to analyze the kinematics of the foot, and then COMSOL Multiphysics simulation software was used to simulate the vibration mode, stress–strain, and output voltage of the piezoelectric film. Finally, the experimental platform was built for experimental testing. The experimental results show that when the PVDF piezoelectric film on the back of the human foot is deformed, the output power will vary in a certain range. When the thickness of the piezoelectric film is 122 μm and the bending amplitude is 60°, the maximum output voltage in the experiment is 25.2 V, the output current is 0.0783 mA and the output power is 1.981 mW. The experimental results verify the feasibility of the scheme design and provide a new solution for powering electronic components.

Abstract:
A flat band structure in momentum space is considered key for the realization of novel phenomena. A topological flat band, also known as a drumhead state, is an ideal platform to drive new exotic topological quantum phases. Using angle-resolved photoemission spectroscopy experiments, we reveal the emergence of a highly localized surface state in a topological semimetal BaAl4 and provide its full energy and momentum space topology. We find that the observed surface state is localized in momentum, inside a square-shaped bulk Dirac nodal loop, and in energy, leading to a flat band and a peak in the density of state. These results imply this class of materials as an experimental realization of drumhead surface states and provide an important reference for future studies of the fundamental physics of correlated quantum effects in topological materials.

Abstract:
Ce travail de thèse présente la supervision, l'analyse et l'optimisation des systèmes de distribution d'électricité, considérant en particulier la pénétration des ressources distribuées d'énergie renouvelable et les moyens de stockage d'énergie. La planification de ces systèmes commence à devenir un problème croissant dû à la dérégulation dans la production d'électricité, les changements dans la politique environnementale, l'introduction des nouvelles technologies et la transformation vers la définition d'un réseau électrique intelligent. En conséquence, l'utilisation d'outils de modélisation et d'analyse pour l'évaluation de ces systèmes électriques en pleine évolution, attirent de plus en plus l'attention des planificateurs et opérateurs. Ceci a donné lieu au développement d'une plateforme expérimentale temps réel, et a permis de concrétiser le nouveau concept de gestion énergétique dans un territoire de Banque de l'Energie, introduit dans le projet VERTPOM®. Cette plateforme couvre tous les aspects des challenges concernant les futures exigences dans un réseau électrique de distribution, relatives à l'optimisation de la gestion dans la production et la consommation locales d'énergie électrique. Une installation matérielle/logicielle avec intérêt pour l'utilisation des outils de modélisation et d'analyse temps réel, avec quelques références d'application, est décrite également. En plus, une nouvelle méthodologie d'intégration d'un système de stockage d'énergie dans un réseau de distribution d'électricité réel est proposée, avec l'utilisation de capacités de calcul parallèle de la plateforme expérimentale. La localisation de ce système est obtenue grâce à une analyse de sensitivité, tandis que le dimensionnement en puissance est donné par le déploiement d'un algorithme génétique. Les résultats obtenus dans ces conditions démontrent l'efficacité de la technique de parallélisation proposée, qui montrent également, que l'amélioration du profil de tension et la réduction des pertes de puissance techniques, sont possibles grâce à l'intégration des moyens de stockage d'énergie dans le système électrique
This thesis presents the supervision, analysis and optimization of power distribution systems considering the penetration of distributed energy resources and energy storage systems. The power distribution system planning is becoming an increasingly issue due to the deregulation of the power industry, the environmental policy changes, the introduction of new technologies and the transformation towards a smart power distribution grid definition. In consequence, the use of modeling and numerical evaluation tools is getting more attention for the system planners and operators. This has resulted in the development of a real-time experimental platform belonged to the Bank of the Energy concept. The platform covers all aspects of the challenges of future power system requirements related to the optimization of the local energy production and consumption. A hardware/software setup with emphasis to the utilization of real-time simulation and hardware in the loop testing with some typical reference applications are described. Additionally, it is proposed a novel methodology for battery energy storage systems (BESS) integration over a real distribution system using the parallel computing capabilities of the experimental platform. The placement of BESS is performed by a sensitivity analysis, while the output power rating sizing is deployed using a genetic algorithm. The outcomes of this methodology demonstrate the effectiveness of the proposed parallelization technique and show that voltage profile improvement and losses reduction are possible introducing the BESS into the system

Abstract:
L'Internet des Objets a pour but d'intégrer des milliards d'objets connectés dans l'Internet.Du point de vue matériel, ces objets connectés sont de petits ordinateurs très bon marché, basés sur des micro-contrôleurs et des puces radio efficaces en énergie apparus récemment, couplés avec des capteurs et actionneur divers, le tout alimenté par une batterie de très petite taille.Ces objets connectés sont donc typiquement très contraints en ressources telles que CPU, mémoire et énergie.De plus, les liens radio à travers lesquels communiquent les objets connectés ont une capacité très limitée, sont souvent sujet à des taux de perte importants, et peuvent requérir du routage spontané entre objets connectés pour fournir la connectivité nécessaire.Ces caractéristiques posent des défis, d'une part en termes de logiciel embarqué s'exécutant sur les objets connectés, et d'autre part en termes de protocols réseaux utilisés par les objets connectés pour communiquer.En conséquence, de nouvelles méthodes et outils expérimentaux sont nécessaires pour étudier in vivo les réseaux formés d'objets connectés, de nouvelles plateformes logicielles sont nécessaires pour exploiter efficacement les objets connectés, et des protocoles de communication innovants sont nécessaire pour interconnecter ces objets.La présente thèse relève en partie ces défis, en introduisant des nouveaux outils facilitant l'utilisation de grands réseaux test interconnectant de nombreux objets connectés, un nouveau système d'exploitation (RIOT) utilisable sur une très grande variété d'objets connectés, ainsi que plusieurs nouveaux mécanismes utilisant le paradigme des réseaux centrés contenus pour améliorer significativement l'efficacité énergétique des protocoles de communication standards de l'Internet des Objets
The Internet of Things aims to seamlessly integrate billions of so-called Smart Objects into traditional Internet infrastructures.From the hardware perspective, Smart Objects emerged when tiny, cheap computers became available, combining energy efficient micro-controllers, low-power radio transceivers, and sensors as well as actuators interacting with the physical world, often powered by batteries.Typically, Smart Objects are thus heavily constrained in terms of CPU, memory and energy resources.Furthermore, wireless links used for communication among Smart Objects or towards the Internet are often slow, subject to high packet loss, and may require spontaneous store-and-forward among peer Smart Objects to ensure connectivity.Such characteristics pose challenges, on one hand in terms of software running on Smart Objects, and on the other hand in terms of network protocols Smart Objects use to communicate.In consequence, novel evaluation methods and experimental tools are needed to study Smart Object networks in vivo, new software platforms are needed to efficiently operate Smart Objects, and innovative networking paradigms and protocols are required to interconnect Smart Objects.This thesis addresses these challenges by introducing new tools for large scale testbed-driven experimental research, a novel operating system (RIOT) applicable to a wide variety of connected Smart Objects, and several new mechanisms leveraging information-centric networking which significantly improve energy-efficiency compared to state-of-the-art network protocols in the Internet of Things

This research focuses not only on the interaction between the floating platform for cage aquaculture and the waves but also on the incident wave′s energy transformation. The floating platform was simulated with a 1:30 physical scale model in the hydrodynamic laboratory. A total four wave gages and one load cell were used in this study: two wave gages installed in the upstream of the platform, one gage in the net cage and one gage in the downstream side of the platform; while one load cell measuring the mooring line tension at the anchor. All of the measurements were recorded in the data acquisition system for further analyzing reflected waves, transmitted waves, the wave height in the net cage, and the correspondent mooring line tensions. Furthermore, the movement of the platform and volume deformation of the fish net are recorded by the video camera, and then analyzed by the image processing method. First, the true color images were transferred into grayscale images, and then passed through mean filter, noise filter and median filter step by step. Finally, a weighted-algorithm was used to calculate the coordinates of the desired point form the resulted image matrix. Thus, the motion of the floating platform and the volume deformation of the fish net can be obtained by analyzing the variation of these points captured through the image processing procedure. For the ability of resistance to wave attack for a floating platform, it often estimated by inspecting the reflection and transmission coefficients of the platform. Besides the function of wave resistance ability, the stability of the floating platform, maximum tension in the mooring lines and the net volume deformation coefficient are also important factors for optimum design of a cage platform. According to the results of this research, we conclude some important facts as below: (1) For short-period waves, the net mesh size and twine diameter have influenced the magnitude of reflected waves and the motion of platform; and it makes little difference in the transmission coefficients, wave height ratios inside of net cage, and the maximum tension force in the mooring cable. (2)With the respect of transmitted wave coefficients: the wave transmission phenomena are not obvious for short-period waves, but these phenomena will gradually increase when the incident wave periods are getting longer. (3)Under the pure wave test condition, the net volume deformation coefficients are about 1% only, which means that the deformation of the fish net does not change at all, and it may be due to the overweight of the bottom frame. (4) Tension-leg type mooring system seems able to provide better stability of the platform than catenary type mooring system.

Even with technological development, and the increase in the use of renewable energy sources in recent years, 14% of the global population still does not have access to electricity. Pico-hydro systems can be a solution both for lack of grid access and for distributed generation. One of the main challenges for this technology dissemination lies in the fact that the design of the system depends on the characteristics of the place where it will be installed. Thus, a platform that allows the emulation of real conditions in a controllable environment is an interesting option to estimate the system requirements and its production. This work describes the implementation of an experimental platform for emulation and analysis of pico-hydro systems, grid-connected and also stand alone solutions. With this platform, tests were carried out on 4 types of turbines connected to the electric grid. A low head turbine (1,5 to 5 m) propeller type, a Turgo turbine for heads up to 30 m, a pelton turbine for heads up to 90 m and a horizontal water wheel. The tests carried out with the propeller turbine and the water wheel are fundamental for the ongoing projects in the House of Silk and the Castrelos Aquaculture Centre.
Mesmo com o desenvolvimento tecnológico e o aumento na utilização de fontes de energia renováveis nos últimos anos, 14% da população mundial ainda não possui acesso a rede elétrica. Sistemas pico-hídricos podem ser uma solução tanto para falta de acesso a rede, quanto em relação a geração distribuída. Um dos principais desafios para a disseminação dessa tecnologia, está no fato de que o projeto do sistema depende das características do local onde este será instalado. Assim, uma plataforma que possibilite a emulação de condições reais em ambiente controlável é uma opção interessante para estimar os requisitos do sistema e sua produção. Este trabalho descreve a implementação de uma plataforma experimental para a emulação e análise de sistemas pico-hídricos, ligados a rede ou isolados. Com esta plataforma, foram realizadoos ensaios em 4 tipos de turbinas ligadas a rede elétrica. Uma turbina de baixa queda (2 - 5 m) do tipo hélice, uma turbina tugo para quedas até 30 m, uma turbina pelton para quedas até 90 m e uma roda de água horizontal. Os ensaios realizados com a turbina de hélice e a roda de água são fundamentais para os projetos em curso na Casa da Seda e no Centro Aquícola de Castrelos.

Abstract:
AbstractDiffusion acts as a fundamental process for both energy and mass movement, showcasing dynamics that differs from wave propagation. The emergence of metamaterials provides a robust platform for custom manipulations of mass diffusion, drawing on principles like transformation theory and scattering-cancellation theory. Such manipulations have set the stage for novel findings and pioneering applications. This chapter delves into a thorough analysis of the recent progress in diffusion metamaterials. Earlier studies are methodically categorized based on diffusion models, delving deeply into the related theories, applications, finite-element simulations, and experimental approaches of different mechanisms. The chapter wraps up with a scrutiny of the inherent challenges tied to the theoretical underpinnings and architectural design of diffusion metamaterials. Some of these challenges are seen as potentially mitigated by upcoming approaches, such as pseudo-conformal mapping and machine-learning methodologies.

Abstract:
This Chapter presents a comparative study between two current control techniques, namely, conventional Delta Modulator and novel Delta-Sigma Modulator. The use of Delta modulator in variable speed drives poses a problem of noise while converting analog signal in to digital form; to optimize Pulse Width Modulated (PWM) inverter waveforms on-line without any optimization process. But in the Delta-Sigma Modulator the noise varies. It can be successfully applied to over-sampling digital-to-analog and analog-to-digital data converters, switch mode power supplies and inverters It is easy to implement, smooth inverter operation and provides low harmonics at the inverter output. The comparative study between the above said current controllers has been verified by the MATLAB computer simulation in terms of the high frequency power spectra, average switching frequency, rms current error and total harmonic distortion of load current waveforms. The obtained theoretical results are validated with experimental platform based on TMS320F2812 digital signal processor for effectiveness of the study.

Abstract:
Hydrogen production from water via efficient solar based photocatalytic or photoelectrochemical processes could play a major role in the energy regimes of the future. Here, intermittent solar energy is converted into the promising energy vector hydrogen for later carbon free use on demand. Although much effort has been made in the last years photocatalytic/photoelectrochemical systems with acceptable solar-to-hydrogen-efficiency for economic operation could not be introduced, yet. Within the project DuaSol simultaneous hydrogen generation and water treatment in a photoelectrochemical tandem cell is investigated as a potentially economic process. Organic contaminants are oxidised by interaction with photo-generated electron holes at the photoanode. Produced protons approach the photocathode to react with photo-generated electrons to form hydrogen. Experiments with photocatalytic systems employing DLR’s 2-axis tracking modified linear Fresnel solar concentrator SoCRatus (Solar Concentrator with a Rectangular Flat Focus) were carried out in order to set a reference for the further experimental assessment. Diverse photocatalysts based on titanium dioxide (TiO2) and tin niobate (SnNb2O6) were tested in a planar suspension reactor with two parallel reaction chambers irradiated in the focal plane of the SoCRatus. The evolution of hydrogen was measured and correlated to the overall solar input and to spectral quantities. Three temperature levels, mostly 25°C, 37.5°C, and 50°C, were considered and maintained during the experiments in order to study temperature related effects. Methanol as a sacrificial reagent or rather a model substance for organic contaminants formed part of the suspension with a volume fraction of 10% at 20°C. As expected regarding the band gaps of the considered TiO2 based photocatalysts the hydrogen output is predominately affected by the applied UV portion. The UV fraction of solar light varies significantly in the course of a day and coherently also the production of hydrogen. Hydrogen was generated at rates as high as 7386 μmol/h. Regarding the SnNb2O6 based photocatalysts the generation of hydrogen rather corresponds with the irradiance in the visible range. The solar-to-hydrogen efficiency as well as the photon efficiency in different spectral ranges could be calculated. In addition an extensive analysis of the uncertainty of experimental results was conducted. It could be confirmed that the SoCRatus is an excellent platform for the experimental assessment of photocatalytic / photoelectro-chemical systems under practical conditions.

Abstract:
Bridges often serve as key links in local and national transportation networks. Bridge closures can result in severe costs, not only in the form of repair or replacement, but also in the form of economic losses related to medium- and long-term interruption of businesses and disruption to surrounding communities. In addition, continuous functionality of bridges is very important after any seismic event for emergency response and recovery purposes. Considering the importance of these structures, the associated structural design philosophy is shifting from collapse prevention to maintaining functionality in the aftermath of moderate to strong earthquakes, referred to as “resiliency” in earthquake engineering research. Moreover, the associated construction philosophy is being modernized with the utilization of accelerated bridge construction (ABC) techniques, which strive to reduce the impact of construction on traffic, society, economy and on-site safety. This report presents two bridge systems that target the aforementioned issues. A study that combined numerical and experimental research was undertaken to characterize the seismic performance of these bridge systems. The first part of the study focuses on the structural system-level response of highway bridges that incorporate a class of innovative connecting devices called the “V-connector,”, which can be used to connect two components in a structural system, e.g., the column and the bridge deck, or the column and its foundation. This device, designed by ACII, Inc., results in an isolation surface at the connection plane via a connector rod placed in a V-shaped tube that is embedded into the concrete. Energy dissipation is provided by friction between a special washer located around the V-shaped tube and a top plate. Because of the period elongation due to the isolation layer and the limited amount of force transferred by the relatively flexible connector rod, bridge columns are protected from experiencing damage, thus leading to improved seismic behavior. The V-connector system also facilitates the ABC by allowing on-site assembly of prefabricated structural parts including those of the V-connector. A single-column, two-span highway bridge located in Northern California was used for the proof-of-concept of the proposed V-connector protective system. The V-connector was designed to result in an elastic bridge response based on nonlinear dynamic analyses of the bridge model with the V-connector. Accordingly, a one-third scale V-connector was fabricated based on a set of selected design parameters. A quasi-static cyclic test was first conducted to characterize the force-displacement relationship of the V-connector, followed by a hybrid simulation (HS) test in the longitudinal direction of the bridge to verify the intended linear elastic response of the bridge system. In the HS test, all bridge components were analytically modeled except for the V-connector, which was simulated as the experimental substructure in a specially designed and constructed test setup. Linear elastic bridge response was confirmed according to the HS results. The response of the bridge with the V-connector was compared against that of the as-built bridge without the V-connector, which experienced significant column damage. These results justified the effectiveness of this innovative device. The second part of the study presents the HS test conducted on a one-third scale two-column bridge bent with self-centering columns (broadly defined as “resilient columns” in this study) to reduce (or ultimately eliminate) any residual drifts. The comparison of the HS test with a previously conducted shaking table test on an identical bridge bent is one of the highlights of this study. The concept of resiliency was incorporated in the design of the bridge bent columns characterized by a well-balanced combination of self-centering, rocking, and energy-dissipating mechanisms. This combination is expected to lead to minimum damage and low levels of residual drifts. The ABC is achieved by utilizing precast columns and end members (cap beam and foundation) through an innovative socket connection. In order to conduct the HS test, a new hybrid simulation system (HSS) was developed, utilizing commonly available software and hardware components in most structural laboratories including: a computational platform using Matlab/Simulink [MathWorks 2015], an interface hardware/software platform dSPACE [2017], and MTS controllers and data acquisition (DAQ) system for the utilized actuators and sensors. Proper operation of the HSS was verified using a trial run without the test specimen before the actual HS test. In the conducted HS test, the two-column bridge bent was simulated as the experimental substructure while modeling the horizontal and vertical inertia masses and corresponding mass proportional damping in the computer. The same ground motions from the shaking table test, consisting of one horizontal component and the vertical component, were applied as input excitations to the equations of motion in the HS. Good matching was obtained between the shaking table and the HS test results, demonstrating the appropriateness of the defined governing equations of motion and the employed damping model, in addition to the reliability of the developed HSS with minimum simulation errors. The small residual drifts and the minimum level of structural damage at large peak drift levels demonstrated the superior seismic response of the innovative design of the bridge bent with self-centering columns. The reliability of the developed HS approach motivated performing a follow-up HS study focusing on the transverse direction of the bridge, where the entire two-span bridge deck and its abutments represented the computational substructure, while the two-column bridge bent was the physical substructure. This investigation was effective in shedding light on the system-level performance of the entire bridge system that incorporated innovative bridge bent design beyond what can be achieved via shaking table tests, which are usually limited by large-scale bridge system testing capacities.
