    Description / Table of Contents: The study of vibrations and the control of vibrations has been a fundamental cornerstone of engineering. Problems related to vibrations are ubiquitous, from the study of fatigue of airplane wings in turbulent flow to the suppression of vibrations in subsea structures. The breadth of vibration engineering is matched by the depth of field. Numerous methods have been used to understand vibrations, and a wide range of devices have been developed to control vibrations. Many vibration control problems can be considered as a problem of energy dissipation and vibration damping. The problem encompasses multiple interdependent aspects of research and engineering, including the development of models, implementation of algorithms, and design of devices based on data. Discoveries made in one aspect can lead to breakthroughs in other aspects. Thus, the scope and aims of this Special Issue are to receive and accumulate new knowledge about vibration control, especially for topics related to energy dissipation methods for vibration damping. Desired topics include but are not limited to vibration modeling, algorithms for active vibration control, passive damping methods, vibration damping devices, new materials for energy dissipation, etc.

    Description: While the study of vibration and energy dissipation is one of the oldest topics in engineering, it also encompasses some of the most exciting engineering problems of our time. From the exploration of deep sub-sea reservoirs to the stabilization of spacecraft in orbit, the problem of vibration control is ever present. To a certain extent, the technological progress of our civilization is tied to our understanding of vibration, and advances made in this field will only allow us to reach greater horizons. This book attempts to capture a glimpse of our current progress in this field by showcasing over 15 chapters of cutting-edge research performed by world leading experts in vibration control and energy dissipation. We hope the reader will be able to gain an understanding of the state-of-the-art, and if possible, be inspired by the vast scope and possibilities offered by the field of vibration control and energy dissipation.

    Notes: Recently, concrete structures deteriorating for various reasons and upgrading by bondingFRP using epoxy resins has attracted significant researches. Experimental studies in literatesindicate that the anchorage between concrete and FRP laminates plays an important role in thereinforcing design. However, few and no special study has extended to high strength concrete. Thisresearch examines the bond behaviour between FRP laminates and high strength concrete. Toobtain the bond strength and regulation of debonding propagation, a simple face shear type bondtest is conducted. With the explicit material and geometric descriptions and the fairly generalboundary conditions, the interfacial fracture energy release rate, Gf of this test model which is thenused to propose the prediction of the bond strength is derived. Comparison of this energy basismodel in prediction of bond strength with the model of Chen & Teng which has a high accuracy inthis area and results from this experiment demonstrates the derived prediction model as a feasibleand effective measure in analyzing the bond behaviour between FRP and high strength concrete

    Notes: It is important for obtaining the relationship between seismic energies of singledegree-of-freedom (SDOF) systems and multiple degree-of-freedom (MDOF) structures inengineering. In this paper, the formula of hysteretic energy between the MDOF structures andequivalent SDOF systems is developed. Here is also presented the procedure for estimatinghysteretic energy of MDOF structures subjected to severe ground motions employing the energyrelation equation based on equivalent SDOF systems. Eight examples for two regular and sixirregular MDOF structures show that the procedure to obtain the hysteretic energy demands ofMDOF structures may be used as a simple and effective energy estimation method

    Notes: Superelasticity is one of the most important properties of shape memory alloy. In thispaper, the superelastic deformation behavior of NiTi shape memory alloy subjected to cyclic loadingwith stable superelasticity is experimentally investigated. According to test data, a constitutive modelfor the superelasticity of shape memory alloy is presented based on the artificial neural network(ANN). Numerical results agree well with experimental observations that verified the constitutivemodel being of high accuracy. This model can avoid the difficulties of other models on thedetermination of the parameters and is suitable for practical engineering application. Thus, a newmethod is provided for building the constitutive model of shape memory alloy

    Basic and Optimum Column Over-Design Factor Avoiding Story Mechanism for Frame Structures (2007)
    s.l. ; Stafa-Zurich, Switzerland

    Notes: Ductile frame structures are generally designed with column over-design factors (COF)to assure plastic hinges occurring in all beams and avoid unpreferable failure modes. In order toavoid story mechanisms of frame structure constructed with elastic-plastic materials, target COFhas been investigated where the relative occurrence probability of most likely story mechanism islimited within a specific tolerance. In the present paper, the concept of basic and optimum columnover-design factor for avoiding story mechanism are proposed and the value of them for multi-spanmulti-story ductile frames are presented based on a comprehensive investigation on the occurrenceorder of story mechanisms. The basic COF is defined as the critical value that the preferable failuremode and unpreferable failure mode are with the same failure probability, and it is the low limitassuring the entire beam-hinging pattern prior to story mechanisms. For a structure designed with aCOF less than basic COF, the plastic hinges are easier to occur in partial stories to form storymechanism. The optimum COF is the most effective and economy COF to enhance the safety ofstructure, and it is resulted from the shift of priority of plastic hinges in different stories. Therelationships between the basic and optimum COF with calculation parameters are also analyzed inthis paper

    Notes: External bonding fiber reinforced polymers (FRP) to the tension faces of reinforcedconcrete (RC) beam as an effective approach of rehabilitation and strengthening of reinforcedstructures have attracted significant interests of researchers in the past decade. Since theload-carrying capacity of RC beams strengthened with the FRP is dominated by interfacialdelaminated failure, the anchorage strength in FRP to concrete bonded joints under shear and thedebonding stress transferring behavior at the end parts of flexural concrete members bonded withFRP have been deeply studied. Recently, methods of fracture mechanics have been introduced intoanalyzing the above issues. Compared with the traditional methods, the analytical models ofexisting fracture mechanics are reviewed and analyzed. Based on them the debonding bearingcapacity of FRP-strengthened RC beams is calculated and the corresponding finite element modelsare created. These models of fracture mechanics are then evaluated with the finite element resultsand the experimental data from author’s and the literature. Some conclusions with engineeringsignificance are drawn

    Notes: This paper focuses on an experimental investigation and theoretical analysis of differenttypes of RC shear wall with the profile steel braces in two side columns and diagonal profile steelbraces of walls subjected to applied repeated cyclic loads. Fifteen RC shear walls with differentshear span ratio are tested and their aseismic charactertics are studied. The effect of profile steelbracings on failure property, bearing capacity, ductility and hysteretical characteristic of shear wallis investigated based on experimental results. It is shown that adding the profile steel braces on theboundary column and inner of walls can obviously enhance the ultimate strength of specimens andimprove their aseismic characteristics. Finally, the mechanical model of the shear wall is presentedand the formulae for calculating the load-carrying capacity are developed. Numerical analysesindicate that the theoretical results agree well with those from experiments
