  • Influence line- model correction approach for the assessment of engineering structures using novel monitoring techniques
    Alfred Strauss, Roman Wendner, Dan M. Frangopol and Konrad Bergmeister
    Abstract; Full Text (3913K)

Abstract
In bridge engineering, maintenance strategies and thus budgetary demands are highly influenced by construction type and quality of design. Nowadays bridge owners and planners tend to include life-cycle cost analyses in their decision processes regarding the overall design trying to optimize structural reliability and durability within financial constraints. Smart permanent and short term monitoring can reduce the associated risk of new design concepts by observing the performance of structural components during prescribed time periods. The objectives of this paper are the discussion and analysis of influence line or influence field approaches in terms of (a) an efficient incorporation of monitoring information in the structural performance assessment, (b) an efficient characterization of performance indicators for the assessment of structures, (c) the ability of optimizing the positions of sensors of a monitoring system, and (d) the ability of checking the robustness of the monitoring systems applied to a structure. The proposed influence line- model correction approach has been applied to an integrative monitoring system that has been installed for the performance assessment of an existing three-span jointless bridge.

Key Words
influence lines model correction approach; model updatimg; fiber optical monitoring systems; LVDT monitoring systems; proof loading.

  • Damage localization in plate-like structure using built-in PZT sensor network
    Xinglong Liu, Chengxu Zhou and Zhongwei Jiang
    Abstract; Full Text (2559K)

Abstract
In this study, a Lamb-wave based damage detection approach is proposed for damage localization in plate. A sensor network consisting of three PZT wafer type actuators/sensors is used to generate and detect Lamb waves. To minimize the complication resulted from the multimode and dispersive characteristics of Lamb waves, the fundamental symmetric Lamb mode, S0 is selectively generated through designing the excitation frequency of the narrowband input signal. A damage localization algorithm based upon the configuration of the PZT sensor network is developed. Time-frequency analysis method is applied to purify the raw signal and extract damage features. Experimental result obtained from aluminum plate verified the proposed damage localization approach.

Key Words
damage localizations; structural health monitoring; Lamb waves; piezoelectric sensors; timefrequency analysis.

  • Vibration mitigation of stay cable using optimally tuned MR damper
    Hongwei Huang, Limin Sun and Xiaolu Jiang
    Abstract; Full Text (5105K)

Abstract
Mechanical dampers have been proved to be one of the most effective countermeasures for vibration mitigation of stay cables in various cable-stayed bridges over the world. However, for long stay cables, as the installation height of the damper is restricted due to the aesthetic concern, using passive dampers alone may not satisfy the control requirement of the stay cables. In this connection, semi-active MR dampers have been proposed for the vibration mitigation of long stay cables. Although various studies have been carried out on the implementation of MR dampers on stay cables, the optimal damping performance of the cable-MR damper system has yet to be evaluated. Therefore, this paper aims to investigate the effectiveness of MR damper as a semi-active control device for the vibration mitigation of stay cable. The mathematical model of the MR damper will first be established through a performance test. Then, an efficient semi-active control strategy will be derived, where the damping of MR damper will be tuned according to the dynamic characteristics of stay cable, in order to achieve optimal damping of cable-damper system. Simulation study will be carried out to verify the proposed semi-active control algorithm for suppressing the cable vibrations induced by different loading patterns using optimally tuned MR damper. Finally, the effectiveness of MR damper in mitigating multi modes of cable vibration will be examined theoretically

Key Words
long stay cable; vibration mitigation; MR damper; semi-active control; performance evaluation.

  • Damage detection from the variation of parameter matrices estimated by incomplete FRF data
    Salam Rahmatalla, Hee-Chang Eun and Eun-Taik Lee
    Abstract; Full Text (2104K)

Abstract
It is not easy to experimentally obtain the FRF (Frequency Response Function) matrix corresponding to a full set of DOFs (degrees of freedom) for a dynamic system. Utilizing FRF data measured at specific positions, with DOFs less than that of the system, as constraints to describe a damaged system, this study identifies parameter matrices such as mass, stiffness and damping matrices of the system, and provides a damage identification method from their variations. The proposed parameter identification method is compared to Lee and Kim

Key Words
frequency response function; dynamic stiffness matrix; receptance; damping matrix; minimization.

  • Experimental study on the vibration mitigation of offshore tension leg platform system with UWTLCD
    Hsien Hua Lee and H.H. Juang
    Abstract; Full Text (6174K)

Abstract
In this research, a typical tension-leg type of floating platform incorporated with an innovative concept of underwater tuned liquid column damper system (UWTLCD) is studied. The purpose of this study is to improve the structural safety by means of mitigating the wave induced vibrations and stresses on the offshore floating Tension Leg Platform (TLP) system. Based on some encouraging results from a previous study, where a Tuned Liquid Column Damper (TLCD) system was employed in a floating platform system to reduce the vibration of the main structure, in this study, the traditional TLCD system was modified and tested. Firstly, the orifice-tube was replaced with a smaller horizontal tube and secondly, the TLCD system was combined into the pontoon system under the platform. The modification creates a multipurpose pontoon system associated with vibration mitigation function. On the other hand, the UWTLCD that is installed underwater instead would not occupy any additional space on the platform and yet provide buoyancy to the system. Experimental tests were performed for the mitigation effect and parameters besides the wave conditions, such as pontoon draught and liquid-length in the TLCD were taken into account in the test. It is found that the accurately tuned UWTLCD system could effectively reduce the dynamic response of the offshore platform system in terms of both the vibration amplitude and tensile forces measured in the mooring tethers.

Key Words
vibration mitigation; Under Water TLCD (UWTLCD); TLP system; experimental water tank testing; stochastic analysis.

    Research and Publication Ethics

    All the editors, publishers, researchers, and peer reviewers of Techno-Press journals strongly encourage to carefully review and follow the Committee on Publication Ethics (COPE) guidelines: https://publicationethics.org/guidance/Guidelines.

    1. Authorship
    Authorship credit should be based on
        (1) Substantial contributors to the conception or design of the work or the acquisition, analysis
       or interpretation of data for the work,
        (2) Drafting the work or revising it critically for important intellectual content,
        (3) Final approval of the version to be published, and
        (4) Agreement to be accountable for all aspects of the work in ensuring that questions related
       to the accuracy or integrity of any part of the work are appropriately investigated and resolved.
    Authors should meet these four conditions after the initial submission of a manuscript and any changes whatsoever in authorship (adding author(s), deleting author(s), or re-arranging the order of authors) must be explained by a letter to the editor from the authors concerned. This letter must be signed by all authors on the paper. Techno-Press does not correct authorship after the final acceptance unless a mistake has been made by the editorial staff. Authorship may be changed before the final acceptance when the authorship correction is requested by all of the authors involved with the manuscript. The corresponding author takes primary responsibility for communication with the journal during the manuscript submission, peer review, and publication process. The corresponding author should be available throughout the submission and peer review process to respond to editorial queries in a timely manner, and should be available to respond to critiques of the work and cooperate with any requests from the journal for data or additional information or questions about the paper even after publication.

    2. Originality, plagiarism and duplicate publication
    Submitted manuscripts must not have been previously published or be under consideration for publication elsewhere. No part of the accepted manuscript should be duplicated in any other journal without the permission of the Editorial Board. Submitted manuscripts are checked for possible plagiarism or duplicate publication upon the paper's arrival. If plagiarism or duplicate publication is detected, the manuscripts may be rejected, the authors will be announced in the journal, and their institutions will be informed. There will also be penalties for the authors. A letter of permission is required for any and all material that has been published previously. It is the responsibility of the author to request permission from the publisher for any material that is being reproduced. This requirement applies to text, figures, and tables.

    3. Conflict of interest statement
    The corresponding author must inform the editor of any potential conflicts of interest that could influence the authors' interpretation of the data. Examples of potential conflicts of interest are financial support from or connections to companies, political pressure from interest groups, and academically related issues. In particular, all sources of funding applicable to the study should be explicitly stated.

    4. Process for managing research and publication misconduct
    When the journal faces suspected cases of research and publication misconduct, such as redundant publication, plagiarism, fraudulent or fabricated data, changes in authorship, undisclosed conflict of interest, ethical problems with a submitted manuscript, appropriation by a reviewer of an author's idea or data, and complaints against editors, the resolution process will follow the flowchart provided by COPE, https://publicationethics.org/guidance/Flowcharts.
    The discussion and decision on the suspected cases are carried out by the Editorial Board.

    5. Editorial responsibilities
    The Editorial Board will continuously work to monitor and safeguard publication ethics:
    * Guidelines for retracting articles;
    * Maintenance of the integrity of academic records;
    * Preclusion of business needs from compromising intellectual and ethical standards;
    * Publishing corrections, clarifications, retractions, and apologies when needed; and
    * Excluding plagiarized and fraudulent data.
    The editors maintain the following responsibilities:
    * Responsibility and authority to reject and accept articles;
    * Avoid any conflict of interest with respect to articles they reject or accept;
    * Promote the publication of corrections or retractions when errors are found; and
    * Preserve the anonymity of reviewers.
