    Time Series Analysis for Vibration-Based Structural Health Monitoring: A Review

    Kong Fah Tee 1,*
    Structural Durability & Health Monitoring, Vol.12, No.3, pp. 129-147, 2018, DOI: 10.3970/sdhm.2018.04316
    Abstract Structural health monitoring (SHM) is a vast, interdisciplinary research field whose literature spans several decades with focusing on condition assessment of different types of structures including aerospace, mechanical and civil structures. The need for quantitative global damage detection methods that can be applied to complex structures has led to vibration-based inspection. Statistical time series methods for SHM form an important and rapidly evolving category within the broader vibration-based methods. In the literature on the structural damage detection, many time series-based methods have been proposed. When a considered time series model approximates the vibration response of a structure and model coefficients… More >

    A “Three-index” Seismic Performance Evaluation Method Based on Sino-US Seismic Code

    Hui Wang1,*, Shuqi Wan2
    Structural Durability & Health Monitoring, Vol.12, No.3, pp. 149-167, 2018, DOI: 10.3970/sdhm.2018.03928
    Abstract The Code for Seismic Design of Buildings (GB50011-2010) in 2016 and the method of seismic performance-based design for high-rise buildings in the Guide for Performance-based Design of High-Rise Buildings (TBI2017) are compared. In view of the characteristics and limitations of the seismic performance index set by the Sino-US seismic code, a “three-index” performance index system and evaluation process considering the displacement angle of the structural interlayer, the plastic damage degree of components and the plastic strain of material is put forward; combining the example of time-history analysis of a out-of-code high-rise building under the rare earthquakes is verified. The results… More >

    Comparative Study on Diagonal Strut Model of Infill Wall

    Zhenling Chai1, Zixiong Guo1,*, Xiaojuan Liu1, Yunfan Jiang1
    Structural Durability & Health Monitoring, Vol.12, No.3, pp. 169-187, 2018, DOI: 10.3970/sdhm.2018.00240
    Abstract The equivalent diagonal strut models of infill wall mainly include the single strut model and multi-strut model. Firstly, several equivalent strut models and their characteristics are introduced in this paper. Then, model analysis and pushover analysis are carried out on infilled frame models with the aid of the software SAP2000. Two typical single strut models and a typical three-strut model are used to simulate the panel of the frames respectively. It is indicated that the period reduction factor of the frame with a three-strut model is close to the value recommended by the current code. The infill wall has great… More >

    Simplified Method and Influence Factors of Vibration Characteristics of Isolated Curved Girder Bridge

    Tongfa Deng1,2, Junping Zhang1,3,*, Mahmoud Bayat4
    Structural Durability & Health Monitoring, Vol.12, No.3, pp. 189-212, 2018, DOI: 10.3970/sdhm.2018.04392
    Abstract The isolated curved girder bridge's vibration characteristics play a major part in the seismic responses of structures and anti-seismic properties. A clear analytic relationship between design parameters and the system's vibration characteristics could be established by its simplified dynamic analysis model, making it convenient for providing a reference to the optimization of design and safety analysis. A double-mass six-degree-of-freedom model for curved girder bridges with isolation bearings installed at the top of the bridge piers is built and a simplified analysis method for the vibration characteristics of the system is provided. Combined with the Matlab programming, the influences of radius… More >
