    Mehdi Mohammadpour Lima1,2, Dane Miller1, Jeung-Hwan Doh1
    Structural Durability & Health Monitoring, Vol.9, No.4, pp. 269-285, 2013, DOI:10.32604/sdhm.2013.009.269
    Abstract Iran is located in a seismic prone region with several earthquakes occurring annually causing extensive damage to structures and infrastructure. Guilan province is located in the northern part of the country, exhibiting a large population, moderate climate and extensive river system. This region experiences high humidity, several active faults and high seismic hazard potential. This highlights the importance of an active and extensive maintenance and rehabilitation program for the bridges in this region. Structural Health Monitoring (SHM) is an engineering tool used to control changing conditions of infrastructure providing useful information for management, decision making and in certain circumstances code… More >

    Optimal Sensor Placement for Structural, Damage and Impact Identification: A Review

    V. Mallardo1,2, M.H. Aliabadi3
    Structural Durability & Health Monitoring, Vol.9, No.4, pp. 287-323, 2013, DOI:10.32604/sdhm.2013.009.287
    Abstract The optimum location of the sensors is a critical issue of any successful Structural Health Monitoring System. Sensor optimization problems encompass mainly three areas of interest: system identification, damage identification and impact identification. The current paper is intended as a review of the state of the art at the year 2012 and going back to 1990. The above topics have been dealt with in separate contexts so far but they contain interesting common elements to be exploited. More >

    Damage Detection of Cyclically Loaded Concrete Shear Wall using EMI Technique

    A. Likhith Reddy1, Shirleen Charles1, C. Bharathi Priya2, G.V. Rama Rao2, N. Gopalakrishnan3,4 , A. Rama Mohan Rao3
    Structural Durability & Health Monitoring, Vol.9, No.4, pp. 325-347, 2013, DOI:10.32604/sdhm.2013.009.325
    Abstract Details of the investigations on an unexplored application of Electro Mechanical Impedance (EMI) technique using smart piezoelectric (PZT) sensors for damage detection of concrete shear wall structures under crack opening and closing is presented in this paper. The behavior and the ability of this method to detect damages, in a heterogeneous quasi-brittle material is studied for its effective utilization in structural health monitoring. The paper discusses the experimental investigations conducted on a concrete shear wall using PZT patches. Conductance data is acquired at different applied lateral displacements of shear wall. Damage index is calculated using Root Mean Square Deviation (RMSD),… More >

    Finite Element Analysis of Three-dimensional Periodic Notched Plates

    R. Afshar1, F. Berto1,2
    Structural Durability & Health Monitoring, Vol.9, No.4, pp. 349-364, 2013, DOI:10.32604/sdhm.2013.009.349
    Abstract Using the finite element method, three-dimensional models of a number of periodic blunt and sharp notches subjected to tension loading are carried out. The aim of this research is to investigate the thickness effect on the location of maximum stress and notch stress intensity factor (NSIF) of corresponding blunt and sharp periodic notches respectively. With this aim, a wide range of notch geometries are examined. While for two-dimensional plates weakened by periodic notches some results are available in the literature, this paper first faces with the problem of three-dimensional cases. The total of about 100 geometrical configurations are investigated.
