    Latitude-Time Total Electron Content Anomalies as Precursors to Japan's Large Earthquakes Associated with Principal Component Analysis by Jyh-Woei Lin

    Published 2011-01-01
    “…According to the results, PCA was able to discriminate clear TEC anomalies in the months when all 18 earthquakes occurred. After reviewing months when no M≥6.0 earthquakes occurred but geomagnetic storm activity was present, it is possible that the maximal principal eigenvalues PCA returned for these 18 earthquakes indicate earthquake associated TEC anomalies. …”

    Investigation of Small-Scaled Soil Structure Model under Earthquake Loads via Small Shaking Table Tests by Mohammed El Hoseny, Jianxun Ma, Dong Luo, Yanchao Yue

    Published 2022-01-01
    “…In addition, the laminar soil container for the soil block was constructed to reduce undesirable boundary effects. Three earthquakes have been applied at the superstructure base as a fixed base and at the bottom of the soil block in the soil structure system as a flexible base. …”

    Seismic Performance Assessment of Ordinary Moment Resisting Frame Equipped with Viscous Dampers under Pulse-Like Earthquakes by Amir Yousefpour, Hamid Mazidababdi Farahani, Mohsen Ali Shayanfar

    Published 2022-01-01
    “…In conventional structures, the earthquake-resistant design is based on flexibility after yielding of structural members to provide a loss of earthquake input energy, while, using dampers, the input energy loss can be concentrated in predetermined points to prevent the nonlinear behavior of the main members that are also in the gravity bearing path. …”

    Detection of Earthquake-Induced Damage in a Framed Structure Using a Finite Element Model Updating Procedure by Eunjong Yu, Seung-Nam Kim, Taewon Park, Sang-Hyun Lee

    Published 2014-01-01
    “…In addition, a modified frame element which included rotational springs was used to construct the FE model for updating to represent concentrated damage at the member ends (a formulation for plastic hinges in framed structures subjected to strong earthquakes). The results of the model updating and subsequent damage detection when the rotational springs (RS model) were used were compared with those obtained using the conventional frame elements (FS model). …”

    Shaking Table Test Study on the Earthquake Behavior of High-Speed Railway Bridge Pier with Rounded Rectangular Cross Section by Xin Kang, Yongjian Zuo, Leqiao Zeng, Linna Peng, Qiliang Wang, Xiaoxiang Wang, Libin Deng, Jia Hu, Zhuo Li, Likun Li

    Published 2022-01-01
    “…However, the performance of such piers under seismic scenarios has not been well studied. To study the earthquake behavior and damage of rounded rectangular cross section piers under different intensities of earthquake excitation, nine scaled pier specimens were constructed and tested on the shaking table. …”

    Pseudodynamic Testing of Buildings Retrofitted with External Steel Reinforced Concrete Frames to Increase Lateral Strength for Earthquake Damage Prevention by Ju-Seong Jung, Kang-Seok Lee

    Published 2020-01-01
    “…In total, four RC frame specimens were prepared: one nonstrengthened control specimen for the cyclic loading test, one nonstrengthened control specimen, one specimen strengthened with a welded ESRCF system, and one specimen strengthened with a bolted ESRCF system for the pseudodynamic test. The earthquake response behavior with use of the proposed method, in terms of the maximum response strength, response displacement, and degree of earthquake damage, is compared with a control RC frame. …”
