• Critical Speed for the Dynamics of Truck Events on Bridges with a Smooth Road 

      Gonzalez, Arturo; OBrien, Eugene J; Cantero, Daniel; Yingyan, Li; Dowling, Jason; Žnidarič, Ales (Journal article; Peer reviewed, 2010)
      Simple numerical models of point loads are used to represent single and multiple vehicle events on two-lane bridges with a good road profile. While such models are insufficiently complex to calculate dynamic amplification ...
    • Determination of longitudinal profile of railway track using vehicle-based inertial readings 

      OBrien, Eugene J; Bowe, C.; Quirke, Paraic; Cantero, Daniel (Journal article; Peer reviewed, 2017)
      The longitudinal profile of a railway track excites a dynamic response in a train which can potentially be used to determine that profile. A method is proposed in this paper for the determination of the longitudinal profile ...
    • Determination of railway track longitudinal profile using measured inertial response of an in-service railway vehicle 

      OBrien, Eugene J; Quirke, Paraic; Bowe, Cathal; Cantero, Daniel (Journal article; Peer reviewed, 2017)
      The use of sensors fixed to in-service trains has the potential to provide real-time track condition monitoring to inform maintenance planning. An Irish Rail intercity train was instrumented for a period of 1 month so that ...
    • Drive-by detection of railway track stiffness variation using in-service vehicles 

      Quirke, Paraic; Cantero, Daniel; OBrien, Eugene J; Bowe, Cathal (Journal article; Peer reviewed, 2017)
      Railway track stiffness is an important track property which can help with the identification of maintenance related problems. Railway track stiffness can currently be measured using stationary equipment or specialised ...
    • Drive-by scour monitoring of railway bridges using a wavelet-based approach 

      Fitzgerald, Paul; Malekjafarian, A.; Cantero, Daniel; OBrien, Eugene J; Pendergast, Luke (Journal article; Peer reviewed, 2019)
      This paper numerically investigates the feasibility of using bogie acceleration measurements from a passing train to detect the presence of bridge scour. The Continuous Wavelet Transform is used to process the simulated ...
    • Experimental monitoring of bridge frequency evolution during the passage of vehicles with different suspension properties 

      Cantero, Daniel; McGetrick, Patrick; Kim, C. W.; OBrien, Eugene J (Journal article; Peer reviewed, 2019)
      The natural frequencies of coupled vehicle-bridge systems change with vehicle position. These changes are generally attributed to the contribution of the additional mass of the vehicle. However, other mechanical properties ...
    • Maximum dynamic stress on bridges traversed by moving loads 

      Cantero, Daniel; OBrien, Eugene J; Gonzalez, Arturo (Journal article; Peer reviewed, 2015)
      Most current research on dynamic effects due to traffic load on simply supported bridges is focused on the mid-span section of the bridge because this location corresponds to the worst static bending moment. However, the ...
    • Railway bridge damage detection using vehicle-based inertial measurements and apparent profile 

      Quirke, Paraic; Bowe, Cathal; OBrien, Eugene J; Cantero, Daniel; Antolin, Pablo; Goicolea, Jose Maria (Journal article; Peer reviewed, 2017)
      The presence of damage in a railway bridge alters its stiffness and consequently, its static and dynamic response to loading. The dynamic response of a railway bridge to loading produces a dynamic response in the passing ...
    • Train-track-bridge modelling and review of parameters 

      Cantero, Daniel; Arvidsson, Therese; OBrien, Eugene J; Karoumi, Raid (Journal article; Peer reviewed, 2016)
      This study gathers all necessary information to construct a model to calculate the coupled dynamic response of train–track–bridge systems. Each component of the model is presented in detail together with a review of possible ...
