Title

DYNAMIC ANALYSIS OF METRO RAIL BRIDGE SUBJECTED TO MOVING LOADSCONSIDERING SOIL– STRUCTURE INTERACTION

Pages

  285-294

Abstract

 This paper investigates the dynamic response of a metro rail over-bridge, subjected to moving loads. Track irregularity andtrain inertia effects are not considered. Bridge superstructure, piers and substructure are modelled using shell element, railsare modelled with frame elements and the interaction between bridge deck and piers is simulated using link supports (bearings)in SAP2000 (2014). Moving load analysis is performed for two models namely fixed base model and complete pilemodel. For complete pile model, the piles are modelled using frame elements. IS 2911: 2010 is considered to evaluate the soilstiffness properties. Modal damping ratio of 5% is adopted. Finite element method is used to perform the dynamic analysisand NEWMARK-β; method is considered to solve the equations of motion. From the comparative study between two models, and for two loading cases, it was noted that the speed of the train is a very important parameter influencing the dynamicresponse of the bridge. Moreover, the resonance phenomenon for the complete pile model was observed at lower speed comparedto the fixed base model for both the loading cases. From this study, it can be stated that a full three-dimensional (3D)multi-span simply supported bridges’ dynamic analysis is important to obtain the transient response of the bridge structure.
