Experimental Study on Track-Bridge Interactions for Direct Fixation Track on Long-Span Railway Bridge

<div>Spring stiffness model of the direct fixation track at the rail supporting points. <i>k</i><sub>pad</sub> = rail pad stiffness (kN/mm). <i>k</i><sub>track girder</sub> = equivalent stiffness of the track girder (kN/mm).</div>
