“…Each element has two nodes, and each node contains six degrees of freedom. The mass matrix M rr , M bb , stiffness matrix K rr , K bb and damping matrix C rr , C bb of the bridge and track can be easily calculated via the finite element method [32,33]. The damping matrix C bb of the bridge adopts Rayleigh damping, which can be composed of a mass matrix M bb and stiffness matrix K bb in a linear way.…”

With the increase in the occupancy ratio of bridges and the speed of trains, the probability of trains being located on bridges during earthquakes increases, and the risk of derailment increases. To investigate the influence of unequal-height piers on the dynamic response of high-speed railway train bridge systems, a seismic action model of high-speed train–track–bridge dynamic systems was established based on the in-house code using the finite element method and multi-body dynamics method. It is found that (1) compared to equal-height piers, the peak lateral dynamic response of unequal-height piers (with gradually increasing pier heights) decreases, while the peak vertical dynamic response increases; (2) the peak lateral dynamic response of unequal-height piers (with a steep increase in pier height) increases sharply, while the peak vertical dynamic response decreases; and (3) the safety indicators of equal-height piers are significantly superior to the two unequal-height pier operating conditions.

“…The electronic computer numerical method can be used to solve the variable coefficient second-order differential equation [4] - [6] .In this paper, the fourth order Runge-Kutta algorithm is used to solve the differential equations by MATLAB program. The physical parameters of the beam and masses are as follows: Table .1 shows the maximal deflection at the mid-span of the simply supported beam considering the action of load inertia, while Table2 shows the maximal deflection at the mid-span of the simply supported beam without considering the action of load inertia .…”

In order to quantitative study the loads inertia on the effect of dynamic response on a simply supported beam, a simply supported beam with a fixed section forms and different span has been calculated under two different loading modes including moving load and moving mass by numerical method by MATLAB program. The calculated results shows the exact solution of beam vibration differential equation can be calculated and a quantitative description can be made about the load inertia effects on dynamic responses of the simply supported beam. These results provide guidance to the project practice.
