Paper Title:
Bidirectional Moving Vehicle Load Identification from Bridge Responses
  Abstract

A time domain method on bidirectional moving vehicle load identification from plate bridge responses is proposed in this paper. The bridge deck is modeled as a plate based on the theory of plate and the vehicle loads are modeled as two groups of axle loads moving on top of the bridge deck in two opposite directions. The equation of motion of the bridge-vehicle system is formulated in state space and the bidirectional moving load identification problem is formulated as a damped least-squares problem and further solved using the dynamic programming method with regularization on the solution. Some numerical simulations show that the proposed method is correct and effective and can be used to identify the bidirectional moving vehicle loads from the bridge responses with an acceptable accuracy.
