Identification of Loads on Suspenders in Bridges Based on Measured Response Data in Time Domain
The purpose of this paper is to deal with identification of loads on suspenders.Values of the load at every moment were choosed as identification parameters, and the objective function was established using measured data of responses and corresponding simulated ones.The vibration differential equation of suspenders was adopted to obtain the formula of relationship between the load and acceleration responses with superposition method.Furthermore, a regularization technique was applied in identification calculations to improve ill-posedness of the problem to be solved.With a tied arch bridge as the real example, the load on one of its suspenders was identified.Results of identification showed that the simulated data of acceleration response were almost identical to measured ones, which indicated validity of the proposed method.
