Abstract:

This paper presents operational strain monitoring results of the main navigation channel cable- stayed bridge of Shanghai Yangtze River Bridge in normal traffic condition. The strain records of the hot spots in 10 critical cross sections of the bridge are collected and then analyzed. The strains due to environmental effects (wind and temperature) and operational vehicles are separated. The strain influence lines of the bridge under moving vehicles are then extracted and compared with the computed influence line from a baseline numerical model for model calibration. The statistical characteristics of the bridge strain influence lines are then analyzed, summarized by month, and presented in this paper.
