Abstract

An international test-bed study on the application of smart wireless sensor network is on-going for the 2nd Jindo bridge, a cable-stayed bridge with the main span length of 344m. Total 113 sensor nodes were deployed on the bridge including couple of ultrasonic anemometers. Just after the installation of the wireless sensor network, the typhoon Kompasu struck the Korean peninsula in August, 2010, and the wind speed and synchronized acceleration data were measured. These sorts of data are very uncommon and provide a challenging chance for engineers to examine the effectiveness of the state-of-the-arts buffeting analysis approaches used in the aerodynamic design of the cable-stayed bridge. Based on the research background, a series of buffeting analysis are performed for the typhoon condition with the parametric study for the influencing variables in the evaluation of the buffeting-induced responses. The general coincidences between predicted and measured responses are estimated while the particular issues localized to the considered bridge are also discussed.
